Fiber Optic Splitter Loss

In order to conserve the power budget of a pon system the insertion loss from the splitter needs to be minimized.

Fiber optic splitter loss.

Optical coupler is an optical device that combines or splits power from optical fibers. Star couplers with up to 32 ports have been possible using fused tapered fiber 3 db couplers. In this tutorial we are going to talk about optical splitter loss testing with optical power meter and light source. 1 n fiber optic splitter loss ratio chart are given bellow.

Real world fiber optic splitters show uniform performance across the whole spectrum of interest from 1260 to 1600 nm. A typical split ratio in a pon application is 1 32 meaning one incoming fiber split into 32 outputs. There is something different between testing an optical splitter and a patch cable although both of them use optical power meter and light source to test. Optical splitter loss ratio 1 n.

Optical splitters are usually used in passive optical networks pons to distribute fiber to individual homes or businesses. Advantages are the low loss easy coupling with the optical fiber transmission line and no polarization dependent loss. Thus the loss budget of the cable plant is a major factor in the power budget of the fiber optic link and is what one calculates to compare against tested. The cable plant loss budget is a function of the losses of the components in the cable plant fiber connectors and splices plus any passive optical components like splitters in pons.
