1. V-REBplus

V-REB plus is a 100/10M, self-adaptive, high performance, self-learning, remote Ethernet bridge. With low cost, it is fit for bridge connection or LAN stretcher or subsection. The device can learn automatically MAC address in the connected LAN and only transmit the target address to the frame of another LAN.

There are about 10000 addresses in its LAN table. Those addresses can update automatically. Filtering and forwarding are performed at wire speed up to 30000 frames/second. Buffer is 16M. Throughput delay is 1 frame. When it is used as a stretcher or subsection, it can forbid filtrate to let all the traffic be transmitted in WAN. Its 10 BaseT interface can run under full duplex Ethernet with topology and improve data throughput by eliminating the padding bit in 64 bytes frame.

Variable speed up to 10Mbpson on the WAN line is supported transparently. The line rate may be adjusted in running without any influence to V-REBplus. V-REB plus does not perform any negotiation over the link, which is especially suitable for satellites and other wireless broadcast applications.

Its Ethernet UTP interface has VLAN802.1Q function. It has two transmission modes to choose from: data and image.


  • 100/10M high-speed, high-perfomance, self-adaptive, self-educated long-range Ethernet bridge.
  • LAN comply with: IEEE802.3/IEEE802.3u/ Ethernet interface: UTP(RJ45)
  • WAN interface: V.24/RS232 & V.35 optional
  • Line speed rate of WAN can reache up to 10Mbps.
  • Speed of filtrating and transmitting is up to 30000 frame/ second.
  • Can store up to10000 MAC. And MAC addresses can automatically learning and updating.
  • Ethernet UTP interface conforms to VLAN802.1Q. There are two transmission modes to choose from: data and image.
