What is a good line attenuation value?

What is a good line attenuation value?

What is a good line attenuation value?

The higher the value of this parameter, the lower the line quality and, therefore, the lower the data transfer/receipt speed. Optimal values should be between 5 and 30 dB (excellent or good line). An attenuation value of 45 dB or higher means that the line is not suitable for ADSL.

What is attenuation in DSL?

Line attenuation (loss) is a measure of how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB, the better for this measurement.

What bandwidth is used for VDSL?

VDSL offers speeds of up to 52 Mbit/s downstream and 16 Mbit/s upstream, over a single twisted pair of copper wires using the frequency band from 25 kHz to 12 MHz.

Is VDSL fiber-optic?

VDSL (Very High Speed Digital Subscriber Line) is the best known yet, but basically only partially fiber-optic based. In this variant, fiber optic cables are laid from the switchboard to the cable distribution system (DSLAM).

How do I reduce attenuation on ADSL line?

How to Reduce Line Attenuation For DSL

  1. Change the network and connection cables running from your cable to your modem.
  2. Switch the cables running from your modem to the main source of power in the building you are in.
  3. Check that the phone line is connected to a DSL/POT splitter before entering the phone jack.

How can I improve my DSL attenuation?

How to Reduce Line Attenuation For DSL

  1. Change the network and connection cables running from your cable to your modem.
  2. Switch the cables running from your modem to the main source of power in the building you are in.
  3. Find the phone jack where your modem connects to the phone line in your building.

How does distance affect attenuation?

Finally, the distance between the signal’s source and the end user is also a potential cause for attenuation. The further a transmission has to travel, the more noise it can experience along the way, thus causing attenuation. Even wireless signals will begin to lose strength the farther the signal has to travel.

Can VDSL reach 100 Mbps?

VDSL Speeds VDSL downstream and upstream speeds can reach up to 100 megabits per second (Mbps). VDSL2 can actually reach theoretic data rates of up to 200 Mbps.
