With a central splitter and fiber to each user configuration, there is flexibility to use each OLT port more efficiently, adding new OLT ports only when needed, and when every customer has a dedicated fiber, the CO can even support several ISPs (Internet Service Providers) by.

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. 1x32 splits were common in North America for G-PON architectures. As XGS-PON continues to be adopted, some service. A fiber optic splitter is a passive optical component that divides a single incoming optical signal into two or more outgoing signals, or combines multiple incoming signals into one. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. Rather than telling you how to design a FTTH network, we will illustrate some of the different network architectures, construction methods, etc. possible, then offer options that may work for your network and stimulate your design processes. This reduces the cost of the system substantially by sharing one set of electronics and an expensive laser with up to 32 homes.
