8. Cleaning & Maintenance
Each fiber connector can become contaminated by dust or dirt in the operation process, which can result in increased optical
link loss, or a degraded carrier-to-noise ratio. If you find that the optical receive power or RF output level of the optical receiver
has declined, you should clean and maintain the fiber optic connector. The clean methods are recommended below:
a) For safety reasons, the AC power to the transmitter should be turned off first.
b) Carefully unplug or unscrew the active fiber connector from the adapter, while being careful to avoid aiming the fiber
connector at any human body or eye.
c) Use a lint-free fiber optic wipe saturated with alcohol to clean the connector carefully. Once finished, still wait 1 to 2
minutes until active connector surface is dry in the air.
d) When the cleaned optical active connector is reconnected to the adapter, please do not over-tighten or force the
connector, to avoid damage to the ceramic ferrule.
e) The fiber connector should be cleaned on both ends. If optical power is still low after clean, cleaning the other end
of the fiber is recommended. If the optical power is still low after cleaning both ends, it is recommended that you
clean the inner adaptor.
f) Use compressed air or a lint-free wipe to wash the adapter carefully. When using compressed air, aim the nozzle at
the ceramic ferrule of the adaptor, cleaning the ferrule with compressed air.
NOTES:
1. Avoid aiming the optical output or fiber connector at the human body or eyes.
2. Assemble the fiber adaptor gently and carefully to prevent damage to the ceramic ferrule inside the adapter.
