    This Ethernet over VDSL2 Converter from PLANET Technology is a high-performance Gigabit Ethernet-over-VDSL2 Converter that works well with a telephone line network with a symmetric data rate of up to 200/160Mbps (G.INP, Sym, 8dB) over a distance of 300m and 20/12Mbps over a long distance of 1.4km. The VC-231G is based on the two-core networking technology, Gigabit Ethernet and VDSL2 (Very-high-data-rate Digital Subscriber Line 2). VDSL2 technology offers the fastest data transmission speed over the existing copper telephone lines without the need of rewiring.

    High-performance Ethernet over VDSL2

    Via the latest VDSL2 technology, PLANET’s VC-231G offers high-speed access to Internet, up to 190Mbps for both upstream and downstream data transmissions. With integrated support for the ITU-T’s new G.993.5 vectoring technology, the VC-231G works in conjunction with vectoring-enabled DSLAMs to remove crosstalk interference and improve maximum line bandwidth across the existing copper infrastructure.

    Implementing with Existing Telephone Copper Wires

    The VC-231G is also a Long Reach Ethernet (LRE) converter providing one RJ45 Ethernet port and one RJ11 phone jack, which is for VDSL2 connection. Use the additional splitter from the package of the VC-231G to share the existing phone line with POTS, thus replacing the existing copper wiring is not necessary. Just plug the VC-231G with the additional splitter into the existing RJ11 telephone jack and a high-performance VDSL2 network can be connected. It is ideal for use as an Ethernet extender to an existing Ethernet network.

    Delivering High-demanding Service Connectivity for ISP/Triple Play Devices

    The VC-231G provides an excellent bandwidth demand for triple play devices, home entertainment and communication. With the asymmetric data transmission of 220/120Mbps (G.INP, Asym, 8dB), the VC-231G 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 many network protocols. 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-231G offers two modes, CPE and CO, for application — CPE mode is used at client side and CO mode is at central side. The CPE or CO mode can be adjusted by using a built-in DIP switch. For point-to-point connection, a CPE mode VC-231G and a CO mode VC-231G must be set up as one pair of converters to perform the connection.

    ADSL2+ Fallback

    For those ISPs that still provide ADSL broadband service, the VC-231G can support transmission rates up to 24Mbps downstream and 1Mbps upstream with the ADSL2+ technology. The VC-231G establishes a connection with ISP and can be also directly switched over to VDSL2 after the ISP network upgrade.
