High Speed ITU-T G.993.5 G.Vectoring and G.INP Ethernet Extender

The Data Connect 2178HSEE-G, a new-generation and high-performance Gigabit Ethernet-over-VDSL2 Converter, works well with a pervasive 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. 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 absolutely the fastest data transmission speed over the existing copper telephone lines without the need of rewiring.

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 2178HSEE-G 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 2178HSEE-G and a CO mode 2178HSEE-G must be set up as one pair of converters to perform the connection.

Via the latest VDSL2 technology, 2178HSEE-G 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 2178HSEE-G works in conjunction with vectoring-enabled DSLAMs to remove crosstalk interference and improve maximum line bandwidth across the existing copper infrastructure.
