Abstract
A shared OTDR resource is disclosed that utilizes a combination of a pluggable OTDR and incorporated 1×N optical switch to allow for OTDR measurement and monitoring functionality to be shared between a plurality of N separate optical fibers that are used as communication paths between a pair of optical nodes (for example, a plurality of individual fiber spans used to interconnect a pair of data centers). The capability to maintain the OTDR functionality within a small form factor pluggable housing (e.g., QSFP, OSFP, or the like) in combination with the switch results in a shared OTDR resource that remains pluggable, and allows for increased flexibility in how this resource is shared among the various fibers.
