Single Link: Receive-only Topology

92964

In this topology, an external optical splitter resides physically on the GBE link between the subscriber side and the network side. The external splitter is connected to the SCE 1000 via Rx links only.

In this topology, the traffic passes through the external splitter, which splits traffic to the SCE 1000. The SCE 1000, therefore, is in receive-only topology, having only traffic monitoring capabilities.

Note Receive-only topologies can also be implemented using a switch. Such a switch must support SPAN functionality that includes separation between ingress and egress traffic and multiple SPAN-ports destinations.
