Optical fiber splitter is an optical fiber junction device that realizes the coupling, branching and distribution of optical signals in optical network system. It is a component of the EPON network, a passive device that connects the OLT and the ONU, and its function is to distribute downstream data and centralize upstream data.
An optical splitter distributes optical signals transmitted in one fiber to multiple fibers. There are a number of different distributions, 1 x 2,1 x N, or 2 x 4, M x N. The general architecture of FTTH is: OLT -- ODN -- ONU, in which the optical splitter is applied in the ODN to realize that multiple end users share a PON interface.
In PON structure, when the distribution of buildings is scattered and irregular, such as the distribution of villas, the distance is far away, and the user density is low, the centralized splitting method can make full use of resources and cover the surrounding area.
