User area subsystem design: The user wiring subsystem consists of wires connecting the terminal equipment to the information socket. The number of voice and data information sockets is determined according to user requirements. (Structured wiring consists of: work area subsystem, horizontal subsystem, management subsystem, equipment room subsystem, backbone subsystem and building cluster subsystem.
The installation position of the user information socket is determined: the RJ45 embedded information socket and the power socket next to it should be kept at a distance of 30cm to 150cm, and the low edge of the information socket and the power socket is 30cm away from the floor level (maintain the same height as the power socket).
Horizontal zone design
The horizontal wiring subsystem extends the trunk subsystem lines to the user's work area. The system is an information socket that connects to each work area from each sub-wiring room.
The horizontal part of the data system line uses LUCENT, AMP super five twisted pairs. The system has good flexibility and has good support for future digital phones, video phones, and multimedia high-speed phone applications. LUCENT and AMP are Cat5e lines conforming to EIA / TIA568 standards.
When transmitting data, it can transmit at a standard speed of 10Mbps within a range of 150 meters and guarantee a transmission rate of 155Mbps within a range of 100 meters. In addition, it can also transmit various 70V DC voltages and weak current signals within the frequency of 10MHZ and 100MHZ at the corresponding distance.
Design of main wiring closet
The main wiring room is composed of cables, connectors and related supporting hardware in the equipment room, which interconnects various devices of public system equipment. This subsystem connects the cross-connections of trunk lines and the intersections of wiring with public system equipment.
The main distribution room of the data system is close to the staircase. The cabinet is a 19-inch 35-unit B-type, 1.8 meters * 0.6 meters * 0.6 meters, with double front and rear doors to manage the distribution frame and network products. Use five types of twisted pairs for data jumpers.
There should be at least two single-phase three-level power sockets with 220V voltage and 10A current that are dedicated to the system and meet the requirements of general office lighting in the wiring room of the data system. This line should not be connected in parallel with other large equipment, and it is best to connect to the UPS first to ensure the power supply to the network equipment.
General Purpose Rectifier Bridge
A bridge rectifier provides full-wave rectification from a two-wire AC input, resulting in lower cost and weight as compared to a rectifier with a 3-wire input from a transformer with a center-tapped secondary winding.
