Fiber Optic Splitter “PLC Splitter” is a passive optical splitter based on optical semiconductor technology. A typical PLC splitter consists of a PLC chip along with input and output arrays, the number of which depends on the split ratio, splitters are used to evenly divide one or two optical signals into multiple optical signals, such as 1×2 to 64 or 2×2 to 64 split ratios, and commonly used in the FTTx Networks
