NuPANDA Flyer

980 nm Polarization Maintaining Low Loss Coupler Fiber

Nufern’s broad line of PM fibers now includes PM980C-HP & PM14XXC-HP coupler fibers. Components designed with these new coupler fibers exhibit insertion losses up to one order of magnitude better than was previously possible. These fibers also demonstrate superior polarization control in coupler applications, resulting in increased system and network efficiencies.

Applications
Couplers and combiners Pump combiners Raman gain modules

Features & Benefits
Dramatically reduced insertion loss — Lower system cost High proof test (200kpsi) — Low risk of mechanical handling failure High fatigue failure resistance — Longest service life
