Polarization-Maintaining Variable Fiber Attenuator FSA-780P-PC
The polarization-maintaining variable fiber attenuator combines PM fiber and micro-optics. JCOPTIX versions provide flexible, convenient manual adjustment and high stability for systems containing PM components or requiring polarization maintenance. The wavelength range is 630-2050 nm. Three attenuation ranges are available: 0.9-50 dB, 1.3-50 dB, and 2.6-50 dB, with an extinction ratio range of 14-16 dB. FC/APC or FC/PC connectors are selectable. Maximum optical power ranges from 100 mW to 300 mW: at 630 nm and 670 nm it is 100 mW, and at other wavelengths it is 300 mW. JCOPTIX offers custom attenuators; contact technical support for assistance.
