Title:
AUTOMATIC OPTICAL POWER REDUCTION METHOD AND APPARATUS FOR MULTI-CHANNEL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/058341
Kind Code:
A1
Abstract:
Provided are an automatic optical power reduction method and apparatus for a multi-channel system. The method comprises: when a first multi-channel interface cannot receive an optical signal sent by a second multi-channel interface, only opening a first specific channel in a direction from the first multi-channel interface to the second multi-channel interface, and closing the other channels in the direction from the first multi-channel interface to the second multi-channel interface, so as to instruct the second multi-channel interface to only open a second specific channel in a direction from the second multi-channel interface to the first multi-channel interface and close the other channels in the direction from the second multi-channel interface to the first multi-channel interface; and when the first multi-channel interface receives the optical signal from the second particular channel, opening all the channels in the direction from the first multi-channel interface to the second multi-channel interface, so as to instruct the second multi-channel interface to open all the channels in the direction from the second multi-channel interface to the first multi-channel interface. The present solution solves a security problem that the laser power of a multi-channel system exceeds a standard, and also realizes energy saving.
