Smart Product Number: PM14XXC-HP
14xx 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.
