ThinNet Fiber

These types of cable can transmit signals over a distance about 100 m. As a rule, used in local area networks is UTP. STP has a braided sheath of copper thread, which has a higher level of security and quality than the cable sheath UTP. The cable STP each pair is additionally screened (it is wrapped a layer of foil), which protects data transferred from external interference. This solution allows to maintain high speeds over longer distances than in the case of Cable UTP, Twisted pair is connected to a computer using an RJ-45 (Registered Jack 45), which resembles a telephone jack RJ-11 (Regi-steredjack).

Twisted pair is capable of providing the network at speeds of 10.100 and 1000 Mbit / sec. Coaxial cable consists of copper wire covered with insulation, metal braid shield and outer shell. The central wire cable signals are transmitted, in which preliminary data were transformed. Such a wire can be as solid and stranded. To organize the local network uses two types of coaxial cable: ThinNet (thin, 10Base2) and ThickNet (thick, 10Base5).

Currently, local area networks based on coaxial cable, almost never occur. In based on fiber optic cables are fiber optics (optical fibers) for which data are transmitted as pulses of light. Electrical signals over fiber optic cable is not broadcast, so the signal can not be intercepted, which virtually eliminates unauthorized access to data. Fiber-optic cable used for transporting large volumes of information on the maximum available speed. The main drawback of such a cable is its fragility: it is easily damaged, and mount and connect only with the help of special equipment.
