Abstract

The invention discloses a long-distance industrial Ethernet transmission switch and a method. The switch comprises a power module, a Cortex-A9 CPU, a SWITCH, a PHY, a logic chip, a control port and abusiness port. The PHY is a BroadR-Reach PHY. The BroadR-Reach PHY establishes data communication with a MAC layer of the switch. An interface format between the BroadR-Reach PHY and the MAC layer isS3MII. The switch provided by the invention is an industrial switch based on a BroadR-Reach drive technology. The switch has the advantages that an additional device relay switch, an optical fiber transceiver and an optical cable do not need to be added; the transmission distance of transmitting 100Mbps Ethernet through a common CAT5 cable is as far as 500 meters; the network transmission time delay is reduced; the cost is reduced; the site wiring is facilitated; and the stable and efficient operation is realized.

Description

technical field [0001] The invention belongs to the field of Ethernet communication, and in particular relates to a switch and a method for long-distance industrial Ethernet transmission. Background technique [0002] In the current Ethernet communication application, whether it is a CAT3 cable with a transmission rate of 10Mbps, the transmission frequency of the cable is 16MHz, and it is mainly used for voice transmission and data transmission with a maximum transmission rate of 10Mbps. It is mainly used for 10BASE-T; CAT5e cable, the transmission frequency of this cable is 100MHz, with small attenuation, less crosstalk, higher signal-to-noise ratio, smaller delay, and greatly improved performance; even the six types of cables with a transmission rate of 1000Mbps, The transmission frequency is 250MHz, which is suitable for Gigabit Ethernet applications. These types of cables have one thing in common, the longest effective transmission distance is 100 meters. In the indust...
