Method and device for adjusting a laser in an optical network

摘要

A method and a device for adjusting a laser in an optical network. At least one alive message is transmitted from a first optical component towards a second optical component. A confirmation message is transmitted from the second optical component to the first optical component determining the wavelength of the laser to be used based on the alive message received by the second optical component. Furthermore, an optical communication system is provided with an optical element.

1. A method for adjusting a laser of a first optical component in an optical network, the method which comprises:
transmitting several alive messages at different wavelengths from the first optical component towards a second optical component; subsequently conveying at least one response message from the second optical component towards the first optical component, the at least one response message indicating that at least some of the several transmitted alive messages at different wavelengths were heard by the second optical component; determining an acceptance range based on the at least one response message indicating that the at least some of the alive messages at the different wavelengths were heard by the second optical component, said acceptance range denoting a wavelength range that allows the second optical component to receive the alive messages; and choosing a wavelength for the laser of the first optical component within this acceptance range; wherein the wavelength chosen is a wavelength in or around the middle of said acceptance range.
