Commonly Used Optical Splitter Splitting Ratios

Commonly Used Optical Splitter Splitting Ratios

Power splitters (also commonly called "optical splitters") are devices that divide an optical signal into multiple, equal-intensity output signals. The split ratios are usually even, like 1:2, 1:4, 1:8, and up to 1:32. 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. The split ratio and insertion loss are two key parameters defining their performance.
