What equipment do you usually need when wiring a smart home?

Some of the equipment required for smart home wiring are as follows:

1. Twisted-pair. Twisted pair is the most common transmission medium now. It consists of two mutually insulated copper wires, typically 1 mm in diameter. The two wires are twisted together to prevent their electromagnetic induction from generating interference signals in adjacent pairs. Current double

The twisted pair cable generally includes four twisted pairs, specifically white orange/orange, white blue/blue, white green/green, and white brown/brown. Common twisted pairs are boxed and shafted and are 305 meters (1000 feet) long. At present, the most widely sold in the domestic market is the super five twisted pair of 305 meters cable length carton packaging.

2, rj45 module (modular). Commonly there are four basic module sockets, the 8-core module socket is usually called "rj45", and the 6-core module socket is usually called "rj11". Sometimes these "rj" devices are easily confused with something called usoc (universal service ordering codes). "rj" means "registered jack", and each basic socket can be connected to a different configuration of rj. For example, a 6-pin socket can be connected to rj11 (1 pair), rj14 (2 pairs) or rj25c (3 pairs); an 8-pin socket can be connected to rj61c (4 pairs) and rj48c. 8-core (keyed) can be connected to rj45s, rj46s and rj47s. The fourth modular jack is a modified modular jack (mmj), which is a voice device designed by dec to connect to dec. The modules in the integrated wiring are used to terminate the cable and effectively connect to the jumper. Modules are used in the distribution frame or in the home wiring box at the exit of the information panel.

3, patch panel (pantch pannel). The patch panels are versatile and cost-effective for horizontal and vertical cabling, or for direct connection to hubs and horizontal cabling systems. Available in 12, 24 and 48 ports. The terminal is 110idc with labels on the front and back for easy identification. The product is designed for several 19-inch installations. The standard 19-inch rack-type patch panels are usually commercial wiring, and the home wiring uses six small units, saving space, easy installation, and low cost. It can be installed in a small home wiring box.

4, crystal head. This accessory product is not included in the standard integrated wiring design and installation. It will only be used as a component in the finished jumper. When the home wiring is used, the original jumper may not meet the length requirements. The user may Purchase crystal heads and cables with special crimping tools.

5, the panel. This is a widely used accessory that is also widely used in the field of household power and household appliances. When wiring, the panel is installed with a fixed module at the information exit position, and the domestic standard 86 standard back box is often used. There are two types of single and double. The common wiring panel mainly installs information export of computers and telephones, and the multimedia information panel even has computers, telephones, catvs, and audio interfaces.

6, jumper (connection line). Also known as the network cable. The copper jumper in the wiring is actually a short twisted pair. The two ends are crimped to the crystal head to complete the connection between the module, the patch panel and the active equipment. The common length of the jumper is 1 meter and 2 meters. 3 meters, 5 meters, 10 meters. It is recommended to use the original factory jumper in the home wiring room, because the original jumper technology is rigorous and can withstand repeated insertion and removal times.

7, fiber. Fiber is a fine, flexible medium that transmits light, centered on a light-propagating glass core. The optical cable is composed of a bundle of optical fibers, referred to as optical cables. Optical cable is the most effective transmission medium in data transmission. It has the advantages of wide frequency band, good electromagnetic insulation performance and low attenuation. Commonly used optical cables are: 8.3μm core, 125μm outer layer, single mode fiber cable, 62.5μm core, 125μm outer layer, multimode fiber cable, 50μm core, 125μm outer layer, multimode fiber cable, 100μm core, 140μm outer layer, multimode fiber cable .

8. Fiber to the home (ftth, fiber to the home) is a term that has recently been mentioned more. It refers to the connection of fiber optic networks to communication access networks in general households. From the perspective of technology development, fiber to the home (ftth) is the ultimate solution for the access network. The advantage of fiber-to-the-home is that the bandwidth is not limited for the user, which provides bandwidth guarantee for the broadband service to enter the home; in addition, the fiber directly arrives at home, free from external interference and no leakage problem, and the outdoor device can do Passive, avoid lightning strikes, more reliable performance, and lowest power supply costs; but the disadvantage is that the cost is too high to be widely promoted.

9, coaxial cable. The coaxial cable is made of hard copper wire and is covered with a layer of insulating material. This layer of insulating material is surrounded by a densely woven mesh conductor, which is covered with a protective material. There are two widely used coaxial cables. Baseband coaxial cable and broadband coaxial cable. Broadband coaxial cable is used in the cable TV network of the city or the community to access the home and the home content television system. At present, more talk about cable TV broadband access is also based on broadband coaxial cable transmission.

10. Audio video cable. There are many audio and video lines involved in home entertainment systems: audio lines include FM AM antennas, analog signal lines, fiber-optic coaxial digital lines, video lines include composite video and s-terminal lines, and coaxial cables for cable TV are common RF lines. There are also professional speaker cables. The price of various wirings varies greatly, especially for audio cables. The price of speaker cables for audiophiles is also very different. People in this circle are also using equipment and wires that are surprising to ordinary people. In general, home users do not need to replace the original audio cable, because most audio components are wired with other components and generally work well. These connections are usually connected to nearby devices, not far from each other, but the audio cable may be longer, because in addition to the home theater system in the living room, the speakers and speakers in other rooms need to be connected to the av amplifier when the distance is far away. Use the home wiring system to arrange, use the high-quality speaker cable in the home wiring to connect the av amplifier to the home wiring box, and then distribute it to other rooms by the home wiring box. For example, a #8525c speaker cable is certified by the thx home theater system. The cable is used to connect the front speakers up to 30 feet and is used to connect the surround speakers up to 60 feet. Wiring should be handled properly. Do not tie the power cable to the speaker cable when wiring. The AC will affect the signal. Wiring can not be knotted, otherwise it will affect the tone. Wiring should be shortened too long, and many wirings are directional, so don't make mistakes.

11, home wiring box. The home wiring box is the management equipment center of the home wiring, usually connecting and managing the module configuration box, communication module, video module, network module, audio module, system socket, cable, home intelligent management system, etc., if the home av center equipment More are also equipped with dedicated cabinets, which can be placed together with home wiring equipment in a standard cabinet, such as a 39u standard cabinet.
