Overview 

FTTx ignites a technology shift from the existing copper cabling systems to fiber, 

which provides almost unlimited transmission rates. Since fiber networking is a proven 

broadband technology with virtually no limits, it can be expanded any time to meet 

bandwidth demand of individual customers over the upcoming years. In this FTTx 

solution guide, ZyXEL provides solutions for all possible forms of fiber infrastructure and 

ways to leverage existing DSL deployments for the best synergy. 

Market Trend 

FTTx is the fastest-growing global 

broadband technology with significant 

deployment in Asia, Europe and North 

America. The global FTTH ranking shows 

that six million new fibre access subscribers 

were increased till the end of 2009. 

The top five economies in terms of the total 

worldwide subscription are Japan, China, 

South Korea, USA and Taiwan. They also have 

in common that they are the only countries 

in the Global Ranking with more than one 

million households connected to FTTH/B.

Driving Force of FTTx: High-definition IPTV is one of the key 

drivers of FTTx, with which 2+ simultaneous HD streams for 

multi-room IPTV services will become the major trend in 

the upcoming years. Green environment issues are another 

driving force because fiber deployment produces less CO2 

than copper wires.

Background of AON and PON: 

■ Active Optical Network, Active Fiber or Active Ethernet 

(AON) 

Active fiber is a dedicated medium in which each end user 

is allowed independent access. Each end user has a home 

gateway with active fiber directly connected to the carrier 

Ethernet switch in the central office or street cabinet by a 

direct fiber. Between the central office and the end user, 

there can also be an aggregation Ethernet router if needed.

■ Passive Optical Network (PON) 

PON is a shared medium in which a fiber is “passively” split 

into many end user connections. The term “passive” refers 

only to the optical splitter, which does not require external 

electrical power to function. Each end user has one GEPON 

Figure E: The ZyXEL PON Solution 

Optical Network Unit (ONU) or GPON Optical Network 

Terminal (ONT) while the fiber terminates at a central office 

in an Optical Line Terminal (OLT) that requires electrical 

power. Between the OLT and the ONU/ONT may be one or 

two stages of passive splitters that split the connection to 

multiple end points.

Active Fiber Solution 

Benefits: 

■ Flexible bandwidth offering from 100/100 Mbps to 

Gigabit/Gigabit throughput per subscriber 

■ Breakthrough business model with matured and 

proven Ethernet technologies 

■ Offer RF-over-Glass technology to provide highquality 

TV services 

■ Lower CAPEX on equipment investment, lower 

OPEX for matured SNMP and TR069/TR104 network 

management and provision equipments 

“Open Access Model” is an emerging operator-neutral 

business model to offer ICT infrastructure and network 

services suitable for FTTx solutions; the potential customers 

include telco operators, service providers, MSOs, content 

providers and users from government, banking, education, 

military, police, broadcasting as well as utility companies 

or agencies. The P2P active fiber is the best solution to 

meet all the requirements of aforementioned customers. 

The P2P active fiber solution has some advantages as well: 

such as easy management, matured standard technology, 

dedicated bandwidth offering and the future-proof access 

architecture. 

ZyXEL offers a complete end-to-end Gigabit and 100 Mbps 

active fiber solution; all active fiber CPE products support 

both SNMP and TR069/TR104 to meet network management 

demands from various customers. Please refer to the 

following application figures and supported product tables 

for more details. 

The Figure 1-1 describes the roles of open access model, 

in which municipalities or utility companies play the role 

as the infrastructure owner, while Telcos, MSOs and service 

providers play the role of network operators or service 

providers to offer related services to residential or SMB 

users. Multi-site users will be the enterprise subscriber to 

subscribe the Internet infrastructure, as an extension to the 

intranet, from network operators or service providers. 

Telcos can rent the active fiber pipe, deploy their own COE 

and CPE, and then offer high-quality Triple Play services 

to subscribers. Please refer to the figure 1-2 that indicates 

the FTTx applications through open access model and the 

figure 1-3 that indicates the equipment owner. 

For MSO operators, please refer to the figure 1-2. Since 

active fiber supports RF-over-Glass (RFoG), MSO operators 

can transform their CATV over active fiber pipe and offer 

high-quality Triple Play services to their subscribers. For 

multi-site users, please refer to the figure 1-3; the users will 

deploy their own security routers on the extended intranet 

through open access network services.

GEPON Fiber Solution 

Benefits: 

■ Flexible bandwidth offering from 39/39 Mbps to 

1.25/1.25 Gbps per subscriber 

■ The affordable solution to meet various FTTx 

applications including FTTH, FTTC, FTTN, FTTB and 

FTTP 

■ Offer RF-over-Glass technology to provide highquality 

TV services 

■ Lower CAPEX on GEPON total solution investment, 

lower OPEX by employing ZyXEL’s proven centralized 

GEPON network manager 

GEPON is the most widely deployed and matured technology 

with advantages like easy management, cost effectiveness 

and easy sharing. It is a good solution for FTTH applications. 

MSOs can use its RF-over-Glass (RFoG) feature as their nextgeneration 

cable PON to upgrade broadband bandwidth 

and expand customer base. 

Today’s service providers are demanding larger bandwidth 

for subscribers to offer High-Definition Television (HDTV), 

MoD, VoIP and online gaming services. The options for 

service providers to deliver decent bandwidth are still 

dependent to the mixed network architecture, and the 

demands are being met by the deeper penetration of fiber 

optics in the Access Networks. 

Although CATV companies now provide over 100 Mbps 

service with DOCIS 3.0 to compete with ILEC/CLEC, they are 

now considering fiber deployment for providing services 

such as Triple Play services (please refer to the following 

application figure-2). Besides, the HFC plant brings 

reliability/availability, powering and potentially disruptive 

upgrades into question; on the contrary, fiber has better 

reliability and PON has few plant electronics, use less power 

and are easier to upgrade. 

On the CO side, video signal received from satellite to video 

head-end goes through amplifiers to amplify the signal. A 

WDM combines the wavelength of broadcasting video 

(1550 nm) and IP data (1490 nm) to transmit through 

the fiber of outside plant to home users. The WDM on 

the user side is to divide the wavelength to two different 

wavelengths (1550 nm, 1490 nm) to different transceivers. 

V-ONU demodulates 1550 nm signal for broadcasting video 

programs. GEPON-ONU demodulates 1490 nm for IP data 

transmission.

Benefits: 

■ Complete end-to-end ADSL2+ solution from central 

MSAN, remote MSAN and DSLAM, residential 

gateways/bonding gateways/VoIP IAD to SOHO 

security gateways 

■ Excellent performance from service plans tailormade 

for individual service providers 

■ Support Annex A/L/M 

ADSL2+ (ITU G.992.5) doubles the bandwidth used for 

downstream data transmission, which effectively doubles 

the maximum downstream data rates, to achieve rates up to 

20 Mbps on telephone lines as long as 1,524 meters. ADSL2+ 

solutions will interoperate with ADSL, ADSL2 and ADSL2+. 

ADSL2+ includes all the feature and performance benefits 

of ADSL2 while maintaining the capability to interoperate 

with legacy ADSL equipments. 

The demand for greater bandwidth for Internet never stops 

rising. No matter it’s for multimedia applications or a more 

cost-effective means for enterprise connectivity, vendors 

are not only expanding their lineup with new models, they 

are adding value with new features as well. Today, ADSL2+ 

is the mainstream xDSL modem technology and the most 

deployed one in the world. 

ADSL2+ provides Internet access via standard copper 

phone lines while it still allows users to make phone calls 

over the same line. ADSL2+ boosts this to 24 Mbps over the 

same phone lines and connection distance of up to 1,828.8 

meters. 

ZyXEL targets the MSAN and ADSL2/2+ CPE functionalities 

at improving performance, interoperability and supports 

to new applications, services and deployment scenarios. 

Among the changes are improvements in data rate and 

reach performance, rate adaptation, diagnostics and standby 

mode, etc. 

14

The main “Better Rate and Reach” enhancement of ADSL2/2+ 

improves modulation efficiency, reduces framing overhead, 

achieves higher coding gain, improves the initialization 

state machine and provides enhanced signal processing 

algorithms. 

ZyXEL offers a complete end-to-end ADSL2+ solution with

2. G.SHDSL.bis with EFM Solution 

Benefits: 

■ Maximize the performance of copper wire with 

higher speed and longer coverage distance 

■ Provides 2-pair, 4-pair and 8-pair bonding with 

symmetric bandwidth of up to 45 Mbps 

■ The best replacement solution for legacy and 

expensive lease lines 

Ethernet-in-the-First-Mile (EFM), also known as IEEE 802.3ah, 

is a matured technology for delivering symmetric bandwidth 

to businesses, government offices and organizations with 

multiple locations (multiple-site). It allows continuous 

standard Ethernet network to reach across the globe, 

eliminating non-native transport such as Ethernet over ATM 

from the access networks. EFM delivers up to 5.7 Mbps per 

line with standard equipment supporting up to bonding 

— a relatively high-performance connection with up to 

45 Mbps bandwidth symmetrically with high stability, low 

delay and low packet loss. 

Today’s carriers are eager to connect business customers 

to their metro networks. The G.SHDSL.bis EFM technology 

is the best solution for enterprises with the demand to a 

certain amount of transmission over symmetric bandwidth. 

It has advantages of maximizing the performance of copper 

wire with higher speed and longer distance coverage. By 

leveraging pre-installed bundles of twisted-pair cable to 

deliver the first-mile broadband network access, ZyXEL 

bonded G.SHDSL.bis with EFM solution to smoothen the 

issues of fiber-optic cable installation. In addition to offering 

different bandwidth packages by using the G.SHDSL. 

bis bonding technology, this is the best solution that 

enables carriers to expand service offerings in high-margin 

enterprise markets. 

The use of IP over Ethernet in subscriber access applications 

eliminates unnecessary network layers. It reduces the 

number of elements on a network as well as the equipment, 

operational and complexity costs. Simple architectures 

are always easier to manage, especially in complicated 

central environments. In the first mile, native Ethernet on 

copper or optical fiber networks will provide significant 

cost advantage over other technologies. These IP/Ethernet 

networks can coexist with Time-Division Multiplexing 

(TDM) services. 

ZyXEL’s P792 G.SHDSL.bis Series complies with the ITU-T 

991.2 G.SHDSL, G.SHDSL.bis and IEEE 802.3ah standards 

and offers superior Ethernet connection reliability with 

unmatched rate and reach. The P-793H Series and P-794H 

complies with ITU-T G.998.1 (G. Bond) and supports 4-wire/8- 

wire bundle for higher bandwidth and longer distance.. 

With ZyXEL’s End-to-End G.SHDSL.bis with EFM Solution 

for business customer edge on customer premises, service 

providers can quickly and cost-effectively introduce 

profitable broadband services to businesses, governments, 

schools and other organizations by fulfilling the demand for 

higher bandwidth with manageable cost. Please refer to the 

application diagram and supported product tables for more

3. Bonded ADSL2+ with Annex M Solution 

Benefits: 

■ The fastest way to achieve positive revenue returns 

associated with Triple Play bonded ADSL2+ gateways 

is to deliver these services over existing copper 

loops, of which there are over 450 million worldwide 

■ Bonded ADSL2+ delivers great data rates over longer 

distance than the basic ADSL2+ 

■ Lower CAPEX on investing equipment, lower OPEX 

for matured SNMP and TR069 network management 

and provision equipments 

ZyXEL’s boneded ADSL2+ with Annex M solution on the 

existing networks for Telcos and service providers. The 

solution offers downstream bandwidth of up to 48 Mbps 

and upstream bandwidth of up to 5 Mbps using the 

bonding and Annex M technologies on two phone lines. We 

also offer a solution for bonding a larger number of phone 

lines; ZyXEL generally recommends the use of standard 

G.998/G. Bond technology for bonding multiple ADSL lines. 

The alternative solutions based on non-standard bonding 

or load-balancing techniques such as IP tunneling may have 

a role to play in certain deployments and we can provide 

solutions of this type too. 

Annex M is an optional specification in ITU-T recommendations 

G.992.3 (ADSL2) and G.992.5 (ADSL2+). This specification 

extends the capability of commonly deployed Annex 

A by more than doubling the number of upstream bits. The 

data rates can be increased easily depending on the distance 

from the DSLAM to homes of the customers. It complies 

with G.992.1 (G.dmt) Annex A compliant/G.992.2 (G. 

Lite), Annex A/L/M and G.998.1 (G. Bond-ATM) ATM-based 

multi-pair bonding. 

Loop bonding technology provides the telecom industry 

with a revolutionary technique to combine multiple 

ADSL2+ connections into a single, aggregated connection. 

Supporting up to 48 Mbps downstream and 2 Mbps 

upstream data rates, as well as high-speed data and derived 

voice applications, service providers can offer advanced 

bandwidth-dependent services such as broadcast video 

and VoD to customers beyond the reach of central offices 

or digital loop carriers. Bonded ADSL2+ supports multiple 

high-definition television streams at significantly longer 

distances than other existing xDSL technologies. 

ZyXEL’s bonded ADSL2+ with Annex M solution provides 

the existing ISPs with opportunities to target the profitable 

SOHO and SMB markets by differentiated and customized 

ser vices. The superior downstream and upstream 

capabilities of bonded ADSL2+ combined with relatively 

low cost makes the solution particularly attractive to SOHO 

and SMB users. The significant attraction to the existing ISPs 

is that only part of their existing infrastructures needs to be 

upgraded and this can be achieved on a gradual basis as 

subscription to the services increases. 

ZyXEL’s bonded ADSL2+ with Annex M solution allows 

service providers to double the bandwidth over the existing 

copper infrastructure and thus leverage their investment to 

quickly deploy revenue-generating services like IPTV, VoD 

and other premium Triple Play applications. 

With the ZyXEL end-to-end bonded ADSL2+ solution, 

service providers can economically offer services with 

higher bandwidth coupled with 802.11n home networking 

solutions to their subscribers. This is a prime example of 

ZyXEL’s commitment to building exactly what operators 

need to remain competitive. Please refer to the application 

diagram and supported product tables for details.

End-to-End VDSL2 Solutions 

1. VDSL2 17a Solution 

2. VDSL2 30a Solution 

Benefits: 

■ Offers 100/50 Mbps (17a) and 100/100 Mbps (30a) 

bandwidth to fulfill next-generation broadband 

access requirements 

■ True DSL technology to offer multiple HD IPTV 

services simultaneously for a digital home user 

■ Backward compatible with the existing xDSL family 

■ Best-effort solution eliminates the last-mile 

bottlenecks for FTTx solutions 

VDSL2 17a, 100/50 Mbps VDSL2 Solution 

The ZyXEL Very-High-Bit-Rate Digital Subscriber Line 2 

(VDSL2) technology supports a wide range of Triple Play 

service deployments such as voice, video, data, HDTV and 

interactive gaming. It also enables operators and carriers 

to upgrade the existing xDSL infrastructure gradually and 

flexibly with limited cost. The maximum downstream 

bandwidth is 100 Mbps and the maximum upstream 

bandwidth is 50 Mbps. 

VDSL2, or G.993.2, is one of the most popular standards of the 

xDSL family and widely deployed broadband technology. It 

allows telecom operators around the world to provide 

services such as HDTV, VoD, videoconferencing, high-speed 

Internet access and advanced voice services, including VoIP, 

over a standard copper telephone cable. 

VDSL2 includes all the technical prerequisites to address 

the backward-compatibility issues of the traditional ADSL 

technology. VDSL2 offers telecom carriers a solution that 

promises to be interoperable with the ADSL kit that many 

operators already have in place. This interoperability will 

make customer migration to VDSL2 much easier. 

VDSL2 gives consumers speeds of up to 100 Mbps upstream 

and downstream at 700 feet and 20-30 Mbps between 2500 

to 4000 feet. VDSL2 is an ideal solution to work with the Fiber 

to the Premises (FTTP) rollout; for instance, fiber is supplied 

directly to an apartment block and copper cable is used to 

supply residents with high-speed VDSL2 from there on. It is 

also a perfect solution for the last-mile of FTTx deployments 

by connecting to remote MSAN via fiber optics interfaces.

VDSL2 30a, 100/100 Mbps VDSL2 Solution 

The VDSL2 30a profile technology is the best solution as 

a part of FTTB, FTTC and FTTN. Now the fiber reach range 

can be 10 km, 20 km or up to 60 km, and it is the most 

effective and low-OPEX approach by integrating the lastmile 

legacy copper lines and boosts its bi-directional 

bandwidth up to 100 Mbps. 

ZyXEL’s VDSL2 solution serves as the ideal xDSL technology 

for eliminating last-mile bottlenecks, enabling mass 

deployment of Triple Play services by TR069 for easy 

management and allowing carriers to efficiently compete 

with cable providers. VDSL2 provides high data rates of up 

to 100 Mbps symmetrically that are already a mandatory 

requirement in many regions for service upgrades. 

ZyXEL also provides access equipments of central MSAN, 

remote IP DSLAM, environment-hardened to fit in VDSL2 

transmission with a series of models in various scenarios; 

in addition, with its enhanced long loop reach capabilities, 

the VDSL2 system can cover more than 90% of the 

households within the POTS network.
