Distributed Raman amplifier systems

摘要

A distributed Raman amplifier system is disclosed. Distributed Raman amplifier systems can include a spool of fiber disposed between a distributed Raman amplifier and local or proximate optical point-loss sources, a carrier hotel for example. The spool of fiber has a fiber of sufficient length to offset aggregated losses, which prevents the distributed Raman amplifier from shutting down while also allowing the distributed Raman amplifier to achieve entitled gain by pumping the fiber in the spool.

主权项

1. A distributed Raman amplifier system comprising:
a distributed Raman amplifier configured to detect observed optical losses of a transmission line via a pulse and to pump the transmission line when the observed optical losses satisfy optical threshold criteria; and a spool of fiber disposed between and coupled with the distributed Raman amplifier and a set of optical point-loss sources, the spool having sufficient fiber length to offset aggregated losses from the set of optical point-loss sources by causing the observed optical losses observed by the distributed Raman amplifier to satisfy the optical threshold criteria.
