Network cable switch of extra long distance transmission

Abstract

The invention discloses a network cable switch of extra long distance transmission. The network cable switch comprises a PCB motherboard, a singlechip, a switching chip and a power chip are arranged on the PCB motherboard, the singlechip is connected with the switching chip, the singlechip is connected with a dial switch, the switching chip is connected with a 100M optical module through an SFP socket, the100M optical module is connected with an optical network port, the switching chip is connected with four network transformers, each network transformer is connected with a RJ45 network cable socket, and the RJ45 network cable socket is connected with a power grid port; and the switching chip establishes a mapping relation between a source MAC address in a data frame with a switch port according to an Ethernet communication protocol rule to forward a data signal and realize a data exchange function under the configuration and management of the singlechip. Compared with the prior art, the network cable switch has the following advantages: the transmission distance of the network cable switch provided by the invention in ordinary 5 UTP cables can reach 250 meters, which is 2.5 times as large as that of the same type of products; and meanwhile, the network cable switch is an innovative product which is low in overall BOM cost, excellent in performance and low in cost.

Description

technical field [0001] The invention relates to a switch, in particular to a network cable switch for ultra-long distance transmission. Background technique [0002] The existing ordinary network cable switch is only designed for the common application of the switch chip under the standard bandwidth, without any special improvement on the drive capability of the chip's grid port, so the transmission distance of the network cable is only maintained at the industry standard of 100 meters. The upper limit, so there is a shortcoming that it cannot do long-distance transmission greater than 100 meters, and cannot meet the long-distance network cable transmission requirements greater than 100 meters. Contents of the invention [0003] The present invention aims to solve the above-mentioned shortcomings, and provides a network cable switch for ultra-long-distance transmission. [0004] The above object of the present invention is achieved through the following technical solution...
