The optical fiber distribution box

Optical splitter box – splitter box can put two 1 to 8 secondary. 1. The optical fiber distribution box at the user end gives 2 cores, the maximum optical split ratio is generally 1:64, and a secondary split of 1 to 8 is; while the 48-core optical fiber distribution box has 48 ports at the end, and the main optical cable is also It will occupy one end. The main optical fiber cable is 12 cores, so there are only 36 ports left on the optical fiber distribution box. If the user is fully equipped, they can put up to two. 2. It is an interface device used to connect the main optical cable and the distribution optical cable outdoors, in the corridor or indoors. 3. The optical splitter is used to broadcast the light beam in one fiber core to multiple fiber cores through physical channels. The purpose is to improve the utilization efficiency of the trunk fiber and reduce the logarithm of the trunk fiber. 4. The general optical splitter has 1 point 2, 1 point 4, 1 point 8, 1 point 16, 1 point 32, 1 point 64, 1 point 128. If the user is concentrated on one optical path, only one optical splitter can be installed. It is called 1 split. If the distribution of users is relatively scattered, two splitters can be installed on one optical path, such as 1:2, and then 1:32, so the actual maximum splitting ratio is still 1:64, but it can be used in two On the lines between the optical splitters, the number of cores of the optical cable is reduced or the utilization rate of the cores is improved. 5. The optical splitter does not necessarily need to be placed in the optical delivery box, it can be placed according to the actual situation. However, the optical splitter is currently mainly used for splitting light from the backbone fiber, so most of the optical splitters are placed in the optical box, and the optical box has good mechanical properties and can play a better protective role.

It also provides mechanical protection and environmental protection for the fiber and its components, and allows for proper inspection to maintain the highest standard fiber management. A fiber distribution box is similar to a fiber distribution box, which is equivalent to a fiber optic cable connector, such as a 12-core fiber distribution box. From the optical splitter, the 12-core fiber optic cable is placed to the fiber distribution box, and then divided into 12 leather cables to the user end. For fiber optic cables, etc., we must choose high-quality products that meet the standards, so as to ensure our network transmission, we use Finite. a) Corridor (indoor, outdoor) optical fiber distribution box should be complete, all plastic parts have no thorns, no bubbles, no cracks, no holes, no warping, no impurities and other defects, and the thermal deformation temperature is ≥85 °C, which meets the requirements of the line 15-year service life requirement. b) Corridor (indoor, outdoor) fiber optic fiber distribution box, the internal metal plate of the box is made of Q235 cold-rolled plate, with a thickness of not less than 2mm, and the surface is galvanized.

It becomes an optical splitter chassis, but this is not a random addition, and the loss of the entire link must be considered. The naming specifications are collectively referred to as YDT’s standards. The basics are like this: Assuming that an optical box with a full capacity of 576 cores is point A, you can end multiple optical cables (optical cables that do not exceed the total capacity), and then you have a 48-core optical cable that leads from point A to point B The splice box is divided into 8 branch optical cables from the splice box at point B, each cable is spliced with 6 cores, and then the 8 6-core branch optical cables are respectively connected to different fiber distribution boxes to form ends, and then from the fiber distribution box. It is welded to the broadband panel where the leather cable enters the home, and then connect one end of the pigtail to the broadband panel and the other end to the cat. In short, a pigtail (two ends) is generally used in the optical box to connect the two directions of fiber cores you use through the pigtail, which is called the active connection method. is a fixed connection. The optical cable must first be terminated, and then connected with pigtails, such as a pair of fibers connected to an optical splitter.

At the same time, value-added module units such as optical splitters and wavelength division multiplexers can be installed according to customer requirements. The optical fiber distribution box is the optical fiber distribution box, which is suitable for the wiring connection between the optical cable and the optical communication equipment. Through the adapter in the distribution box, the optical signal is drawn out with the optical jumper to realize the optical wiring function. It is suitable for the protective connection of optical cables and distribution pigtails, and is also suitable for the use of optical fiber termination points in optical fiber access networks. Generally, the stranded optical cable can achieve 144 cores, that is, there are 12 bundles in the middle, and each bundle has 12 cores. Of course, there are also manufacturers that can make the central bundled optical cable up to 24 cores. The optical fiber can do 288 cores. Stranded optical fibers also have 8 bundles, which are mainly determined by the number of cores. Optical fiber splitter box: also called splitter box, light splitter box, splitter box… People in different places have a variety of different names, the materials are: ABS, PC alloy, SMC, plastic, cold-rolled Boards, etc., are mainly used for wiring optical cables through the optical splitter and the user’s butterfly-shaped introduction optical cable interface.

The distribution of the core refractive index is the same, stepped. Since the SI type light wave is reflected in the optical fiber and progresses, the time difference of each optical path is generated, the output light wave is distorted, and the color excitation is large. As a result, the transmission bandwidth is narrowed, and SI-type MMF is rarely used at present. When the working wavelength of single-mode fiber is , the mode field diameter is about 9Pm, and its transmission loss is about /km. At this time, the zero-dispersion wavelength is exactly at . In the quartz fiber, the transmission loss of the segment is the smallest (about /km) in terms of raw materials. The erbium-doped fiber amplifier (EDFA) that has been practical now works in the wavelength band and can achieve zero dispersion, which is more conducive to long-distance transmission in the application band. Therefore, by cleverly using the synthetic cancellation properties of the dispersion of the silica material in the fiber material and the dispersion of the core structure, the zero dispersion in the original segment can be made, and the shift to the segment also constitutes zero dispersion.
