Cisco ONS 15530 Topologies
Point-to-Point Topologies
The Cisco ONS 15530 supports point-to-point topologies, with or without signal protection. A single
shelf supports up to four protected channels and up to eight unprotected channels. To supports more
channels, multiple shelf nodes can be used.
Use following criteria to determine the equipment needed for a point-to-point topology:
• Distance between nodes
• Potential topology changes in the future (such as migration to a ring)
• Presence of OSC
Unprotected Point-to-Point Topology
Figure 6-44 shows an example of an unprotected point-to-point topology between two Cisco ONS 15530
shelves.
