PM Optical Switch

Polarization Maintaining Optical Switches


Fibermart Polarization-maintaining (PM) Optical switches are mostly used in the telecommunications, network technology, sensor and measurement technology. Fiber-MART.COM offers PM switches for all standard PM fibers with module, bentchtop, rack mount or mini packages.

These PM optical switch are available in different configurations – from 1x1 (on/off switches) to n x m (matrix switches) – making it possible to achieve configurations such as, for example, 1x2, 1x4, 1x8, 1x16, 1x32, 1x64, 2x2, or 2x4 pm optical switches. The Fibermart Polarization-maintaining optical switch works at 630nm, 780nm, 980nm, 1310nm or 1550nm center wavelengths.

  • Individual Test Report Included with Each pm optical switch (Click Here for a Sample Data Sheet)
  • Custom Wavelength, 1xN, 2xN configurations and Connector Options
  • Extinction Ratio (dB) ≥ 18dB, insertion loss IL typically between 0.4dB and 1.2dB

The Fibermart polarization maintaining optical switch controlled by TTL communication protocol. For the RS-232 or USB control version, click PM Fiber Switch (RS-232 or USB).

The insertion loss IL of PM switches typically lies between 0.4 dB and 1.2 dB, primarily depending on the type of fiber and the switch configuration. Extinction Ratio (dB) ≥ 18dB. The Fibermart switches can be delivered with any of standard fiber connector systems.
