Description
The Model 6940 Node is a high performance, four output optoelectronic node. The Model 6940 Node can be configured with a variety of forward optical receivers and reverse optical transmitters, providing flexibility for use in multiple applications.
Redundant optical receiver and transmitter capability allows optical path redundancy, enabling increased network reliability. Additionally, the Model 6940 Node is capable of reverse port segmentation using the Prisma bdr system. The bdr system utilizes Scientific-Atlanta’s unique baseband digital reverse technology and allows increased performance, reach, and bandwidth efficiency for the critical reverse network.
The Model 6940 Node’s housing incorporates many features that enhance ease of use and reliability, such as a separate AC powering port, optional redundant power supply, and extended ports to allow for easy heat shrink weather protection.
The Model 6940 Node can also be configured with a Scientific-Atlanta status monitoring transponder. The transponder, in conjunction with the ROSA/ TNCS or other compatible element management system, enables remote monitoring of critical node related parameters, and remote control of each optional reverse path switch for ingress troubleshooting.
