PLC Optical Power Splitter

- Jul 31, 2018-

PLC  splitter is an optical splitter, also known as "non-wavelength selective optical branching device", which is used to realize the power splitter and redistribution function of specific band optical signals. Optical fiber splitter is mainly used for coupling, branching and distributing optical signals in optical network system. The optical fiber splitter can be used as an independent device in OLT nodes, optical distribution points and user access points, or in other local end distribution facilities, optical distribution points and user access points (integrated design or pluggable). Optical fiber splitter is one of the most important passive devices in optical fiber link. It is an optical fiber splitter with multiple input terminals and multiple output terminals, and M×N is commonly used to represent that a splitter has M input terminals and N output terminals. The optical fiber splitter used in optical fiber CATV system is generally 1×2, 1×3 and 1×N optical splitter composed of them.

Manufacturing technology of optical fiber splitter. According to the production process, fiber Splitter is divided into FBT Splitter and PLC Splitter. The fused bi-conical tap Splitter. Melting pull cone technology is two or more optical fiber tied together, and then in the pull cone machine melting stretch, and real-time monitoring of the change of the ratio of light splitting, light splitting ratio to meet the requirements after the end of the melting stretch, one end of an optical fiber (the rest cut off) as the input end, the other end for the multi-channel output end. At present, mature tapering technology can only be pulled below 1×4 at a time. Devices above 1×4 are connected with multiple 1×2 devices. Then the whole package in the divider box.

Planar optical waveguide technology USES semiconductor technology to make optical waveguide branch devices. The function of branching is completed on the chip, which can realize more than 1X32 branching on a chip. Then, the two ends of the chip are coupled to encapsulate multi-channel fiber array at input end and output end respectively.
