Using dustproof cap to protect the end-face.
Using an attenuator to prevent over saturating an optical receiver when the optical power is too high and ensures low bit error rates preventing damage to receiving fiber optic equipment.

Attenuator Application
Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver. Optical attenuator is widely used in CWDM&DWDM, CATV systems, data center networks, test equipment and other high power applications.
