Optical fiber, short for optical fiber, is made of glass or plastic, has light guiding ability, optical fiber network, and uses fiber optic total reflection to the home or computer room, also called LAN. It is now a further direction for the development of human networks. It is considered to be the best broadband connection method, and the rapid development of wireless networks today. Optical fiber networks provide people with very convenient access conditions for metropolitan area networks and access networks. Insufficient capacity provides a mitigating effect. It is the fastest development in the field of human electronic networks today.
Eerste, the introduction of fiber performance
The frequency of the fiber-optic network carrier is high, the frequency band, the wide-band signal that can be transmitted is strong, and because of its light weight, small diameter, small proportion of glass fiber, and because of its strong anti-interference ability, it only transmits light, is not conductive, and is not subject to magnetic field. The impact is very stable. The reliability and cost of performance are also low. The foreign fiber network has long been developed. In recent years, some first-tier cities in China are also developing. It is a network that many communities pursue. Now, we will let every household enjoy fiber treatment this morning. Maar, how to connect the fiber optic junction box?
Tweede, how to wire the fiber junction box
1. Eerste, we should choose the right and correct junction box. We mainly look at the current of the components in the junction box. One is to see the maximum current of the working, and the maximum current output when the output is shorted. Generally, we calculate according to the short-circuit current. The rated current, so that it can be used more safely, so before assembly, know where the production components are and calculate the correct safe current to ensure our future use.
2. The fiber optic junction box is provided with a base, and the fiber holder is also fixed on the base. The cover is opened. The junction box installed on the ground should be carefully installed to ensure the stability of the base. The junction cover can be opened, but it must be waterproof and dustproof. For other functions, the junction box should be flush with the ground to prevent the junction box from being wrong. There are also wiring ports at both ends of the base. We should connect the optical fiber to the wiring port, and then cover and cover the cover for testing.
3. When wiring, you should pay attention to safety, ensure the current, and ensure that the rated current of the junction box is sufficient. The junction box installed on the wall should be about 30cm away from the ground, so be sure not to touch the junction box when the ground is active. The various socket panels in the junction box should have marking instructions, and the tool area should ensure that there is sufficient space in the junction box to meet the design requirements. Safety should be observed when connecting the operating holes in the junction box.
4. Optical fiber networks are now widely distributed in many areas, and they provide very convenient conditions for people to access the Internet. Maar, we must also pay attention to the safety of fiber optic network installation, correct wiring, and let the technicians operate to ensure our safety and use. The life of the junction box.
