Fiber Optic Splitter Loss

Optical splitter loss ratio 1 n.

Fiber optic splitter loss.

Optical splitters are usually used in passive optical networks pons to distribute fiber to individual homes or businesses. A typical split ratio in a pon application is 1 32 meaning one incoming fiber split into 32 outputs. 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. 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.

The optical insertion loss is the loss of an optical signal resulting from the insertion of a component such as connector or splice in an optical fiber system. 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. The use of optical splitters in pon allows the service provider to conserve fibers in the backbone essentially using one fiber to feed as many as 64 end users.

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. 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. Fiber optic splitters are used to divide the input optical fiber light at a certain ratio and send them to output parts.
