2 Giga LAN Over VDSL2 Extender with DIP Switch

Ordering Information
NV-202G  2 Giga LAN Over VDSL2 Extender with DIP Switch





NV-202G is an end to end solution using the G.993.2 VDSL2 standard technology and providing up to 160Mbps symmetric using only a single copper wire pair. Designed specifically or a LAN to LAN extension and supporting both symmetrical and asymmetrical transmission at up to 160/160Mbps within 300 meters and 5/1Mbps at 3000 meters, this is a perfect solution to extend LAN to buildings, hotels, hospitals or any location outside of the 100 meters reach of Ethernet UTP.

Flexible Configuration

The NV-202G supports both central office (CO) and customer-premises equipment (CPE) modes selectable through DIP Switch. Customers can do the configuration for different needs adjustment. PIN1 ON of DIP Switch is CPE side, PIN1 OFF of DIP Switch is CO side.


Interleave delay support

Interleave delay function is used in digital data transmission technology to protect the transmission against noise issue and data error.If during transit more than a certain amount of data has been lost then the data cannot be correctly decoded. Short bursts of noise on the line can cause these data packets to become corrupt and the bridge has to re-request data which in turn can slow down the overall rate at which data is transmitted. Interleaving is a method of taking data packets, chopping them up into smaller bits and then rearranging them so that once contiguous data is now spaced further apart into a non continuous stream. Data packets are re-assembled by your lan extender.

Easy Installation

The NV-202G may be installed on any level surface (e.g. a table or shelf or rail) that use bracket or DIN rail plate. The NV-202G supports plug-and-play installation and is fully compatible with all kinds of network protocols. Furthermore, user can watch the status of each individual port via the LED indicators.

Automatic Bandwidth detection

The NV-202G supports band profile 17a and 30a, it can automatically detect the cable length and bandwidth depending on the distance to the configuration.

LAN Distance Extension

Two NV-202G acting as a standalone pair is good for Ethernet distance extension over existing telephone wires. With just one pair of AWG-24 copper wire, you can easily connect the maximum data rate of 100Mbps and up to 3km distance support. It is easy-to-use which do not requires installation of additional wiring. Every modular phone jack in the home can become a port on the LAN.
