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.

 

G.INP / G998.4

G.998.4 is a newer alternative to FEC (Forward Error Correction) and interleaving to providing a lower overhead (FEC loses about 12% whereas G.INP only corrects errors when they actually occur) so there is little overhead. G.998.4 was formerly known as G.INP and may also be referred to as Impulse Noise Protection or Physical Retransmission (PHY-R).
G998.4 operates at the physical layer. The transmitting modem keeps a copy of transmitted data in a retransmission buffer. If the receiver detects corruption (by way of a checksum) a retransmission is requested. If the transmitter responds in time, the data is repaired. The round-tip time of a retransmission should be <4ms. If the transmitter doesn't retransmit in time, the corrupt data is forwarded for higher level protocols to sort out.

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.

APPLICATIONS

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.
