Applications of Fiber Optic Splitter

 

  In today’s optical network topologies, the advent of fiber optic splitter is significant in helping users maximum the performance of optical network circuits. Last time, we introduced the classification of fiber optic splitter, and today, we are going to discuss a more realistic topic – the applications of fiber optic splitter.

 

How does a fiber optic splitter work?

 

As for the working principle of fiber optic splitter, it can be generally described in the following way. When the light signal transmits in a single-mode fiber, the light energy can not entirely concentrate in the fiber core. A small amount of energy will be spread through the cladding of fiber. That is to say, if two fibers are close enough to each other, the transmitting light in an optical fiber can enter into another optical fiber. Therefore, the reallocation technique of optical signal can be achieved in multiple fibers. And this is how fiber optic splitter comes into being.

 

Main applications of fiber optic splitter.

 

1) Passive monitoring application of fiber optic splitter is used for the maintenance of long-haul network, cable TV ATM circuit or local area/metro area network. The splitter taps into a small percentage of optical traffic. Majority of the signal arrives its destination, but a small percentage is directed to a local access port. The application can be done by manual operation for troubleshooting purposes or by connecting the splitter to a network monitoring system for ongoing maintenance and performance assessment.

2) Fiber optic splitter can also be used for FTTX / PON application. This enables to reduce the physical fiber usage or the basic quantity of required fibers. A single fiber can be split into many branches to support multiple end users. The strain on the fiber backbone can be greatly decreased through the application.
