In light communication system, since the accidents such as fiber cut, equipment failure or optical connector extraction can lead to light
Power loss.On the one hand consider for personnel safety, it can be in an optical transmission section of main optical path under luminous power loss situation
Start APR (Automatic Power Reduction, power reduce automatically) and protect process, fiber link normally communicates certainly afterwards
Dynamic to restore, APR luminous powers are required to meet BSEN 60825-1-1994 and BSEN 60825-2-2000 standards.On the other hand for
System protection considers that APS can be generally added in optical transmission chain, and (Automatic Protection Switched fall automatically
Change protection), protection link is automatically switched to after active link breaks down, so as to ensure system stability.
Traditional APR/ALS (Automatic Laser Shutdown)) and APS be all based on optical signal suddenly lose cause
What luminous power was reduced and was triggered suddenly.Traditional APR and APS protections process is illustrated separately below.
APR protection systems shown in Figure 1, after A point cable breakouts, optical transmission signal is detected at receiving port R2
Loss of continuity (LOC-OTS), this may result in the reduction of T2 sending port output powers；It is similary to cause at receiving port R1 again
LOC-OTS so that at sending port T1 output power reduce.It is ensured that in this way in the light of A points to break down
Power is all in level of security.
APS protection systems shown in Figure 2, when A roads are broken down, such as disconnected fine or amplifier damage, A can be caused
The luminous power on road reduces, and when photoswitch control panel (OP plates) monitors that A, B two-way power difference reach threshold value, will start
Business is switched to protection channel B by service aisle A, ensure that the reliability and stability of business by APS pretection switch processes.
To sum up it will be seen that APR and APS processes are all based on optical signal, loss causes luminous power to reduce suddenly suddenly
And triggering, as long as fluctuation occurs for luminous power beyond threshold value i.e. meeting trigger protection process, and for the optical fiber of fiber link
Energy and optical signal transmission performance are simultaneously not concerned with, but optical fiber property and optical signal transmission performance can directly affect the reliable of communication system
Property, common carrier is more and more for optical-fiber network performance attention rate instantly, therefore, the luminous power lost suddenly based on optical signal
The network protections such as the APS and APR of variation monitoring cannot be met the requirements.
