4. Optical connectors and cleaning
The fiber ends can be damaged by the insertion of contaminated connectors. Some types of customer
damage to connectors are not covered under warranty. The standard optical connector of optical transmitter
M0S212 is SC/APC.
Each fiber connector maybe polluted by dust or dirt in the operation process. Even very micro dust will
also affect the transmission quality. Dusty fiber optic connector will pollute other connected optic parts. If
optical receive power and output level of the receiver decline, you should clean and maintain fiber active
connector.
Always clean all the fiber optic connectors before setting.
Reel cleaners or prepackaged alcohol lint free wipes or swabs are the most convenient means of cleaning
optical connectors.
Fiber connectors should never be left uncovered.
Do not exceed the minimum bending radius when connecting cable to the system.
