Description
Technical field
The present invention relates to a kind of network cable, particularly relate to the network cable that a kind of electromagnetism interference is effective.
Background technology
NetworkCable network connection is connected to, from a network equipment (such as computer), the medium that the another one network equipment transmits information, is the basic component of network. In the local area network that we commonly use, it may also be useful to netting twine be also that there is broad variety. Under normal conditions, a typical local area network generally can not use multiple different types of netting twine to carry out interconnection network equipment. Large-scale network or Wide area network will use different types of netting twine in order to dissimilar network is linked together. In the netting twine of numerous kinds, any netting twine of concrete use will according to the topological framework of network, and network structure standard and transmission speed are selected.
UTP can calculate a kind of netting twine using frequency the highest in current local area network. This kind of netting twine wraps up eight signal wires inside plastic insulation crust, they every two be one to mutual winding, it is altogether four right to be formed, and twisted-pair feeder also hence obtains one's name. The object of the mutual like this winding of twisted-pair feeder is exactly utilize the electromagnetic field that in copper cash, electric current produces to act on the interference offsetting adjacent lines mutually and reduce the interference from the external world. The number of times that the often pair of line is mutually wound around in per inch length determines anti-interference ability and the quality of communication, be wound around its communication quality more tight is more high, so that it may to support higher network data transfer rate, its cost is also more high certainly. International Electrotechnical Commission and international telecommunication council EIA/TIAElectronicIndustryAssociation/TelecommunicationIn dustryAssociation have established the international standard of UTP netting twine and have been divided into 5 classifications (Categories or abbreviation CAT) according to the field used, and the netting twine manufacturer of every kind all can mark its kind on it insulate crust.
STP uses metal screen layer to reduce extraneous electromagnetic interference (EMI), after screen layer is by correctly ground connection, the electromagnetic interference signal received can be become electric current signal, reverse with the undesired signal electric current formed at twisted-pair feeder. As long as two electric currents are symmetrical, they just can be offset, and does not bring noise to receiving end. , when screen layer is discontinuous or screen layer electric current is asymmetric, will reduce and lose shield effectiveness even completely and cause noise. And the effect shielded depends primarily on shielding material.
