0-20dB 850nm Multimode Mini MEMS Variable Optical Attenuator

The FT-850-10 from F-tone Networks is a multimode variable optical attenuator built on electrostatic MEMS technology, designed for power control in multimode laser systems. A movable mirror on the silicon chip attenuates the input beam by steering it onto the output fiber, with attenuation set by the applied voltage. It covers 850 and 1310 nm bands over 50/125 or 62.5/125 multimode fiber, with an attenuation range of 0 to 20 dB. Maximum insertion loss is 0.8 dB, return loss stays above 35 dB, and response time stays within 5 ms. The device handles up to 500 mW optical power in a hermetically sealed 28 x Phi5.4 mm package, operating from -5 to 70 degrees C with 10 mW power consumption.
