PM 2×2 Optical Switch
This Polarization-Maintaining (PM) 2×2 Optical Switch provides low insertion loss, high channel isolation, and reliable bidirectional optical path switching with excellent polarization stability. Designed for operation in the 1310 nm and 1550 nm wavelength windows, it features an epoxy-free optical path and supports both latching and non-latching operation modes for flexible system integration.
Ideal for optical network protection, signal routing, configurable add/drop modules, and test systems, the switch ensures high repeatability and long-term reliability across extended operating temperatures. Its compact mechanical design and customizable options including fiber type, connector style, and operating voltage enable seamless adaptation to diverse optical system requirements.
