(Supply hotline: 020-29049138 Mobile: 13726845808 QQ: 1175560433 Contact: Mr. Wu)? Agent D-LINK fiber optic transceiver series There are: DFE-850 Fast Ethernet D-LINK Fast multi-mode fiber converter, DFE-851 Fast Ethernet D-LINK Fast single-mode fiber converter, DFE-852 Fast Ethernet single-mode fiber optic converter D-LINK , DFE-855 D-LINK Fast Ethernet media converter, DMC-515SC D-LINK Fast Ethernet media converter. DFE-851 Fast Ethernet single-mode fiber Fast Ethernet converter able to convert the signal, the signal fiber media conversion from copper twisted pair media signal. Support IEEE802.3U 100Base-TX / FX, support full-duplex or half-duplex mode, you can convert 10BASE-T / 100BASE-TX Fast Ethernet twisted-pair signals to 100Base-FX Fast Ethernet fiber signals and provide a twisted-pair RJ- 45 port and a fiber optic interface. Different office buildings or isolated twisted-pair Ethernet devices can use this kind of media converter to connect. Media converters can be connected by twisted-pair cable between the method to increase the length of twisted pair, on which the converter is a single-mode SC fiber port interface that supports up to cable length 15km. DFE-851 is a solid metal casing, LED status indicators and AC to DC power adapter, can be used independently as a converter. The converter is compact design, easy to use, can be used with other supporting the use of different network devices together. The equipment may be used in switches, routers, servers, print servers, and so on.
