Optical cable transfer boxes, also called street cabinets, are generally placed on the backbone cable for the disagreement of optical cables. It is a passive device and functions similarly to the original copper cable transfer box, except that the large number of optical cables pass through. After the cable transfer box, several small logarithmic optical cables are divided into different directions. Of course, this function cable connector box can also be realized, but the difference is that the optical cable transfer box can realize the jump of the optical cable, and can also be used for testing and maintenance. . In general, the cable transfer box is the dividing point for the feeder cable and the distribution cable.
Optical splitters, popularly speaking, are used to broadcast a light beam in a core through a physical channel to multiple cores. The purpose is to improve the utilization efficiency of the trunk fiber and reduce the logarithm of the trunk fiber.
The second split, the general splitter has 1 point 2, 1 point 4, 1 point 8, 1 point 16, 1 point 32, 1 point 64, also 1 point 128; if the user concentrates, in a light path, can only install A beam splitter, called 1 split, if the user is distributed more dispersed, you can install two splitters on a single optical path, such as 1 minute 2 and then 1 minute 32. In this case, the actual maximum split ratio is still 1 minute 64, but It is possible to reduce the number of cores of the optical cable or improve the utilization of the core in the line between the two optical splitters.
The optical splitter does not necessarily need to be placed in the light box. It can be placed according to the actual situation. However, the optical splitter is currently mainly applied to splitting light from the main optical fiber, so most optical splitters are placed in the optical box, and the optical transport box has good mechanical properties and can play a good protection role.
