Polarization-maintaining single-mode optical fiber

Description

Polarization-maintaining single-mode optical fiber with a germanium-doped silica core, fluorophosphosilicate isolating cladding and borogermanosilicate elliptical cladding in acrylate coating suitable for operation in the spectral range from 800 to 1600 nm.

Field of application:

  • Interferometric fiber optic sensors, including small-sized gyroscopes (PM40-810 and PM40-1310) and sensors using fiber Bragg gratings (PM125-1550PS)
  • Infocommunication systems and technologies
