Fiber optic splitter

Fiber optic splitter plays an important role in FTTH networks by allowing a single PON network interface to be shared among many subscribers. Splitters contain no electronics and use no power. They are the network elements that put the passive in Passive Optical Network and are available in a variety of split ratios, including 1:8, 1:16, and 1:32.

A PLC fiber splitter is made with techniques much like those to manufacture semiconductors, PLC splitters are very compact size, and Environmental & mechanical stable, it has Wide operating wavelength and Wide operating temperature.

A Fused Biconical Taper (FBT) splitter is made by wrapping two fiber cores together, putting tension on the optical fibers, and then heating the junction until the two fibers are tapered from the tension and fused together. FBT coupler attenuation is higher than the attenuation from PLC splitters.

Fiber optic splitters can be terminated with different kinds of fiber optic connectors, the main package could be box type or stainless tube type, one is usually used with 2mm or 3mm outer diameter cable, the other is usually used with 0.9mm outer diameter cables.
