Function 1. One RJ45 port and a single SC fiber optic 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. Complies with IEEE802.3 10BaseT and IEEE802.3u 100BaseTX 100BaseFX standards. 4. With 10M/100M adaptive capability. 5. Ethernet interface can self-adapt for direct connection or crossover network cable connection. 6. Supports full/half duplex mode. 7. Supports IEEE802.3X duplex flow control and half-duplex backpressure flow control. 8. 1916 Byte supports large data frames optionally. 9. Built-in lightning protection circuit, which can greatly reduce the damage caused by lightning strikes. 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, making it easy to monitor the status of the transceiver and determine the cause of the fault. 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. Packaging: ESD packaging carton.
