1550 Fiber Optic Coupler
The F-PMC-1550-50 Polarization Maintaining (PM) Fiber Optic Coupler utilizes evanescent wave coupling to provide a fixed 50/50 ratio 2x2 coupler, with high polarization extinction ratio (PER) and low insertion loss for the 1550 nm wavelength. These couplers are available with a coupling ratio of 50:50, 75:25, 90:10, 99:1, or 99. 1x2 Single Mode (SM) Fiber Splitters/Couplers allow for a single fiber input to be split into two outputs or for multiple inputs to be combined into one output.

Single-mode fiber 1550 loss
1550 nm operates in the low-loss window of SMF, with typical attenuation around 0. 25 dB/km, significantly lower than 850 nm multimode or 1310 nm single-mode systems. This property allows optical signals to travel longer distances before requiring amplification or regeneration. But there are benefits to making it standard practice to test ALL fiberoptic cable assemblies at both 1310 and 1550: the Insertion Loss variation between 1310nm and 1550nm test wavelengths can be very helpful in identifying serious problems with the product and / or process. All single mode fibers work very similarly at any wavelength, and if your fiber optic components are properly constructed using quality materials and good technique, then the insertion loss value for any given fiber optic connector when tested on a 1310 or 1550 Should be very similar. Optical fibers (usually silica-based glass) exhibit attenuation (loss) that varies strongly with wavelength.
