Options

Bend insensitive and low loss for minimum power consumption and longest coil lengths 

Minimal crosstalk due to high birefringence, and low mode field perturbation along length 

Low Tg coating minimizes stress induced birefringence to reduce crosstalk variation over a wide temperature range (-55°C to 105°C) 

Very high fatigue failure resistance 

Continuous lengths up to 5 km for high precision gyros 

Standard formats as small as 40 μm clad/90μm coating for maximum length on a small coil diameter 

Coating tolerances as low as 2 μm for repeatable fiber turns per coil layer 

Polarization or single mode designs 

Radiation hardened and radiation resistant varieties
