, 100 pairs, 300 pairs, 900 pairs of wall mounted types, and from the main distribution frame between the main equipment to the distribution frame between each distribution line, no matter the connection trunk or horizontal cable, all use this distribution frame. the advantage of the 110 fish bone distribution frame is its small size, high density, and low price. It is mainly used together with the 25/50/100 pairs of large logarithm cables. Its disadvantage is that it is troublesome to connect t

A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshielded twisted pair wires (UTP-unshielded t

packets are no longer differentiated on the DSLAM device after they are uplink through the IAD, and are directly passthrough to the broadband network bearer network. voice and data are connected to the voice and data services through their respective IP address headers. This solution is suitable for applications of families or small companies that only support twisted pair wires; IAD is connected directly to the downstream RJ45 port of the RTU, and t

the electromagnetic principle: it can be considered that the interference signals of the two signal lines are of the same phase and equal amplitude. After the two lines are combined, they both resist external interference and prevent themselves from interfering with others. Twisted Pair wires are commonly used.Most local networks use Unshielded Twisted Pair wires (UTP-Unshielded Twisted Pair) as the transmission medium for cabling. The network cable consists of a long Twisted Pair wires and

repeater to expand the topological distance of the network. This is because signal attenuation occurs after long-distance transmission. The function of a repeater is to sort out the signals that have been degraded and become incomplete, re-generate a complete signal and continue transmission. A repeater is the predecessor of a general hub. A hub is a multi-port repeater. Take the hub in Figure 1 as an example. A hub generally has a BNC connector, an AUI connector, and an

RJ11 the definition and standards of the relevant provisions. 　　 RJ11 usually refers to the 6-position (6-pin) modular jack or plug. The connectors do not have international standards and are mentioned in the generic cabling standard. Also, this name is often used in the 4-pin version of the modular connector, causing confusion. 　　 In the generic cabling standard, there is no separate mention of ' RJ11 ', all the connecting devices must be 8 stitches. Therefore, RJ11 and

A lan connects a single computer or terminal using communication lines and follows certain protocols for information exchange to achieve resource sharing. Among them, communication lines, that is, commonly used transmission media include: twisted pair wires, coaxial cables, optical fiber cables, etc. Most local networks use unshielded twisted pair wires (UTP-unshielded twisted pair) as the transmission medium for cabling. The network cable consists of a long-distance twisted pair wires and
