Single-Mode Variable Fiber Attenuator FSA-780S-PC
A single-mode variable fiber attenuator allows users to change signal attenuation manually as light passes through the device. JCOPTIX versions offer flexible, convenient adjustment and high stability, preventing optical damage from excessive intensity in communication systems and fiber test equipment. Wavelength coverage is 630-2050 nm. Three attenuation ranges are available: 0.9-50 dB, 1.3-50 dB, and 2.6-50 dB. FC/APC or FC/PC connectors are selectable. Maximum optical power options are 100 mW and 300 mW: 100 mW at 630 nm and 670 nm, and 300 mW at other wavelengths. JCOPTIX offers custom attenuators; contact technical support for assistance.
