The F-PMC Series Polarization Maintaining (PM) Fiber Optic Couplers utilize evanescent wave coupling to provide a fixed ratio 2x2 coupler, with high polarization extinction ratio (PER) and low insertion loss.
These couplers enjoy inherent advantages because there is no deformation in the wave-guide cores. Furthermore, since the two Panda fiber halves are placed in direct contact with each other, these PM fiber couplers are more resistant to aging and environmental effects.
The F-PMC comes in a small, specially designed silicone rubber package that allows low stress contact of the fiber halves over a broad range of temperatures. Several different wavelength versions are available in 1/99, 10/90 or 50/50 coupling ratios. All the couplers have standard 1m pigtails and FC/APC connectors.
