1. What are the commonly used network connection cables, and enumerate their characteristics and uses.
Twisted pair cable
Unshielded twisted pair (5 categories, Super 5, 6 and 7);
Shielded twisted pair (5 categories, Super 5 class, 6 class);
Ultra-five twisted-pair cable (low attenuation, low crosstalk, high SNR, small delay error, high performance)
Category 6 twisted-pair cables (class 6 standard pair balanced twisted-pair cables, connection hardware, jumpers, channels and permanent links have been detailed requirements, providing practical performance of laboratory and field test procedures in the frequency range of 1 to 250 MHz. The 6-category standard also includes requirements for the balance of cables and connection hardware when improving electromagnetic compatibility, providing the basis for the user to choose a higher-performance product, and at the same time, it should also meet the requirements of the network application standards organization.)
Category 7 twisted pair cable (Category 7 is a set of cabling standards that supports transmission of up to 600 MHz of bandwidth on 100 ohm twisted pairs. In September 1997, ISO/IEC began the development of Category 7 cabling standards. From Category 7 standards At the beginning, there has been a history of "RJ" and "Non-RJ" interfaces in the history of wiring. There are no final conclusions about the seven types of standards. At present, there are active discussions on seven types of draft standards in the world.)
Large-pair twisted-pair cable (Large-log cable is composed of 25 pairs of copper conductors with an insulating protective layer, transmission speed is 100MHz.)
The
2. Fiber optic cable
According to the occasion (indoor cable, outdoor cable, indoor and outdoor universal cable)
According to laying method (overhead cable, direct buried cable, pipe cable, underwater optical cable)
According to the structure (tight sleeve fiber optic cable, loose sleeve fiber optic cable, single fiber optic cable)
Indoor fiber optic cable may be used for voice, data, video, telemetry, and sensing at the same time. Since the indoor environment is much better than outdoors, it is generally not necessary to consider natural mechanical stress and rainwater and other factors, so most indoor optical cables are tight-fitting, dry, flame-retardant, and flexible optical cables.
Outdoor optical cables have higher tensile strength, thicker protective layers, and are generally armored (ie, metal sheaths).
