Ethernet Distance Extension

Two VC-234G units, acting as a standalone pair, are good for Ethernet extension over the existing Copper wires. With just one pair of AWG-24 copper wires, you can easily connect two Ethernet networks together with a maximum data rate of 200Mbps. The telephone service can still be used while the VC-234G CO/CPE is in operation. The two solutions listed below are typical applications for the Ethernet over VDSL2 Bridge.

MTU/MDU/Hospitality Solution

The VC-234G is a perfect solution to quickly providing cost-effective yet high-speed network services to multi-unit buildings such as residential buildings (multi-dwelling units), commercial (multi-tenant units) buildings, hotels and hospitals. By utilizing the existing telephony infrastructure, network installation is straightforward and requires no new wiring. With up to 200/100Mbps (G.INP, Asym, 8dB) transmission, VoD, IP telephony and various broadband services can be easily provided.

Last Mile of FTTx Deployment

The VC-234G is an ideal solution for FTTx (Fiber to the Building, Fiber to the Campus or Fiber to the Node) applications. It supports high-bandwidth VDSL2 over the existing telephone wires in the “last mile” from the telecom or Internet service provider’s fiber node to the buildings and customers’ apartments. The 10/100/1000Mbps port of the VC-234G can be directly connected to a PC or Ethernet devices such as Ethernet switches or broadband routers. It is excellent for phone line network built under Internet because every room or house can use the existing phone line to transmit data through the Internet and the whole building can share the Internet to the wider area network at a minimum cost.
