DEP Depolarizer General Photonics Datasheet

Product information "DEP Depolarizer"

1310, 1550 nm; IL 1.0 dB; DOP <5%; ER <0.5 dB; RL 55 dB

General Photonics’ DEP depolarizer module is a passive device (requiring no external power) that depolarizes laser output. The standard configuration can be used for coherence lengths less than 10 m. Custom units can be specified for coherence lengths of multiple kilometers.

The DEP polarizer is ideal for minimizing the polarization sensitivity of fiber optic sensor systems such as systems for quasi-distributed temperature and strain sensing based on fiber Bragg gratings (FBG), systems for distributed temperature and strain sensing based on Brillouin or Raman scattering and systems for distributed acoustic sensing based on Rayleigh scattering. It can also help to eliminate the effects of PDL or polarization sensitivity of optical components and instruments. Equally important, it can be used for depolarizing pump lasers to eliminate the polarization sensitivity of Raman amplifiers.

The DEP polarizer is packaged in a small (85 × 60 × 10 mm), rugged aluminium box, providing high performance and superb environmental stability. The internal structure and package size may be different depending on the coherence length or spectral width of the light signal to be depolarized. Contact AMS Technologies for an optimized configuration for your intended applications.
