Legacy Upstream TX DFB Upgrades

**DISCONTINUED**

ATX’s HFC Enhance line offers a comprehensive assortment of upgrade or replacement modules for legacy nodes from a variety of manufacturers, without the adaptive clipping mitigation of the ART. Product offerings include transmitters (1310/1550, F-P, DFB, and CWDM) and receivers (870 and 1000 MHz). ATX also offers cost-effective node segmentation solutions.

Drop-in node upgrade modules include but are not limited to the following*:

ADC / C-COR: ISX-3022 / 3030 / 3040
Cisco / Scientific-Atlanta: 6920, 6940, 6942 and 6944 Gainmaker

Node segmentation solution offerings include but are not limited to the following*:

ADC / C-COR: ISX-30XX
Cisco / Scientific-Atlanta: 69XX

Features

HFC Enhance Drop-in Node Upgrade Modules

Allows for an overall node performance enhancement in a cost-effective and time-efficient manner
A variety of laser technologies (F-P, DFB, CWDM) and powers (0-3 mW) allows operators to satisfy any application
Dual transmitter option in the module increases number of return path segmentations possible and/or offers an option for implementing fiber link redundancy
Dual transmitter option (module specific) in conjunction with CWDM allows for ultra space-efficient node segmentation solutions
Low input requirement on receiver modules (-8 to +2 dBm) in conjunction with high RF output allow operators to split forward path without degrading CNR
Unique low power designs minimize thermal dissipation thereby increasing module performance and lifetime
See individual module datasheets for more details

HFC Enhance Node Segmentation Solutions

ATX’s HFC Enhance segmentation solutions allows operators to segment legacy/unsupported nodes both cost-effectively and with minimal customer service disruption
ATX’s transmitters and receivers ensure optimum network performance is achieved
Use of WDM/CWDM/DWDM technology allows for full segmentation up to full 4×4 without the requirement for additional fibers
Far more cost-effective solution versus deploying new nodes when viewed from a capital expenditure and labor standpoint
Designed for easy installation to minimize customer service disruption time
