Single Link: Receive-Only Topology - Cisco SCE 2000 Quick Start Manual

Information About Cabling
Figure 5-1
PWR B STATUS
PWR A
In the single link inline topology, either the first GBE link (first two ports) of the SCE 2000or the second
GBE link (third and fourth ports) can be used, as illustrated in the diagram above. The remaining pair of
ports is unused.
Either port 1 or port 3 is used for connecting to the network element that is deployed on the subscriber
side of the SCE 2000 while port 2 or port 4 is used for connecting to the network element that is deployed
on the network side of the SCE 2000.
Inline topology requires both Receive and Transmit fibers

Single Link: Receive-only Topology

In this topology, an optical splitter resides physically on the GBE link that the SCE 2000 should monitor.
The optical splitter is connected to the SCE 2000 via Rx links only.
In this topology, the traffic passes through the optical splitter, which splits traffic to the SCE 2000.
Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN
Note
functionality that includes separation between ingress and egress traffic and multiple SPAN-ports
destinations.

The single link receive-only topology cabling is similar to that for single link inline, in that either the
first GBE link (first two ports) or the second GBE link (third and fourth ports) can be used, as illustrated
in the diagram above. The remaining pair of ports is unused.
