Cisco Model 6942 Four Port Optoelectronic Node 870 MHz with 55 70 MHz Split 数据表
Description
The Model 6942 Node is a high performance, four output
optoelectronic node. The Model 6942 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.
The Model 6942 Node’s reverse path is very flexible. Reverse traffic
can be combined and routed to FP or DFB reverse transmitters, and
redundant (back-up) transmitters may also be utilized. The platform
provides for reverse segmentation through the addition of
transmitters and reverse routers. Up to four transmitters - one per
reverse input port - can be configured using the eight-position optical
interface board. Where fiber counts are limited, the six-position
optical interface board also allows use of advanced Baseband Digital
Reverse, reverse path segmentation technology using Scientific-Atlanta’s bdr

system. The six-position optical
interface board has two transmitter mounting positions. If the reverse path is not segmented, one position is used
for the primary reverse transmitter and the other for an optional redundant transmitter. For dual reverse
segmentation, two transmitters are installed, each dedicated to reverse traffic from a pair of station reverse input
ports.
The Model 6942 Node can also be configured with a Scientific-Atlanta status monitoring transponder. The
transponder, in conjunction with the Transmission Network Control System (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.
