VDSL2 LAN extender with PoE

Ordering Information
NV-202P VDSL2 LAN extender with PoE





The NV-202P 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 for 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 with PoE for IP Surveillance or PoE powered devices at any location outside of the 100 meters reach.

Flexible Configuration

The NV-202P 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-202P may be installed on any level surface (e.g. a table or shelf or rail) that use bracket or DIN rail plate. The NV-202P 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-202P 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

User can use NV-202 bridge (CO mode) to connect NV-202P bridge (CPE mode), or use NV-202P bridge (CO mode) to connect NV-202 bridge (CPE mode) that to do a variety of applications. The bridge’s line port supports 100Mbps maximum for data service across existing phone wiring. It is easy-to-use which do not require installation of additional wiring. Every modular phone jack in the home can become a port on the LAN. Network devices can be installed via a telephone wire in any suitable distance.(depending on the speed)


Proper Installation: IP surveillance、Call center、Telecom.


IP Surveillance

If user need use over 1.5 km cable length and also need bigger bandwidth application, such as connect to ip camera. User can use NV-202P (CO mode) and NV-202 (CPE mode) to achieve the IP surveillance for long distance application.
