This procedure verifies the span loss between two DWDM nodes using
CTC. You perform this procedure after a node or network modification has
occurred and you want to verify that the span loss between the nodes have
not changed.
A node provisioning plan prepared by Cisco MetroPlanner is required.

Complete the "DLP-G155 Verify Optical Span Loss Using CTC" task on page 9-3
using CTC. This task is faster than a span loss measurement using an optical time domain
reflectometer (OTDR) and does not require fibers to be removed. However, the resolution is not as
precise as an OTDR measurement.
