Transponder Aggregator Without Wavelength Selector for Colorless and Directionless Multi-Degree ROADM Node
First Claim
1. A method for transponder optical channel selection of optical signals from a transponder aggregator, said method comprising the steps of:
- choosing wavelength division multiplexing channels to be dropped from a transponder aggregator receiving optical input signals;
splitting all dropped wavelength division multiplexing channels into at least one transponder having a coherent receiver and transmitter; and
tuning a local oscillator laser of said coherent receiver to a wavelength of one of said all dropped wavelength division multiplexing channels for selecting one of said all dropped wavelength division multiplexing channels.

Abstract
A method for transponder optical channel selection of optical signals from a transponder aggregator includes choosing wavelength division multiplexing channels to be dropped from a transponder aggregator receiving optical input signals, splitting all dropped wavelength division multiplexing channels into at least one transponder having a coherent receiver and transmitter, and tuning a local oscillator laser of the coherent receiver to a wavelength of one of the all dropped wavelength division multiplexing channels for selecting one of the all dropped wavelength division multiplexing channels.
