Protection system, method and apparatus for optical network

摘要

The invention discloses a system, a method and an apparatus for optical network protection. The system includes: an output control apparatus for obtaining protection mode information configured by a system and controlling an input signal to be output from a set line corresponding to said protection mode information; and a detection control apparatus for detecting powers of signals transmitted on an active line and on a standby line, if it is determined that the active line is abnormal and the standby line is normal according to detection results, then controlling the input signal to be output from a protection line corresponding to the protection mode information; if it is determined that the active line is normal, or that the active line and the standby line are abnormal according to the detection result, then controlling the input signal to be output from a set line corresponding to the protection mode information.

主权项

1. A system for configuring optical network protection mode, comprising:
an output control apparatus, which is configured to: obtain protection mode information configured by a system and control an input signal to be output from a set line corresponding to said protection mode information; and a detection control apparatus, which is configured to: obtain the protection mode information configured by the system and detect powers of signals transmitted on an active line and on a standby line respectively, and control said input signal to be output from a protection line corresponding to said protection mode information if that said active line is abnormal and said standby line is normal is determined according to a detection result; control said input signal to be output from a set line corresponding to the protection mode information if that said active line is normal is determined or that said active line and said standby line are abnormal according to the detection result is determined; thereby the optical network protection mode can be dynamically configured.
