MFSW-1X2 optical switch type single mode optical switch module

MFSW-1X2 optical switch type single mode optical switch module

The MFSW-1X2 is a compact, single-mode MEMS optical switch module designed for reliable and low-loss light path switching. It features low insertion loss (≤1.0 dB), high channel isolation (≥50 dB), and fast switching time (≤30 ms), making it suitable for a wide operating wavelength range from 1260 nm to 1650 nm. With dual control interfaces (UART and parallel TTL) and a durable design supporting over 10 billion cycles, this module is ideal for use in optical monitoring systems, LANs, multi-point sensing, and automated test equipment. It operates on a single 5V DC supply and is offered with FC/PC connectors for easy integration.
