Star couplers with up to 32 ports have been possible using fused tapered fiber 3 db couplers.
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 splitters are used to divide the input optical fiber light at a certain ratio and send them to output parts.
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.
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.
Real world fiber optic splitters show uniform performance across the whole spectrum of interest from 1260 to 1600 nm.
Optical splitters are usually used in passive optical networks pons to distribute fiber to individual homes or businesses.
1 n fiber optic splitter loss ratio chart are given bellow.
In this tutorial we are going to talk about optical splitter loss testing with optical power meter and light source.
Optical coupler is an optical device that combines or splits power from optical fibers.
A typical split ratio in a pon application is 1 32 meaning one incoming fiber split into 32 outputs.
Optical splitter loss ratio 1 n.
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.
