Planar Lightwave Circuit Splitter Details
It features a PLC chip at its core, which is responsible for the precise splitting of optical signals. The input side has a single fiber connector, typically of a standard type like SC, which is used to receive the incoming optical signal.
On the output side, there are five fiber connectors, also commonly SC type. These output fibers are designed to carry the split optical signals. The split ratio of 60%/40% means that when an optical signal enters the splitter, approximately 60% of the optical power is directed to one output, and the remaining 40% is distributed among the other four outputs (or in a specific configuration as per design).
The fibers used are usually single-mode fibers, ensuring low loss and high-speed transmission over long distances, which is essential for applications in telecommunications networks, such as passive optical networks (PONs), where signals need to be split to multiple users efficiently. The connectors are designed for easy and secure connection, minimizing signal loss at the connection points.
In terms of performance, this splitter offers low insertion loss, meaning only a small amount of the optical signal is lost during the splitting process, and high uniformity among the output signals (to the extent possible given the unbalanced ratio), which is crucial for maintaining signal integrity in fiber-optic systems.
