Abstract
The utility model discloses a fiber transceiver supporting poe and remote power supplying, which comprises a fiber transceiver and a PSE controller chip. The PSE controller chip is arranged on the rj45 interface side of the fiber transceiver and connected with idle line pairs marked by 4, 5, 7, 8 inside an rj45 interface. The pins marked by 4, 5 of the rj45 interface are connected with an anode while the pins marked by 7, 8 of the rj45 interface are connected with a cathode. The PSE controller chip is meanwhile connected with a 48-volt power supply module and the ground. The fiber transceiver supporting poe and remote power supplying is formed by additionally arranging a poe+ controller chip (Broadcom BCM59103) on a conventional fiber transceiver. The fiber transceiver supporting poe and remote power supplying overcomes the power acquisition difficulties of power receiving devices and solves the problem that a common 802.3af cannot satisfy the power supply demands of high-power equipment. The construction and maintenance cost is further lowered.
