Coherent Polarization Maintaining Telco fibers are designed for today’s most advanced networks. Optimized for use at 1310 nm, these fibers are used in all PM applications for data and telecom. Coherent has applied its unique manufacturing facility and capabilities to this product area and has established leading optical, mechanical and geometrical tolerances. The bend insensitive versions of our fibers offer lowest bend loss and extinction ratios at small bend diameters enabling our customers to reduce package sizes. Available in either 250 or 400 micron coating diameters and prooftested to 200 kpsi, Coherent PM fibers will meet the demands of all current and future applications.
