The transmission medium of the digital network is mainly high-capacity digital communication cable and optical fiber cable of twisted pair group.
The twisted pair digital communication cable is a network transmission medium which is commonly used at present, has the characteristic of low price, and is the digital communication cable with highest cost performance at present. It is formed by twisting eight insulating core wires into four pairs of wire groups, and then the four pairs of wires are combined into a cable, and finally the outer sheath is extruded to prepare the finished cable. However, in the existing cable structure, the relative positions between the cable groups are fixed only by the cable outer sheath, and the cable structure is pulled, pulled and twisted by the cable, so that the relative positions of the cable groups are displaced and changed, even in the cable looping process, the structural parameters of the cable structure are changed, the cable structure is unstable, the degradation of performance indexes such as input impedance, near-end crosstalk, far-end crosstalk and attenuation is necessarily caused, and the improvement of the working frequency and the data transmission speed of the data communication cable is severely restricted. In order to improve the transmission performance of the data cable, the data cable using technologies such as a cross-shaped separation skeleton and various shielding structures has been developed, so that the transmission rate of the data cable is continuously improved, and the corresponding digital communication cable needs to be developed from category 5, category seven to category eight and communication cable products with ultra-high transmission frequency.
Optical fiber communication is a novel transmission means of modern communication network, the generation and development of optical fiber communication is an important revolution in the history of communication, and due to the rapid development of internet service and the growth of audio, video, data and multimedia applications, the demands for high-capacity (ultra-high speed and ultra-long distance) optical wave transmission systems and networks are more urgent. Compared with the traditional electric communication, the optical fiber communication has the main advantages of wide transmission frequency band, large communication capacity, low transmission loss, long relay distance, metal material saving, reasonable use of resources, strong insulation and electromagnetic interference resistance, strong corrosion resistance, strong radiation resistance and the like. However, the optical fiber is expensive, and the optical fiber cannot withstand tensile force, and particularly, when the optical fiber is laterally pressed, the central axis of the fiber core is slightly bent to cause an increase in light loss, resulting in a decrease in transmission distance and transmission quality.
The current photoelectric composite cable is actually a combination of an optical fiber and a power transmission copper wire, and can only be used as a single transmission connector, namely, is only used for transmitting optical signals and electric energy. The optical fiber is used for transmitting digital signals, the cable can only transmit electric energy and cannot transmit digital signals, the optical cable composite cable equipment has insufficient applicability and field adaptability, can not meet various choices and different requirements of users, has limited application range, can only be suitable for occasions of transmitting digital signals by the optical fiber, and can not be suitable for equipment matched with the digital signal cable.
