This device allows a single optical signal to be distributed across 32 separate fiber lines, making it a vital element in passive optical networks (PON), fiber-to-the-home (FTTH) systems, and other broadband applications. 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. This guide. An optical splitter is a crucial passive fiber optic device that splits and combines optical signals. Instead of running separate cables for each user or device, a central piece of equipment—called an Optical Line Terminal (OLT) —sends data down the line to multiple Optical Network Terminals. In general, when the distance between the cores of two optical fibers is close enough, the optical signal transmitted in one optical fiber can enter the other optical fiber, that is, the optical signal can be redistributed in the two optical fibers, which is exactly the origin of the optical.
