Feature: 1. . 2. An RJ45 ports and a single-fiber SC optical port , to achieve optical signal conversion between 10/100/1000base TX twisted pair (Ethernet )and 1000base FX (fiber optic) ; 3. Core optical fiber can be completed in just one way signal transmission compared to dual fiber optic data transmission mode to improve the quantity doubled ; 4. Compliance with IEEE802.3 10Base-T and IEEE802.3u 1000Base-TX, 1000Base-FX standards ; 5. Has 10M/100/1000M adaptive capacity ; 6. Ethernet interface can adaptively direct line / crossover cable connection ; 7. Support full / half duplex mode ; 8. Support IEEE802.3X duplex flow control and half-duplex backpressure flow control ; 9. Supports broadcast storm prevention function ; 10. 1916 support large data frame ( optional ) ; 11. Built- in -protection circuit , which can greatly reduce the damage caused by induction ; 12. UTP up to 100 meters ; 100 km single-mode fiber ; 13. There are six LED indicators: Power, TX 1000, TX Link / Act, FX 1000, FX Link / Act, / Col; easy to monitor the working status of the transceiver and determine the cause of the fault Working temperature: 0 ~ 50 degree Storage temperature: - 40 ~ 70 degree outer Dimensions: 95mm x 71mm x 25mm For the environment: For telecommunications , broadcasting, broadband fiber optic network data traffic and the need to improve performance, high-reliability network environment.
