FCC Certifications 

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 

electromagnetic compatibility.

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.

„

 

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.
