You use optical couplers and splitters to split or join signals in fiber networks. These unassuming devices enable a single optical signal to be divided into multiple paths, making them indispensable for sharing. Find out more about how you can use optical splitters to simplify the process of expanding fiber optic networks, making it more efficient and cost-effective. It plays a vital role in optical fiber communication systems, especially in passive optical networks (PONs). 📄 What is an Optical Splitter? An Optical Splitter, also known as a beam splitter, is a passive. A fiber broadband provider typically determines and overall split ratio for the network, such as 1x32 or 1x64, and uses combinations of splitters to meet that ratio with each PON port.
