ASSEMBLIES AND METHODS FOR MANAGING SPECTRAL HOLE BURNING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17956900 titled 'ASSEMBLIES AND METHODS FOR MANAGING SPECTRAL HOLE BURNING

Simplified Explanation

The patent application describes a system and method for managing spectral hole burning (SHB) effect in an optical transport network (OTN) link using an automatic gain control (AGC) circuit in the amplification assembly. The method involves monitoring the input power of the incoming signal and adjusting the pump power variable attenuator (PVOA) to attenuate pump power when the input power is below a certain threshold.

Original Abstract Submitted

System and method for managing spectral hole burning (SHB) effect in an optical transport network (OTN) link. The method is performed by an automatic gain control (AGC) circuit of an amplification assembly of the OTN link. The method comprises determining, via a first photodetector communicatively connected to the AGC circuit, an input power of an income signal and, in response to the input power being less than a predetermined portion of a full-loading signal power, causing a pump power variable attenuator (PVOA) of the amplification assembly to attenuate pump power from a pump source, the PVOA being disposed optically intermediate a first doped fiber and a second doped fiber of the amplification assembly.
