The working principle of fiber optic splitters is based on the 1:N splitting principle. The splitting can be achieved through two main methods: parallel beam splitting and beam divergence splitting. Bandwidth is shared amongst customers in a PON, and the bandwidth received by a customer is not related to the power received at the optical network terminal (ONT) as long as the power is high enough so the ONT can operate. Splits are most commonly factors of 2, such as 1x2, 1x4, 1x8, 1x16, 1x32. Optical splitters, also known as fiber optic splitters, are integral components in fiber optic networks, enabling one fiber input to be divided into multiple outputs. 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. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network Terminals (ONTs) at users' homes, splitters eliminate the need for dedicated fibers to each residence—slashing infrastructure costs while scaling network reach. When an optical signal is transmitted in a single-mode fiber.
