OPTICAL NODES 

MO1004 OPTICAL NODE 

• Low noise optical receiver module 

• Return path optical transmitter module 

• Segmentation in forward and return path 

• HFC and Fiber Deep versions 

• 2 high-leveled RF outputs (splittable to 2x2) 

• 1GHz GaAs or GaN Power-doubler hybrids 

• Remote powered switching power supply 

• Monitoring option 

GENERAL DESCRIPTION______________________________________________________________ 

The optical node is available in different configurations. This depends on the configuration module which can be 

ordered. CM5 configuration module allows (2 transmitter and 2 receiver modules) the segmented operation 

mode in forward and return path too. Using CM6 configuration module – can be used 2 transmitter and 1 

receiver modules – you can realize the return path segmentation. CM7 configuration module uses 1 

transmitter and 1 receiver module – in this operation mode segmented operation is impossible. CM8 

configuration module enables the redundant operation in forward and return path with 2 transmitters and 2 

receivers. In basic configuration the device contains 1 optical receiver module (FOR1000H for HFC version or 

FOR1000F for Fiber Deep version). For the optical node FP, DFB or CWDM return path optical transmitter, another 

other receiver module as well as monitoring option can be added.

GENERAL DESCRIPTION______________________________________________________________ 

The optical node is available in different configurations. This depends on the configuration module which can be 

ordered. In normal configuration node contains the CM1 configuration module which allows the operation of 1 

transmitter and 1 receiver. The second configuration allows the redundant operation by the CM2 configuration 

module. With this module 2 transmitters and 2 receivers can be operated. With CM3 configuration module you 

can realize the segmentation. This module supports 3 transmitters and 1 receiver. With CM4 configuration 

module you can realize the partial segmentation. This module supports 2 transmitters and 1 receiver. The 

block- diagrams of these modules can be seen under the node's block- diagram. 

In basic configuration the device contains 1 receiver module (FOR1000H for HFC version or FOR1000F for 

Fiber Deep version). For the optical node an FP, DFB or CWDM-ITU return path optical transmitter, another optical 

receiver module as well as the monitoring option can be ordered.

MONITORING PRODUCTS 

STANDARD HMS TRANSPONDERS (PRE-LIMINARY) 

• HMS 1.0 

• Remote software update 

• SNMP 

• To Comtech and other vendors' amplifiers and 

nodes 

GENERAL INFORMATION______________________________________________________________ 

Comtech Ltd. started to develop and produce transponders 10 years ago. Present days around 15000 

transponders can be found in our customers systems (Tarr Kft., T-Kábel). These transponders' physical conditions 

(modulation, bit-rate) are in accordance with the HMS monitoring standard but the communication between 

transponder and HMTS is realized by a unique protocol (which enables a much faster data-communication than 

the HMS protocol). We have received a lot of demand for HMS compatibility, so at the end of the last year we 

started developing our HMS compatible transponder. 

The launch of the new transponder on the market is expected in june-july 2010.
