How to use optical splitter to deal with the problem that sig optical power of detect line is low

Publication Date:  2012-11-05 Views:  67 Downloads:  0
Issue Description
Sig often need to detect line traffic, through the optical splitting or mirroring way, send the flow to the Sig interface board, but if the optical power between the routers is low or in a critical value before optical splitting, increase splitting of passive optical splitter, will further reduce the line optical power, leading to port of two ends router down or appear a lot of error message.
Alarm Information
Handling Process
1. Can use active optical splitter having optical power amplification function, usually use the device of Wuhan Guanxun company.
2. Replace optical module of routers, increase device luminous intensity, such as replace 850 multi-mode to be 2km single-mode module, or replace 10 km single-mode optical module to be 30 kilometers or 50 kilometers single-mode optical module. When replace the optical module to enhance luminous power, must pay attention to the light intensity of peer end device is at the normal range at the same time. If beyond the range, need to consider to increase the optical attenuator.
