Couplers, Splitters & Combiners

1×4 Single Mode Fiber Optic Fused Coupler/Splitter

This FC Series fiber optic coupler provides us with monolithically integrated 1×4 function in a compact format. It features good uniformity, low excess loss, and very low polarization sensitivity. The device is ideal for splitting or combining light with exceptional performance over a wide wavelength range. Couplers are highly efficient in splitting light with little loss, about 0.2dB per joint, but incur significant losses when combining lights; for example, a 50/50 coupler produces a 50% loss to each beam when combined.

Integration and compatibility

Use these checks to connect 1×4 Single Mode Fiber Optic Fused Coupler/Splitter to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.

Optical interface and fiber: Fiber Type: SM28, SM1950, PM1550, PM980, PM850, PM400 · Fiber Cover: 900μm; Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength and loss budget: Wavelength: 1060, 1310, 1550, 980, 1310&1550, 1310/1410/1550, Special; Check the Couplers, Splitters & Combiners passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
