Cisco Model 6940 Four Port Optoelectronic Node 870 MHz with 55 70 MHz Split 数据表

 

 

 
 

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. 
 

•  1 GHz RF platform 

•  15 amperes continuous power passing 

•  Four high level forward RF outputs 

•  Screwless seizures for ease of connector installation 

•  40-90 V AC high-efficiency switch mode power supply
