Feature: 1. One RJ45 port and one single fiber SC optical port to realize the optical signal conversion between 10/100base TX twisted pair (Ethernet) and 100base FX (optical fiber); 2. Compared with dual-fiber data transmission, core fiber can only use one way to complete signal transmission. Modulus doubled; 3. Comply with IEEE802.3 10Base-T and IEEE802.3u 100Base-TX, 100Base-FX standards; 4. With 10M/100M adaptive capacity; 5. The Ethernet interface can be self-adapted for direct connection/crossover network cable connection; 6. Support full/half duplex mode; 7. Support IEEE802.3X duplex flow control and half-duplex back pressure flow control; 8. 1916 Byte supports large data frames (optional); 9. Built-in lightning protection circuit, which can greatly reduce the damage caused by lightning induction; 10. UTP can reach 100 meters; the longest single-mode fiber is 100 kilometers; 11. There are six LED indicators: Power, TX 100, TX Link/Act, FX 100, FX Link/Act, FDX/Col; easy to monitor The status of the transceiver and determine the cause of the failure; 12. There are two power supply modes: external and internal: AC100～265V/DC5V switching power supply; 13. Working temperature: 0～50 degrees; 14. Storage temperature:-40 ~ 70 degrees; 15. Dimensions: 94mm×70mm×25mm 16. Packing: ESD packing, carton
