PM 1×2 Optical Switch
This 1×2 Polarization Maintaining Optical Switch provides low insertion loss, high channel isolation, and reliable performance with an epoxy-free optical path. Designed for a wide wavelength range including 1310 nm and 1550 nm, it offers both latching and non-latching operation modes with low polarization-dependent loss and high stability.
Ideal for optical network protection, signal routing, configurable add/drop modules, and test systems, the switch ensures consistent operation across extended temperature ranges. Its compact design and cost-effective performance make it suitable for various telecommunication and sensing applications. Custom configurations including wavelength, fiber type, connector style, and operating voltage are available to meet specific system requirements.
