Stand alone Managed 10/100/1000Base-Tx to 10/100/1000Base-Fx Media Converter SUN Telecoms stand alone Ethernet Media Converter is offers a cost-effective product to transmit distances up to 120km (Single-mode fiber). It makes it easy to incorporate the advantages of fiber-based connection technology in a managed Ethernet/Fast Ethernet network. Integrated Auto Cross-over MDI/MDI-X and NWay capabilities make it simple to deploy within a network. Also, the í¦hot-swappableí¦ design is ideal for scaling the system up or down quickly. Features: Web, SNMP, Console management Hot-swappable module Available with ST, SC, or WDM Simplex SC single-fiber connectors Auto MDI/MDI-X on copper port Auto-negotiation on copper port LED status for Link/Activity, LFS, 100, Loopback, and Full Duplex/Collision Link-Fault Signaling illuminates to indicate link failure Link-Fault Signaling function can boot up redundant link if network is installed with primary and redundant link Local and remote loopback

Contact: amily[at]veecom dot com dot cn GVE-Tplus is an upgrade of GVE-T. It is based on the ASIC circuitry design technology. It is a multi-functional, multi-purpose E1/G.703 to V.35 and LAN three-in-one multiplexer, which is also knowns as the three-in-one interface converter. GVE-Tplus can not only be set up into GVE-T, but also can distribute the whole E1 capacity to V.35 data interface, although E1 must be framed N*64Kbps(N=1--31). The work mode can be either internal clock and slave-clock, or N*64Kbps(N=1--31) external clock to achieve end-linking line. GVE-Tplus can be set up into long-range Ethernet bridge from V.35 to LAN interface. With low cost, it is suitable for use in bridge connection which is sensitive to cost or use in LAN as a stretcher or subsection. It can learn automatically MAC address in the connected LAN and only transmit the aim address to frame in another LAN. There are more than 10000 addresses in its LAN table. And they can be updated automatically. The highest speed of filtrating and transmission is 30000 frame/second(line speed). The buffer size is 64M. The throughput delay is 1 frame. When it is used as a stretcher or subsection, it can forbid filtration so that all traffic can be broadcasted in WAN. 10baseT interface can run in full duplex Ethernet with topology and improve data throughput by eliminating filled blanks in the 64 bytes frames. Without any negotiation in V.35 port, it is specially suitable for use in satellites and other wireless broadcast. 245mm*215mm*50mm
