Example Shelf Configurations and Topologies

The requirements of a particular topology determine what components must be used and how they are

interconnected. This chapter provides examples of shelf configurations and optical power budget

calculations specific to each of the main types of protection schemes supported by the Cisco ONS 15530,

and examples of supported topologies. This chapter contains the following major sections:

• Shelf Configurations, page 6-1

• Cisco ONS 15530 Topologies, page 6-25

• Cisco ONS 15530 and Cisco ONS 15540 Mixed Topologies, page 6-32

• Cisco ONS 15530 and Cisco ONS 15540 Collocated Topologies, page 6-33
