Connectors & Cables
These polarization-maintaining fiber optic patch cables are terminated on both ends with high-quality, narrow key, ceramic FC/PC connectors, featuring high-quality polish with a typical return loss of 50 dB. Each cable is individually tested to ensure the specified extinction ratio and insertion loss at fiber-to-fiber junctions. Each patch cable includes two protective caps that shield the ferrule ends from dust and other hazards. Each cable comes with a mating connector adaptor for ease of use. Fiber Optic Connector Power Handling Thresholds vs Wavelength The line below is an empirical approximate optical power handling for ceramic ferrule connectors vs wavelengths. Operating above this level, the fiber connector butt coupling becomes less reliable.

Application context
Application guidance is tied to the configured wavelength, fiber interface and optical-budget fields for this family.
Polarization-Maintaining Fiber Optical Patch Cable - PM780: Laboratory optical integration depends on preserving the optical budget through the complete path. The 780nm wavelength specification sets source and detector compatibility. The fiber/interface entry (1m, 5m, 12m) must match the connected components.

Technical FAQ
Fiber Length: 1m, 5m, 12m · Fiber Type: PM780. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 780nm. Check the Connectors & Cables passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
