Splitters and Couplers utilize precision technology to combine or distribute light from single/multiple inputs to single/multiple outputs. Most Couplers and Splitters are designed bi-directionally, enabling the same product to be used as acoupler or a splitter. Planar light wave circuit (PLC) splitter is a type of optical power management device that is fabricated using silica optical waveguide technology. It features small size, high reliability,wide operating wavelength range and good channel-to-channel uniformity, and is widely used in PON networks to realize optical signal power splitting. 4fiber provides whole series of 1xN and 2xN splitter products that are tailored for specific applications.
