The function of the optical distribution network

The function of the optical distribution network. The optical distribution network refers to part which provides the bidirectional optical transmission method in the light access network. From the network structure point of view, the optical distribution network is composed of fibers, fiber optical splitters and branches.

 

Fiber Distribution Terminal

 

At present, the device basic structure based on the GPON technology is similar to the existing PON. This basic structure is also composed of the optical line terminal (OLT), optical network terminal/optical network unit (ONT/ONU), optical distribution network (ODN) and the network management system. And the main function of the optical distribution network is to connect the OLT and ONT/ONU.

The o ptical fiber terminal box adopts the design of high density and large capacity. It has a nice appearance and it has the features that are reasonable distribution, easy to find, easy to manage, easy to install and good operability. The optical fiber terminal box can be divided into: 1x8, 1x12, 1x24 and 1x48 optical fiber terminal box.

The manufacturing process of the optical cable

The manufacturing process of fiber optical cable generally includes:   Firstly , is the selection of fiber optical cable. We should choose the fiber with excellent feature of transmission and the qualified tension.   Secondly , we dye the fiber. We identify the fiber cable with the standard chromatography. And the fiber cable must be not fade and migration in high temperature.   Thirdly is the secondary extrusion. We use the plastic with high elastic modules and low coefficient of linear expansion and extrude it into the pipe with a certain size.And we fill the fiber and the moisture-proof and waterproof gel into the pipe. Then we store it a few days (not less than two day).
