Neptec’s Special Polarization Maintaining (PM) Cables are engineered for low insertion loss and high extinction ratio. Customizations are available for single fiber and MULTI-FIBER configurations to meet specific application needs at non-standard wavelengths and core sizes (3um, 5um, 7um, etc.).

Our MULTI-FIBER PM cables are able to meet ≤ 3° stress rod angular tolerance per channel, in 12 and 16 fiber MT configurations.

We specialize in building assemblies and breakouts for applications demanding reduced cladding fibers down to 140um coating fibers.
