Splitters used in a GPON system are passive (meaning they aren't powered), and bi-directional, allowing light to travel in both directions. They typically have connectors on the fanout side. Cost Efficiency: A single OLT port can serve 8–64 ONTs via a splitter, reducing the number of OLTs, fibers, and deployment labor needed. Splitters are essential when you want one fiber line from a central office (like an ISP's headend or data center) to serve multiple homes or businesses. Imagine a tree. 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. As XGS-PON continues to be adopted, some service. Optical splitters, encompassing FBT (Fused Biconical Taper) couplers and PLC (Planar Lightwave Circuit) splitters, are prevalent passive optical devices designed to divide fiber optic light into multiple segments based on a specified ratio.
