Ethernet to VDSL2 Bridge
The VC-234G, a high-performance 4-port Gigabit Ethernet-over-VDSL2 Converter, works well with telephone line networks with a symmetric (downstream/upstream) data rate of up to 190/190Mbps (G.INP, Sym, 8dB) over a distance of 300m and 20/12Mbps over a long distance of 1.4km.
High Performance Gigabit Ethernet over Phone Wire Solution
The VC-234G, a high-performance Gigabit Ethernet-over-VDSL2 Converter, works well with telephone line networks with a symmetric (downstream/upstream) data rate of up to 190/190Mbps (G.INP, Sym, 8dB) over a distance of 300m and 20/12Mbps over a long distance of 1.4km. It is based on the two-core networking technology, Gigabit Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line 2). The VDSL2 technology offers the fastest data transmission speed over the existing copper telephone lines without the need of rewiring.
With integrated support for the ITU-T’s new G.993.5 vectoring technology, the VC-234G works in conjunction with vectoring-enabled DSLAMs to remove crosstalk interference and improve maximum line bandwidth across the existing copper telephone infrastructure.
Implementing with Existing Telephone Copper Wires
The VC-234G is also a Long Reach Ethernet (LRE) Bridge providing four RJ45 Ethernet ports and two RJ11 phone jacks, in which one is for VDSL connection and the other one is for a POTS (Plain Old Telephone Service) connection. The VC-234G has a built-in POTS splitter to share the existing phone line with POTS; therefore, there is no need to replace the existing copper wiring. Just plug the VC-234G into the existing RJ11 telephone jack and a high-performance VDSL2 network can be connected. The VC-234G is ideal to be used as an Ethernet extender to an existing Ethernet network.
Delivering High-demand Service Connectivity for ISP/Triple Play Devices
The VC-234G provides excellent bandwidth to satisfy the triple play devices for home entertainment and communication. With the capability of 240/120Mbps (G.INP, Asym, 8dB) asymmetric data transmission, the VC-234G enables many multi-media services to work on the local Internet, such as VoD (video on demand), voice over IP, video phone, IPTV, Internet caching server, distance education, and so on.
Easy and Flexible Installation
The Ethernet-over-VDSL2 Converter comes with a Plug-and-Play design and is fully compatible with all kinds of network protocols. Moreover, the operating status of each individual port and the whole system can be watched via the rich diagnostic LEDs on the front panel. The VC-234G offers two modes, CPE and CO, for application: CPE mode is used at the client’s side and CO mode is at the central side. The CPE or CO mode can be adjusted by using a built-in DIP switch. For the point-to-point connection, a CPE mode and a CO mode must be set up as one pair of converters to perform the connection.
