Polarization Maintaining Fiber-Based Components

PM Fiber-to-Fiber Isolators

DPM Photonics provides a large selection of Polarization Maintaining (PM) Fiber to Fiber Isolators. These devices can handle powers between 300 mW and 20W and have center opterating wavelengths ranging from 850 nm to 1550 nm. Standard pigtail fiber is Panda 980 or Panda 1550.

This product line is Telcordia qualified. Some Telcordia qualification data is provided (GR-1221-CORE, ISSUE 2) for a 1064 nm, polarization-maintaining fiber to fiber isolator with maximum power handling of 20W. Excellent product stability is observed, via minimal changes in key isolator parameters, over 2000 hours of damp heat testing (85C, 85% RH) and temperature cycling over 500 cycles.

If you do not see a standard PM isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths of operation or other specific need will be readily addressed.
