Comparison The Pros And Cons Of Cat7 Cable & Optical Fiber Cable
May 03, 2018

As we all know, in the network wiring of network signal transmission will use transmission media, in the wiring, people often use both cable and fiber transmission media. The types of cables are mainly classified into a shielded twisted pair and unshielded twisted pair. Optical fibers are also classified into multimode fibers and single-mode fibers. Today, here we share with you the advantages and disadvantages of the Cat7 network cables and optical cables.

 

1, Aluminium foil shielded twisted pair FTP, bandwidth, anti-interference performance, with low smoke and halogen-free features. In contrast, the shielded cable is higher than the non-shielded cable in price and installation cost, and the cable bending performance is slightly inferior. Category 6 and previous shielding systems used this form.

 

2. Unshielded twisted pair UTP is the most widely used cabling system in China. It is suitable for network applications with transmission bandwidth below 250MHz and no special performance requirements. Its advantages are good overall performance, low price, and convenient construction and maintenance. Category 6 cabling systems have reached the performance limit of the unshielded twisted pair.

 

3, Independent shielded twisted pair STP, each pair of lines has an aluminium foil shielding layer, four pairs of lines together there is a common metal braided shielding layer, which is the standard structure of the seven types of network cable. It is suitable for high-speed network applications, provides highly secure transmission, supports future new applications, and helps to unify the current network application wiring platform, allowing various information from e-mail to multimedia video to be on the same high-speed system. Transmission.

 

The extra shielding makes the Cat7 wires a larger wire diameter. These characteristics require special care in designing the routing and termination space, leaving a lot of space and a large bend radius. Moreover, due to its excellent shielding design and high bandwidth, a typical Class 7 channel can even provide a pair of 862 MHz bandwidth at a time for transmitting cable TV signals, an analogue audio signal on another pair, and then at the third. Four-wire transmission of high-speed local area network information. This kind of application is currently unthinkable, but will soon be implemented by seven types of cabling systems.

 

Compared to fiber-optic LANs, the solutions of the Cat7 wire-line systems provide the desired performance and bandwidth, but their overall cost is only a fraction of that of fiber. Some people think that the fiber optic system can bring enough bandwidth to people, and the price of fiber optic cable and seven types of cable is close. However, if the cost factors of optical fiber routers, optical switches, and optical network cards are taken into consideration, the price advantage of optical fibers will be quickly lost.

 

4. Fiber optic cable, especially single-mode fiber optic cable, can be used for high-speed network transmission and has the advantages of inherent immunity to electromagnetic interference, strong reliability, and support for long-distance transmission. It is the ideal network transmission medium in the future, and its status is increasingly important. However, the cable equipment, materials, and termination costs are relatively expensive and the installation is relatively complicated, so it is generally suitable for long-distance and large-capacity wiring. At present, 62.5/125 μm multi-mode optical fiber cable has become the mainstream wiring medium in the integrated wiring backbone system, and the application in the horizontal system has become increasingly widespread.

 

To sum up, for the choice of network cabling system, different choices are needed because of different needs. It is a rational choice that suits oneself.
