Fixed Fiber Optic Attenuator Singlemode 

FC Female to Male and Fixed Fiber Optic Attenuator Singlemode / Multimode 1dB 3dB 5dB 10dB LC SC ST FC Optical attenuators are passive device commonly used in fiber-optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. Sharp bends stress optic fibers and can cause losses. If a received signal is too strong a temporary fix is to wrap the cable around a pencil until the desired level of attenuation is achieved.  However, such arrangements are unreliable, since the stressed fiber tends to break over time.
