CableServ® manufactures a wide range of DFB Return lasers for Legacy Optical Nodes. These Return Transmitters are offered in DFB 1310nm and 1550nm for WDM applications, as well as 1470 to 1610nm ITU CWDM wavelengths. These transmitters allow older Nodes to operate with DOCSIS traffic and offer greatly improved NPR and BER/MER over the original Fabry-Perot devices.


CableServ® Return Transmitter for Scientific Atlanta® 6920 Series Optical Nodes

CableServ® offers a series of Return Path transmitter modules for Scientific Atlanta® 6920 Optical Nodes.
The Return Transmitters are offered in DFB 1310nm and 1550nm for WDM applications, as well as ITU CWDM wavelengths (1470 to 1610nm).
Applications
• Replacement Return TX Modules.
• Upgrade of Fabry-Perot to DFB return transmitters for launch of Telephony.
• CWDM Modules for multiplexing upstream data on a single fiber.
These high performance return transmitters perform equal to or better than the original manufacturer’s products. For Cable Operators launching Telephony, CableServ offers DFB return transmitters that directly replace the original low performance Fabry-Perot devices, offering increased performance. Also offered are High Gain versions, which allow 2:1 Return Segmentation. CableServ Transmitters are footprinted so that a second transmitter module may be installed in an unused Receiver or Status Monitor slot for segmentation.
