NPMC – NoTail Polarization Maintaining Coupler
DESCRIPTION
The NoTail Polarization Maintaining Filter Coupler can either split the light from an input PM fiber between 2 output PM fibers, or can combine light signals from 2 PM input fibers into a single PM output fiber. The device can be used to split high power linearly polarized light into multiple paths without perturbing the linear state of polarization (SOP). It can also be used as a power tap to monitor signal power in a PM fiber system without disturbing the linear SOP of the light propagating in the PM fiber.
FEATURES
Split ratios from 1 to 50%
Low insertion loss and back reflection
Rugged design
APPLICATIONS
Power sharing in PM systems
Power monitoring in PM systems
