VDSL2 LAN extender

Ordering Information
NV-202  VDSL2 LAN extender





The NV-202 is a low cost LAN extension solution using the G.993.2 VDSL2 standard technology and providing up to 100Mbps 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 100/100Mbps 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-202 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 CO side, PIN1 OFF of DIP Switch is CPE 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-202 may be installed on any level surface (e.g. a table or shelf or rail) that use bracket or DIN rail plate. The NV-202 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-202 supports band profile 17a and 30a, it can automatically detect the cable length and bandwidth depending on the distance to the configuration. The maximum bandwidth is symmetric bandwidth of 100Mbps / 0.3 km.

LAN Distance Extension

Two NV-202 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.


Proper Installation: Train & Metro Stations,Boat and Submarine,Parking system,Weather station,Amusement park,Farm,Jail & Oil Refinery,Telecom.


External Splitter

When you need to use Ethernet and simultaneously use the telephone, You can choose the suitable external splitter in the local. It can be easily installed in the NV-202.
