1 Why combine access technologies?
All-fiber access networks are becoming a reality, and the penetration ratio of all-fiber-based networkaccess
versions is growing rapidly. Although the all-fiber access (FTTH) network serves as the ultimate
goal, many existing last-mile copper-based connections still have unused potential.
At the end of this paper, you will understand that combining fiber connections with last-few-meters copper
wiring in many cases represents the most economical method for fiber-access deployment. The hybrid
fiber-copper access FTTx scenario is an answer to the ever-increasing demand for rational and costsaving
existing network deployments and upgrades.
A narrow definition of FTTx includes two different hybrid fiber-access types: Fiber-to-the-Curb and Fiberto-the-Building.
In addition to these two options, this paper covers all the options that are to be found in
the world of fiber-related subscriber network access.
1.1 Current and future requirements for broadband subscriber
access
To serve the increasing bandwidth demand has become a mantra for every service provider and
infrastructure owner over the past decade. Since the use of video, including TV streaming, VoD, NPVR
and other demanding services, has become widely accessible, every operator and service provider faces
the difficult task of maintaining the right balance between necessary infrastructural investments and the
level to which the access network’s capacities are exploited.
The fact that entirely copper-based network access is slowly becoming a mostly inadequate access
solution for more than basic users is already widely accepted. Nielsen's Law of Internet Bandwidth tells
us that high-end users’ bandwidth need grows by a staggering 50% per year.
Within a few years, the demanding services that are becoming a necessary part of an operator’s offer, are
pushing the bandwidth standard toward the 100 Mb/s benchmark. The various forms of DSL access
technologies no longer cope with such demands.
2 MAD085100-GLE-010 Obr.:70-159c

Why 100Mb/s as a benchmark? Multiple HDTV sets in a single home is soon going to become a reality. A
growing share of users falls into the heavy web-user category. This means video blogging, YouTube
addiction, and 24/7 content down- and uploading.
End users demand the highest possible quality. It is time for the next-generation access network.
2 Why decide for FTTx?
If an operator is facing a dilemma as to whether or not to build an entirely new FTTH subscriber access
infrastructure or to upgrade the infrastructure using the combined fiber-copper FTTx solutions, here are
the four major answers to the dilemma. In short, the deployment of FTTx-oriented access solution results
in a quickly gained competitive advantage over competitive wireline and wireless network operators, the
optimal re-use of the existing copper infrastructure, a decreased capital expenditure and an improved
return on investment ratio.
General FTTx pros:
• Reduced demand for all-fiber connections – lower CAPEX,
• Less digging and in-house wiring interventions,
• Faster deployment of the high bandwidth service offer,
• 24-hour life-line support.
2.1 Improve your market position faster
Every network operator is aware that every week counts when struggling for the subscriber base in a
highly competitive market. Basically, there are two ways of retaining the current number of subscribers:
• by keeping the monthly bill lower than the competition,
• by offering a better service quality.
Keeping the monthly bill as low as possible may not be an optimal solution, especially over the long term.
Indeed, it is the quality and end-user satisfaction that are going to ensure long-term profitability. And this
is what FTTx is all about. It quickly upgrades the existing copper access infrastructure with high-end
capabilities without the need for additional, expensive cable dig-ups in the last mile. It is a well-known fact
that the last 100 meters of cable are the most expensive and that they require lots of time to be laid.
2.2 Optimal for existing copper infrastructure owners
If it is there, why not use it? Past deployments and recently 1 unveiled global plans and FTTx-based
network access deployments prove that copper connections are going to represent a very significant
share of the end-user connections for the next couple of decades. FTTx boosts the unused potential of

the copper access network and turns it into a highly capable and future-proof access solution for
residents and SOHO business users.
The global trend in existing network upgrading shows that operators have three main goals:
• To offer a broadband service to a new area (where the current infrastructure is inadequate);
• To upgrade the existing broadband service to higher speeds and to offer IPTV, VoD, HD and
other services;
• To avoid decreasing the quality of the broadband service where DSL penetration is high
(interference issues).
2.3 Lower deployment costs
FTTx is a cost-optimized network-access solution for existing network upgrades. FTTx has been proved
to result in much lower fixed and variable costs in comparison with other access network deployment
options with similar capabilities.

3 Network Access deployment scenarios
FTTx represents a versatile and flexible approach to constructing the network’s last mile. It generally
includes Fiber-to-the-Curb (FTTC) and Fiber-to-the-Building (FTTB) architectures with multiple
deployment scenarios.
Iskratel has shaped the following typical hybrid fiber-copper access solutions, suitable for every technical
or economical requirement listed under the fiber-to-the-curb or fiber-to-the-building scenarios:
1. FTTC
• FTTC with VDSL2 for existing residential and business subscriber connection upgrades
with large network capacity requirements.
• FTTC with ADSL2+ for existing residential subscriber connection upgrades.
2
The deployment costs for different access technologies depend on the regional specifics. The differences may be
smaller in areas with a higher population density.

Obr.:70-159c
2. FTTB
• FTTC with POTS for the migration of legacy POTS subscribers to VoIP-controlled
networks.
• FTTC with Combo Access (POTS and ADSL2+) for future-ready upgradable voice or
DSL connections.
• FTTB with VDSL2 for very-high-capacity subscriber connections in existing multi-tenant
buildings.
• FTTB with ADSL2+ for existing in-building residential subscriber connection upgrades.
• FTTB with POTS for the migration of legacy POTS subscribers to IP-controlled networks.
• FTTB with Combo Access for future-ready upgradable voice-connection upgrades.
• FTTB with Ethernet (ETTH) combined with Ethernet for new multi-tenant buildings with
UTP wiring.

Fiber and copper-access technologies are not as competitive as it might seem. They work hand in hand
when providing a high-capacity and cost-optimized residential or business subscriber access. The hybrid
access combination of Fiber-to-the-Curb and VDSL2 is an excellent option for service provisioning over
existing copper lines from a nearby street cabinet (Iskratel ODU-M or ODU-S shelters).
Typically, the FTTC solution combined with VDSL2 subscriber access allows data-transmission speeds
up to approximately 100Mbit/s (distances up to 1 km) for a single end-user connection. Such a capacity
makes the access option suitable for a complete Triple-Play service offer on the existing last-mile wiring.

FTTC with VDSL2 pros:
• Reuse of the existing copper wiring,
• Enhanced performance over shorter line distances (up to 1 km).
3.1.1.1 Typical use
The FTTC+VDSL2 option serves as an optimal access solution for residential and SOHO business users
that require high bandwidth and are already connected via existing copper lines to the narrowband
network (POTS or ISDN). Using the hybrid access solution, the existing narrowband network is upgraded
to high-capacity data links, while the POTS itself may be upgraded to an IP-based connection (see
Section 3.1.3).
The subscribers are connected to the SI3000 MSAN access node, which is located at a nearby street
cabinet (at distances normally shorter than 1 kilometer). The access node in the outdoor shelter is
equipped with Iskratel VDSL2 subscriber blades and uses a fiber uplink to the network operator’s central
office. Iskratel also offers smaller ODU-S cabinets that are intended to cover smaller subscriber areas.
The local loop in this case is less than 1 kilometer long. On such short distances, the maximum
transmission speeds reach 100 Mb/s downstream with 50 Mb/s upstream. The shorter distance between
the shelter and the subscriber also requires less bandwidth delivered to the shelter.

3.1.2 FTTC with ADSL2+
Compared to the previously described FTTC with the VDSL2 deployment option, the FTTC with ADSL2+
ensures broadband connectivity over larger distances. Using the ADSL2+ access technology an operator
connects the subscribers at distances of up to five kilometers and still provides them on shorter distances
with up to 20 Mb/s of downstream data-transmission speed.
FTTC with ADSL2+ pros:
• Broadband evolution: the “natural” option for a dial-up upgrade,
• The reliable option in cases of questionable quality of the copper wiring,
• Mature, standardized, fully interoperable, and low-cost technology.
3.1.2.1 Typical use
Fast broadband access deployment in urban, suburban and rural areas. FTTC with ADSL2+ is especially
suitable for areas with more dispersed subscribers (better downstream performance over longer
distances compared to VDSL2).
The Iskratel SI3000 MSAN access node equipped with ADSL2+ blades enables the streaming of multiple
high-definition channels on a single subscriber port. In other words, the ADSL2+ blade allows at least two
high-definition TV channels on a single DSL port for every subscriber connected to the same blade. All
the necessary QoS and security parameters are guaranteed.

3.1.3 FTTC with POTS
Voice telephony still remains an important user-connection type. There are three typical situations in
which the network operators should decide for the FTTC+POTS deployment.
1. To deploy the FTTC+POTS solution serves as a means of PSTN subscriber migration. It helps
modernize the network infrastructure elements with IP connectivity after the completed life span
of the TDM technology in a very economical manner.
2. Many network operators still have a significant share of subscribers that do not want to switch to
broadband access technologies. In such a scenario, the FTTC+POTS solution, controlled by the
Iskratel SI3000 CS softswitch, serves as a TDM network substitute.
3. The POTS line still presents the most economical way to ensure a lifeline-enabled subscriber
connection with a 24-hour battery backup reserve provided in the shelter and no significant
worries about the battery exchange as in the case of VoIP over broadband access.
3.1.3.1 Typical use
The FTTC+POTS option is the most appropriate IP-based access solution when at least one of the
residential voice subscribers wants to retain an existing POTS connection and analog phone sets. By
deploying the FTTC+POTS access solution, the network operator solves the problem of the necessary
maintenance of the old TDM exchange.
The subscribers are connected to the SI3000 MSAN access node, which is located at a nearby street
cabinet. The access node in the outdoor shelter is equipped with Iskratel POTS subscriber blades and
uses an Ethernet fiber uplink to the network operator’s central office.

Using the Selective Power Control (SPCTM) function, a 24-hour life-line support
is provided with minimal battery and power-supply costs. If an electrical blackout
happens, the batteries power only the narrowband (voice telephony) interfaces.
In such a case, the broadband ports or blades are shut down. By using this
mechanism, the 24h life-line is provided in the most economical way.
SPC TM benefits:
• Lower costs of battery exchange,
• Less required battery space: smaller shelter with less visual impact on
the environment.
3.1.5 FTTC with Combo Access
Combo Access represents a combination of the POTS and ADSL2+ connection on a single subscriber
board. The combined access is optimal in cases when the operator wishes to preserve the maximum
flexibility of the subscriber access type. The basic POTS connection is quickly upgradeable with the high-

capacity broadband ADSL2+ connection using a single administrative action and a single SI3000 MNS
network management application.
FTTC with Combo Access pros:
• “The” choice for fast ADSL2+ broadband deployment;
• Combo Access answers the regulatory demands for the POTS line in
the case of broadband subscribers;
• Subscription change without on-site administrative actions: lower
OPEX.
3.1.5.1 Typical use
Combo Access represents a great advantage when the penetration of broadband subscribers in a certain
region is going to rise quickly. By using the combined subscriber boards, the voice-telephony user is
connected with a POTS/ADSL2+ connection from the start. Future switching to a pure broadband
connection is therefore fast and, what matters the most, it does not represent any additional costs since
all the subscribers are pre-wired with both access types.
The Combo blade is equipped with combined ADSL2+/POTS ports and integrated splitters. The
elimination of the outside splitters greatly simplifies the system complexity and reduces the amount of
cabling needed.

The high-speed VDSL2 connection allows an up to 100/100 Mb/s per subscriber connection over a short
distance. Therefore, the achieved bandwidths within the building’s network are comparable to those of
optical or UTP connections, while using the existing copper wiring.
The combination of FTTB and VDSL2 access technology serves as a cost-optimized and time-efficient
option for the introduction of demanding Triple-Play services, gaming, teleconferencing and VPN access.
10 MAD085100-GLE-010 Obr.:70-159c

FTTB with VDSL2 pros:
• High quality and short copper pairs with no cross-talks allow the use of
higher VDSL2 profiles (30a with 100Mb/s up- and downstream and
17a with 100Mb/s downstream and 50 Mb/s upstream).
• Appropriate for existing infrastructure upgrades.
3.2.1.1 Typical use
The FTTB with the VDSL2 hybrid access solution connects the subscribers in multi-tenant buildings using
the SI3000 MSAN VDSL2 blade. The in-building access node is placed inside the compact Iskratel IDU-M
indoor shelter.
The in-building SI3000 MSAN transforms the existing wiring that was previously used as a voice-only or
low-speed broadband connection into broadband-enabled user connections that are terminated by the
Iskratel Proteus VDSL2 home gateway.

3.2.2 FTTB with ADSL2+
Using ADSL2+ inside a multi-tenant building is an alternative option to the VDSL2 access technology.
Despite allowing less bandwidth, the ADSL2+ connection’s advantage is robustness, high interoperability
and, in many cases, an optimal price/performance ratio.
The ADSL2+ connections over the existing in-house wiring represent a highly capable Triple-Playenabled
communications infrastructure.
FTTB with ADSL2+ pros:
• Convenient for buildings with average quality wiring.
• Price optimized for areas with bandwidth demand up to 24 Mb/s.
3.2.2.1 Typical use
The FTTB with ADSL2+ access solution connects the subscribers in multi-tenant buildings using a
SI3000 SI3000 MSAN with ADSL2+ blades. The in-building access node is placed inside the compact
Iskratel IDU-M indoor shelter.
In the case of FTTB with ADSL2+, the in-building SI3000 MSAN transforms the existing wiring into
broadband-enabled subscriber connections that are terminated by the Iskratel Sinope ADSL2+ home
gateways.

Voice telephony still remains an important user-connection type. There are three typical situations in
which the network operators should chose an FTTB+POTS deployment (see Section 3.1.3 for a more
detailed explanation):
• PSTN migration,
• a significant share of voice-only subscribers,
• life-line support.
FTTB with POTS pros:
• The ability to deploy the proprietary POTS voice lines in countries
where apartment owners are also wired infrastructure owners.
• Ideal for newly built buildings with in-house exchange systems.
• Less power needed for analog phone powering.

uildings with common UTP wiring, the FTTB+Ethernet access solution represents a cost-effective, easyto-deploy
technology for service providers in multi-tenant buildings and enterprise campus environments
with broadband access.
FTTB with Ethernet pros:
• Ideal for buildings with existing UTP wiring or easy-to-deploy UTP wiring;
• 1U switch enables a lower-price access solution compared to other BB
access options;
• No CPE required in the case of pure internet access.
3.2.4.1 Typical use
The FTTB+Ethernet access solution connects the subscribers in multi-tenant buildings using the Iskratel
1U Ethernet switches and the in-building SI3000 MSAN access nodes that act as an aggregation switch.
A building is equipped with single SI3000 MSAN access nodes and, when the number of inhabitants is
larger, multiple 1U switches nodes located on each floor or at each entrance. The maximum length of the
UTP cable between the 1U switch and the apartment doors is, in practice, 70 m.

4 Shelters
Shelters for the Iskratel remotely deployed FTTx networking equipment are available as a completely preequipped
and pre-tested plug-and-play solution. Both the outdoor shelters and indoor cabinets are
equipped with a complete telecommunications infrastructure (active equipment, power supply, batteries,
cables, distribution frame) needed for the carrier-grade Telco environment.
Outdoor shelters (ODU-M and ODU-S) can operate in practically any environmental conditions. They are
equipped with a heat exchanger and an air-conditioning system and are therefore designed for outdoor
use with a temperature range from -50°C up to +50°C. The IDU-M indoor shelter is designed for operating
in a weather-protected environment with a temperature range from -5 to +45°C.
Shelter installation requires minimum effort and expense due to the plug-and-play concept of the Next-
Generation Access solution. All that is needed is to connect the power cables, the optical uplink cable and
the subscribers’ copper pairs.
4.1.1 ODU-M Outdoor Shelter for FTTC Solutions
The Iskratel ODU-M outdoor shelter is designed for larger-scale FTTC access solutions in rural, suburban
and urban networks. The shelter brings the entire fiber-based user connection closer to the users in an
economical way.
The ODU-M fits with all the equipment required for undisturbed and autonomous operation. It excels in
terms of:
• wide operating-temperature range (-50°C to + 50°C),
• low power consumption,
• small mounting space,
• maximized capacity,
• easy maintenance.
The size of the ODU M allows the deployment of a single SI3000 MSAN access node as a MEA 20
package.
A single ODU-M shelter has a capacity of up to 576 ADSL2+/VDSL2 lines with splitters or 1056 POTS
lines.
On-site intervention is very simple because all the equipment can be accessed from the front side. The
distribution frame is in a separate compartment, accessed from the right-hand side.
The outdoor shelter, ODU-M, also accommodates a battery-supported power-supply system MPS1000.50
with up to 196 Ah of battery reserve. It includes an integrated distribution frame, a heat exchanger and
elements for the protection and management of the system operation. All the system elements are
managed from a central SI3000 management node.

4.1.2 FTTC ODU-S Small Outdoor Shelter for FTTC Solutions
In the cases of a more dispersed subscriber distribution, Iskratel recommends designing the FTTC
access solution around the compact ODU-S outdoor shelter.
The ODU-S shelter represents a very cost-optimized (half the prices of ODU-M) sheltering solution with
only 45 cm of depth, full vandal resistance, a steel construction and 24-hour battery support for the POTS
subscriber lines.
The shelter is equipped with the Iskratel MPS1000.25 and remote powering RPS power supply. It offers
enough volume for a single SI3000 MSAN access node in a MEA10 package.
A fully equipped ODU-S shelter connects up to 128 VDSL2, 192 ADSL2+ or 576 POTS subscribers.
4.1.3 IDU-M Indoor Cabinet for FTTB Solutions
The IDU-M shelter is designed for cost-efficient FTTB solutions in suburban and urban networks. The
main advantage of the IDU M is that it efficiently integrates all the equipment required for undisturbed and
autonomous operation. The IDU-M excels in terms of its low power consumption, extremely small
mounting space, maximized capacity and easy maintenance.
On-site intervention is very simple because all the equipment can be accessed from the front side with
separate access to the equipment and the distribution frame compartments. Built in lamps facilitate
interventions in night-time conditions.
16 MAD085100-GLE-010 Obr.:70-159c

The IDU M also accommodates a battery-supported modular power-supply system, an integrated
distribution frame, an intelligent filter fan system and elements for protection. All the system elements are
managed from a central management node.
The shelter is equipped with the Iskratel MPS1000.25 and the remote powering RPS power supply with
24h of battery reserve for the POTS subscriber lines.
It offers enough volume for a single SI3000 MSAN access node in a MEA10 package.
A fully equipped IDU-M shelter connects up to 216 VDSL2, 288 ADSL2+ or 576 POTS subscribers.
5 Power Supply
The shelters deployed in FTTC and FTTB access solutions are powered locally or remotely by the Iskratel
Modular Power Supply (MPS) system. Local or remote powering options ensure an uninterrupted and
centrally managed power supply for CO and remote access network elements.
The benefits of using the Iskratel MPS power-supply system:
• central management with SI3000 MNS network management system;
• modular design;
• high efficiency (>93%);
• turn-key power-supply solution;
• battery control and capacity measurement;
• environmental control and reporting;
• wide range of DC/DC and DC/AC current-converting options.
The MPS 1000 is a modular power-supply system with capacities that can be adjusted to the power
requirements of users, within the framework of predefined power capacities. Iskratel provides the market
with a maximum-output power supply of 1500 A. Typical FTTC and FTTB access solutions include the
MPS1000.50 or 1000.25 power-supply systems.

The RPS remote-powering system is the cost-saving way of providing the power supply for remote
networking equipment in various FTTC and FTTB scenarios. The system enables the reuse of copper
links that were made obsolete by newer CO remote cabinet optical connections for the remote power
feeding of access nodes.
A single central part of the RPS system allows the use of up to 24 copper pairs with up to 100 W of power
per single pair. The remote part includes up to four receiving modules with up to three copper pairs per
single module. Each module receives 73 W of maximum power per single pair.
To remotely power the access nodes in FTTC and FTTB solutions ensures an uninterrupted 24/7 power
supply with full autonomy (central battery backup). RPS therefore makes the use of remote batteries
obsolete. Additionally, all the environmental and legal issues with local powering, such as electrical
counters, building-owner permissions and power-outlet installations, are solved.
5.1.1 RPS Characteristics
The RPS capacity depends on the loop length and the resistance. The table below shows the maximum
distances at a given loop resistance and the transmitted power (in the case of a 100-W input power):
