What does weak power "composite wiring" contain?

The integrated wiring system is like the nerve in the building. It uses a series of high-quality standard materials to synthesize the voice, data, image and part of the control signal system with a unified transmission medium in a modular combination. The planning and design, integrated in a standard wiring system, organically connects the three subsystems of modern architecture, providing a physical medium for system integration of modern buildings. It can be said that the success of a structured cabling system is directly related to the success or failure of a modern building. It is crucial to choose a high-quality integrated wiring system.
· router
Also known as a gateway device, it is used to connect multiple logically separated networks. The so-called logical network represents a single network or a subnet. When data is transferred from one subnet to another, it can be done through the routing function of the router. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish a flexible connection in a multi-network interconnection environment, and can connect various subnets by completely different data packets and media access methods, and the router only accepts the source station or The information of other routers is an interconnected device at the network layer.

· Switch
A network device for electrical signal forwarding. It provides an exclusive electrical signal path for any two network nodes that access the switch. The most common switch is an Ethernet switch. Other common ones are voice switches, fiber switches, and so on.
· Fiber Transceiver
An Ethernet transmission medium conversion unit that interchanges a short-distance twisted pair electrical signal with a long-distance optical signal is also referred to as a photoelectric converter in many places. The product is generally used in an actual network environment where the Ethernet cable cannot be covered and must use fiber to extend the transmission distance, and is usually located in the access layer application of the broadband metropolitan area network; at the same time, it helps to connect the last mile line of the optical fiber to the metropolitan area. The network and the outer layer of the network also played a huge role.
· Fiber
The abbreviation of optical fiber is a fiber made of glass or plastic, which can be used as a light-conducting tool. The transmission principle is 'total reflection of light'. Former Hong Kong Chinese University President Gao Wei and George A. Hockham first proposed the idea that fiber can be used for communication transmission, so Gao Hao won the 2009 Nobel Prize in Physics.
· Optical cable
Manufactured to meet optical, mechanical, or environmental performance specifications, it is a communication cable assembly that utilizes one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber (glass wire as thin as hair), plastic protective sleeve and plastic outer skin. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. The optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain manner, and a sheath is sheathed, and some outer cladding layers are also covered to realize optical signal transmission. That is, a cable formed by an optical fiber (optical transmission carrier) through a certain process. The basic structure of the optical cable is generally composed of a cable core, a reinforcing wire, a filler and a sheath, and a waterproof layer, a buffer layer, an insulated metal wire and the like as needed.
· Patch panel
The purpose is mainly a modular device for managing front-end information points at the central office. The front-end information point cable (Super Category 5 or Category 6 cable) enters the equipment room and then enters the distribution frame first. The line is placed on the module of the distribution frame, and then the patch panel and switch are connected by jumpers (RJ45 interface). . In general, the patch panel is a device for management. For example, if there is no patch panel, the information point of the front end is directly connected to the switch, and if there is a problem in the cable, it is faced with rewiring.
That is, the uninterruptible power supply is a system device that connects a battery (mostly a lead-acid maintenance-free battery) to a host computer, and converts the direct current into a commercial power through a module circuit such as a host inverter. It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc. When the mains input is normal, the UPS supplies the mains voltage to the load for use. At this time, the UPS is an AC mains voltage regulator, and it also charges the internal battery; when the mains is interrupted (accident blackout) At the same time, the UPS immediately supplies the battery DC power to the load through the inverter zero-switching conversion method to continue to supply 220V AC power, so that the load maintains normal operation and protects the load soft and hardware from damage. UPS devices typically provide protection against excessive voltage or low voltage.
· Server
A computer that manages resources and provides services to users, usually divided into file servers, database servers, and application servers. A computer or computer system running the above software is also referred to as a server. Compared with ordinary PCs, servers require higher stability, security, performance, etc., so CPU, chipset, memory, disk system, network and other hardware are different from ordinary PCs.
· Network panel
It refers to a type of cabling product that is applied to the work area wiring subsystem and is suitable for multi-type module installation. Its main function is to fix the module and protect the cable at the exit of the information to play a role similar to the screen. The network panel is not the main product component that affects the performance of the wiring system, but in the entire wiring system, it is one of only a few products exposed on the surface of the wall. Its performance and appearance directly affect the overall wiring. Effect.
