Optical network communication system with optical line terminal transceiver and method of operation thereof

Abstract

A method of operation of an optical network communication system including: providing a planar lightwave circuit including: connecting 2×2 single-mode optical couplers in an array for forming a 1×N single-mode optical splitter/combiner, and routing harvesting ports to an optical line terminal receiver for collecting harvested-light, from two or more of the harvesting ports, in the optical line terminal receiver wherein one of more of the harvesting ports is from the 2×2 single-mode optical couplers; transmitting to an optical network unit through the planar lightwave circuit at a first wavelength; and interpreting a response from the optical network unit at a second wavelength through the harvested-light.

What is claimed is: 
     
         1 . A planar lightwave circuit comprising:
 2×2 single-mode optical couplers coupled in an array to form a 1×N single-mode optical splitter/combiner with two or more harvesting ports from uncommitted ports of the 2×2 single-mode optical couplers, where N is greater than 2, each of two or more of the 2×2 single-mode optical couplers includes a port uncommitted and available to become one of the harvesting ports; and
 a waveguide configured to form a single composite harvesting port efficiently routing a combined harvested optical signal.
