Polarization Maintaining Fiber

PMF-1550-B2

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

StockerYale’s PMF-1550-B2 is a polarization maintaining fiber designed for optimal performance in fiber optic interferometers, sensors, and telecommunication component applications. The fiber features an operating wavelength of 1550 nm and a beat length of < 4 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 interferometers
Voltage and current sensors
Connectivity between source laser and modulator
Laser pigtailing
Polarization-sensitive components
