What does a Fiber Optic Distribution Box consist of?

The fiber optic distribution box is a separate line for users to enjoy, and it is divided into two groups of 8 lines in the network cable to transmit data. Therefore, it does not affect the speed and bandwidth of the user’s Internet access.

This is fundamentally different in transmission from the splitter connectors that are generally repurchased from outside. Therefore, the distribution box does not cause the users connected to the same pair of splitters can not access each other.

Fiber distribution boxes are used in pairs. A pair of distribution boxes are made up of two optical fiber cable distribution boxes.

A fiber optic termination box consists of two crystal heads and a module, which are connected to the module via a twisted pair cable. One of the crystal heads is lined up with 4 wires, blue and blue-white, brown-white and brown, in slots 1, 2, 3, and 6 of the crystal head.

The other crystal head is lined up with 4 wires, green-white, green, orange-white, and orange, in slots 1, 2, 3, and 6 of the crystal head. The other pair of DP boxes is done similarly.

How to use a Fiber Optic Distribution Box?

You need one distribution box fiber optic for the subscriber side (dormitory) and one for the switch side. If both ends of the network cable are crystal-tipped, you connect the two crystal-tipped ends to the two modules of the fiber distribution box.

Generally, a more extended splitter is placed at the user end, and a shorter splitter is placed at the switch end. The two crystal heads of the splitter at the server room end are plugged into the two ports of the switch, and the two crystal heads of the DP box at the user end are connected to the two users.

It is used for the introduction, fixing, and stripping protection of fiber optic cable, fusion splicing and protection of fiber, storage of pigtail, storage and management of patch fiber, fixed connection and cross connection of fiber, etc. It can also install value-added module units such as optical splitter and wavelength division multiplexer according to customers’ requirements. It is used for the termination, use, and management of fiber optic cables between wiring and equipment.

The optical fiber cable distribution box should be used only when there is no problem with the twisted pair (8 cores are not disconnected).

A pair of fiber optic termination boxes is equivalent to turning a twisted pair into two straight wires. Therefore, the blue, blue-white, brown-white, brown-row method of crystal headers corresponds to the blue, blue-white, brown-white, brown-row process of crystal headers at the other end.

How to connect the Fiber Optic Distribution Box?

Distribution is the location of multiple fiber optics in the distribution box that needs to be divided into several ways to other areas of the fiber optic outlet. In principle, we must use the distribution box as long as the distribution line.

However, now in the home laying, a small number of line branches without distribution box, directly with a three-way split line, only when the number of lines, the use of optical fiber cable DP box split line. It is recommended to use an optical fiber distribution box to divide the line as much as possible.

Network cable using 3, 4, 5 non-twisted pair, with RJ-45 plug to connect the network card and hubs or switches. However, only 4 cores of the 8-core twisted-pair cable (1st, 2nd, 3rd, 6th core) are used, and the remaining 4 substances are not used.

The fiber optic termination box is to use the unused 4 cores, using a single cable instead of two network cables. Specific measures are made DP box; in the distribution box, fiber optic 8 seats of the network cable are into two groups, each group of 4 bodies, respectively, to two RJ-45 media interfaces. At each end of the network, the cable is connected to a splitter box. Realize the purpose of network cable multiplexing, i.e., connecting two terminals with one network cable.

3. Optical splitter module adopts a drawer-type modular design, with solid interchangeability and versatility.

Building (indoor, outdoor) fiber distribution, distribution box using a two-layer structure, the outer layer is mainly composed of optical inserts fixed device, and butterfly introduction of optical cable coiling set device and fiber storage devices; the inner layer is equipped with fiber optic splicing discs and skin cable splicing tray.

What is the role of the Fiber Optic Distribution Box?

1 Fixed and protective function of fiber optic cable

Fiber optic cable into the equipment, there must be a reliable fixed and protective devices, fixed fiber optic cable metal moisture barrier, armored layer and strengthen the core must be reliably connected to the high-voltage protective grounding device, fiber optic cable stripping must be protected with plastic sleeves or spiral tube and fixed into the fiber optic fusion splicing device.

Butterfly cable coiling and tying must be naturally straight, with no twisting, ringing, and other phenomena; it is appropriate to use the necessary fixed devices to ensure no external extrusion and operational damage.

2. Fiber core termination function: distribution box cable termination device must facilitate the fusion of optical fiber and optical fiber or pigtail, installation and maintenance operations, and a surplus of fiber storage space.

3. fiber optic fusion splice joint protection function: fiber optic splice part must be protected. After the fiber and fiber fusion, the common interest must be protected with fusion protection sleeves.

4. cable fiber applicability requirements: must be able to meet the GB, T 7424 in the optical fiber, ITU-T G.652, and ITU-T G.657 fiber or compatible with the fiber, as well as YD, T 1997-2009 butterfly optical cable for access networks.

5. fiber transfer function: the pigtail can quickly and efficiently dispatch the fiber serial number in the cable and change the route of the transmission system. The pigtail length must meet the requirements of the fiber transfer operation.

6. door lock:DP box door lock must be an anti-theft structure with good anti-destructive ability. All distribution boxes should be reserved for the traditional padlock latch or other alternate means of solution.
