60dB Variable Fiber Optic Attenuator
SM MM Collimator Variable Optical Attenuator With SC LC FC Connectors
Description
0.6~60dB SM MM Collimator Variable Optical Attenuator with SC LC FC Connectors manufactured by ANC International Co., Limited utilizes miniature collimator structures to achieve continuous, accurate and variable optical attenuation in a wide spectrum. It can achieve 0.6dB to 60dB attenuation with a precision of 0.1dB. This Collimator variable optical attenuator (VOA) is a fiber optic attenuator that is available in Single mode, Multimode 62.5 and Multimode 50µm. These attenuators can be terminated with any connector option including, SC, SC/APC, ST, ST/APC, FC, FC/APC, LC, LC/APC and E2000. This is useful tool for the optical components power adjustment and systems test.
