Features
PM (Polarization-maintaining) MOSW-1X4-15-PM-09-05-03A-M1
1X4 PM MEMS optical switch，module packaging，5V driving voltage，1550nm，Corning PM1550 fiber 0.9mm loose tube,0.5m length，input output FC/APC connector 54.1*13.7*24.7mm
MEMS 1xN optical switch is based on micro-electro-mechanical system technology. It allows channel selection between an input fiber and up to N output fibers by rotating the MEMS mirror.
The switch is bi-directional and can also be used as a Nx1 selector switch. The optical switch offers highly reliable, durable, long-life operation in a compact package.

Optical Route
The mems optical 1x128 switch is a non-locking product. When the voltage is removed, the mirror returns to the initial position and the input is uncoupled to any output channel. The principle of optical path switching is shown in figure below.
