Method for detecting wavelength usage conflicts in an optical network

摘要

A method of adding a transceiver including a transmitter and a receiver to an optical network. The transceiver is controlled to enable the receiver while maintaining the transmitter in a disabled state. The receiver detects a presence of an optical signal at a first wavelength. If an optical signal at the first wavelength is not present, the transmitter is enabled. Responsive to detection that an optical signal at the first wavelength is present: a feature of the optical signal, and a match condition between the detected feature and a predetermined feature are detected. The transmitter is enabled responsive to detection of the match condition.

1. A method of using a transmitter and a receiver in an optical network, the method comprising:
a) enabling the receiver while maintaining the transmitter in a disabled state; b) detecting, by the receiver, a presence of an optical signal at a first wavelength; c) responsive to detection that an optical signal at the first wavelength is not present, enabling the transmitter to transmit light; at the first wavelength; and d) responsive to detection that an optical signal at the first wavelength is present:
detecting a feature in overhead of the optical signal,detecting a match condition between the detected feature of the optical signal and a predetermined feature of the transmitter, andenabling the transmitter to transmit light responsive to detection of the match condition.
