Polarization Maintaining Fiber

PMF-RC-820-B1

High birefringence
Low attenuation
Bow-tie stress structure design
Low bending induced attenuation
Superior polarization maintaining properties
Excellent product consistency

StockerYale’s PMF-RC-820-B1 is a reduced clad polarization maintaining fiber designed for optimal performance in fiber optic gyroscopes, sensors, and telecommunication component applications. The reduced 80 µm cladding is engineered for applications requiring a tight bend radius with minimal bend loss and features an operating wavelength of 820 nm and a beat length of < 1.8 mm. Its bow-tie stress structure provides high birefringence while maintaining excellent spliceability to existing PM and single-mode fibers. We can also custom design this fiber to meet your specific design requirements.

Applications:

Fiber optic gyroscopes (FOGs)
Fiber optic sensors
Connectivity between source laser and modulator
Laser pigtailing
Polarization-sensitive components
