This Equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received; including interference that may cause undesired
operation.
CE Mark Warning
This equipment complies with the requirements relating to electromagnetic compatibility,
EN 55022 Class A for ITE, the essential protection requirement of Council Directive
89/336/EEC on the approximation of the laws of the Member States relating to

1. Introductions
The VDS-0202, a VDSL2 (Very high-bit-rate Digital Subscriber Line) Cable Converter,
provides a broadband transmission up to 100/60Mbps of downstream/upstream data rate
over single pair coaxial cable for point-to-point Ethernet connectivity. With 100/60Mbps data
rate, VDS-0202 supports transmission distance up to 400 meters, and 63/27 Mbps for
1.3km long range connection. Users may also select a fixed data rate or a fixed SNR
margin for different coaxial cable ranging.
With plug and play features and minimum installation time, each VDS-0202 can be
configured into either CO for central side or RT for remote side by dip switch setting. The
VDS-0202 conforms to the ITU-T G.993.1 and G.993.2 to meet VDSL/VDSL2 and SG15Q4
DMT for network requirements. A pair of VDS-0202 offers a cost effective solution for
bandwidth-hungry applications such as Cable LAN-to-LAN connectivity, Video Streaming,
FTTB, and MDU/MTU over single twisted pair telephone line.

3. Features
ITU-T G.993.1, G.993.2 VDSL/VDSL2 and SG15Q4 DMT Compliance
100/60Mbps DownSream/UpStream for distance up to 400 meters
Supports VDSL2 connection up to 2000 meters
Line Surge Protection
BNC Connector for Cable interfaces + RJ45 x 2 for Ethernet LAN port
Five LED Indicators
4 Dip Switches for Configuration Settings
Trellis Coding support up to 1024 Discrete Multi-Tone (DMT) bins
Auto MDIX for 10/100 BaseT Ethernet LAN Ports
Low-Latency for Video/Voice/Data applications
Selectable Fast and Interleaved modes
•Fast mode guarantees a minimum end to end latency less than 1 ms.
•Interleaved mode provides impulse noises protection for any impulse noise with a
duration less than 250 us. Interleaved mode has a maximum end to end latency of
10 ms. Interleaved mode is the default mode.
Selectable fixed data rate and fixed SNR margin
•User may select fixed SNR margin (9 dB) or fixed target data rate.
•When fixed SNR margin is selected, the systems will maintain the SNR margin at
9 dB across all available loop length.
•When fixed target data rate is selected, the system will lock the data rate at
50/20Mbps whenever the calculated SNR margin is higher than 9 dB. This will
result in the best system stability and is the default mode.
