PM14XX Polarization-Maintaining Fiber PM14xxB-XP
Coherent/Nufern polarization-maintaining telecommunications (Telco) fibers are designed for today's most advanced network applications, with operation optimized for the 1400-1500nm band. They support data transmission and telecommunications networks in all-polarization-maintaining (all-PM) systems. Coherent/Nufern uses proprietary manufacturing processes and equipment to produce high-performance PM fibers, fundamentally improving optical performance, mechanical performance, and geometric tolerances compared with similar products. Bend-insensitive PM fibers provide minimal bend loss and a high polarization extinction ratio at small bend radii, helping reduce device and product package sizes. The series offers coating diameters of 250um or 400um and proof-test levels up to 200kpsi. Coherent/Nufern PM fibers are intended to meet current and future application requirements.
