1550 nm Polarization Maintaining Single-Mode Optical Fiber

Part Number: FS-PM-7811 Stock Number: 98-0400-1352-0

October 2001

Product Applications Interferometric Sensors

- Fiber Optic Gyroscopes High Coherence Light Transmission

Features and Benefits High numerical aperture design prevents signal loss under tight bends and preserves 

optical performance in miniature packaging applications and standard cable designs.

Stress-induced birefringence allows low loss transmission of polarized light with little



cross talk between fiber polarization modes.

Dual component fiber coating system offers stable polarization performance over a



wide temperature range.

Reduced fiber diameter allows high density fiber packaging.
