As we all know, in the network cabling network transmission through the network will use the transmission medium, in the wiring people often use cable and optical cable these two transmission media. Cable type is divided into shielded twisted pair and unshielded twisted pair of these two, optical cable is also divided into multi-mode optical cable and single-mode optical cable. Today, here and share with you under the seven types of cable and optical cable the pros and cons of contrast.

1. Aluminum foil shielded twisted pair FTP, large bandwidth, anti-jamming performance, with low smoke and halogen characteristics. In contrast, the shielded wire is lower than the non-shielded wire price and installation cost, and the cable bending performance is slightly worse. Six types of lines and the previous shielding system to adopt this form.

2. Unshielded twisted pair UTP, is the current application to teach more cabling system for transmission bandwidth below 250MHz, no special performance requirements of the network applications, the advantage is the overall performance is good, cheap, more convenient construction and maintenance The Six types of cabling system has reached the performance limit of unshielded twisted pair.

3. Independent shielded twisted pair STP, each pair of wires have an aluminum foil shield, four pairs of lines together there is a common metal braided shield, which is the standard structure of seven types of cable. It is suitable for high-speed network applications, providing a high degree of confidential transmission, support the future of new applications, help to unify the current network application wiring platform, making e-mail to multimedia video information, can be in the same set of high-speed system In the transmission.

The additional shields make the seven lines have a larger wire diameter, which requires special care when designing the installation route and termination space, leaving a lot of space and a large bend radius

And because of its excellent shielding design and high bandwidth, a typical seven-class channel can even provide a pair of lines at the same time 862MHz bandwidth for the transmission of cable television signals in another line to transmit analog audio signals, and then in the third , Four-wire transmission of high-speed LAN information. This application is now unimaginable, but will soon be achieved by seven cabling systems.

Compared with the optical cable LAN, the seven network cable system solutions provide the desired performance and bandwidth, but the overall cost is only a fraction of the optical cable. Some people will think that the optical cable system can give people enough bandwidth, and the optical cable and seven cable prices close. However, if taking into account the optical cable router, optical switches and optical card cost factors, optical cable price advantage will soon be lost.

4.optical cable, especially single-mode optical cable can be used for high-speed network transmission, and innate electromagnetic interference immunity, reliability, support for long-distance transmission, etc., is the ideal future network transmission media, its status is increasingly important. But optical cable equipment, materials and termination costs are more expensive, the installation is also relatively complex, it is generally suitable for long-distance and high-capacity wiring. At present, 62.5 / 125μm multifunctional optical cable has become the mainstream wiring medium in the integrated wiring system, and the application in the horizontal system has become more and more extensive.

To sum up, for the choice of network cabling system, the need for different needs and have different options for their own is a rational choice.

The above is the cable and the optical cable on the merits of the relevant introduction, learn more about the contents of the optical cable, please pay attention to kingsignal official website.
