Description: 1 electrical port and 1 single-fiber SC optical port to achieve photoelectric signal conversion between twisted pair and optical fiber. Only a single core fiber can complete the signal transmission of one way, and double the fiber to increase the data transmission capacity of the fiber by a factor of two. Complies with IEEE802.3 10Base-T and IEEE802.3u 100Base-TX, 100Base-FX standard. Has 10M/100M self-adaptive ability. The electrical port can adapt the direct line/cross line connection mode. Specification: Supports full-duplex/half-duplex mode of operation. Support IEEE802.3X full-duplex flow control and half-duplex back pressure flow control. Support to prevent broadcast storm function; Support for 1916 Byte jumbo frames (optional). Built-in lightning protection circuit can greatly reduce the damage caused by lightning induction. Twisted pair cables are up to 100 meters long; single mode fibers are up to 100 kilometers long. There are 6 LED indicators: Power, TX 100, TX Link/Act, FX 100, FX Link/Act, FDX/Col; it is easy to monitor the working status of the transceiver and determine the cause of the fault. There are two types of external, built-in power: AC100 ~ 265V / DC5V switching power supply. Package Includes: 2 Pieces Fiber Optic Converter(3 Pack) 1 Piece Instruction manual(3 Pack)
