Long distance two core transmission solution
WD-V101-G
Wd-V101-G is a new generation of DSL broadband network technology that uses digital technology to expand the transmission of existing telephone lines (twisted pair copper wire). Wd-V101-G technology solves the problem of medium distance high-speed transmission, and realizes the demand of industrial field high-speed network through traditional two-core wires. For example: video monitoring, data acquisition, equipment control, etc. Wd-V101-G is divided into CO and CPE to realize point-to-point special line solution, which is widely used in coal mine, factory, railway and other long-distance network transmission.

Functional characteristics
Plug and play, long transmission distance
WD-V101-G is a new generation of telephone line bridge designed and developed by Net Power Technology to solve the problem of long-distance network transmission for customers. The product is easy to install, and the network can be transmitted 2-3 kilometers through CO and CPE connection. Easy to maintain, suitable for long-distance network solutions such as coal mines, factories, and railways.
Plug and play, no setup required.
Rich in features, supports multiple Internet connection modes
Support WEB settings
Support upstream and downstream speed settings
Support IGMP
Adaptability
DMT modulation technology can automatically adjust the rate to adapt to different quality lines, even in the case of noise interference, it can also provide high-performance transmission.
Industrial design suitable for different temperature and humidity environments.
Installation mode
The long-distance two-core transmission solution WD-V101-G can be set to CO and CPE and has different wiring installation methods according to the site environment. If the upstream and downstream bandwidths need to be the same, select the symmetric mode, CO / CPE regardless of direction. If you need a different size of bandwidth, you can choose the following two different installation methods: Downstream bandwidth requirements use method 1, and upstream bandwidth requirements select method 2.
Mode 1 CO Connect the network side CPE connect the user side
Mode 2 CPE Connect the network side CO connect the user side
Flashing (device has not established a connection)
Fast flashing (connection is being established)

Web set up
The computer setting connected to WD-V101-G (CO) is set to: 192.168.1.x (number above 2)
Only need to modify the configuration of CO, CPE does not need to be changed.
Enter http://192.168.1.2/ in the IE address bar of the PC connected to WD-V101-G (CO), then enter the user name and password admin / admin
System message
After entering the user name and password, you can enter the system interface.
You can view the basic information of the current system in the system information under the device information.

SNR surplus modifications
Open "Advanced Settings" in the item bar on the left of the page and then open VDSL2, click the channel settings below, ie
Enter the SNR remaining amount modification interface.
between 6-20, generally recommended to be set to 10, and it will take effect after modification by clicking the application button
Note: the SNR surplus must be an even number. The larger the SNR surplus is, the stronger the anti-interference ability is. However, the bandwidth used for data transmission is relatively narrow and the rate is relatively low. On the contrary, the smaller the SNR surplus is, the weaker the anti-interference ability is, but the bandwidth used for data transmission is relatively high and the rate is relatively high.
Result confirmation
Click "apply" to enter the system information under the device information to view the uplink and downlink rate after the SNR residual is modified.
The figure above shows the uplink and downlink rate with SNR remaining amount of 20
