0-40dB Single-Channel Standard MEMS Variable Optical Attenuator

The FT-764 is a standard single-channel MEMS variable optical attenuator built for power control and channel management in fiber networks. It operates across 1530-1610 nm (C+L band) with continuous attenuation adjustment over a 0-40 dB range, driven by 5.2 V or 15 V. Insertion loss is limited to 0.7 dB maximum (0.5 dB typical) excluding connectors, return loss is at least 55 dB, and PMD stays within 0.1 ps. The FT-764 switches in 2 ms or less (1 ms typical), handles 300 mW of optical power and consumes no more than 2 mW, suiting instrumentation and receiver protection duties.
