Good line attenuation
WebMay 22, 2024 · Very good accuracy is obtained if the length of a subsection is no more than one-twentieth of a wavelength. The full transmission line model is the cascade of many transmission line subsections (e.g. see Figure \(\PageIndex{2}\)). ... The characteristic impedance for minimum attenuation in an air-filled line is \(77\:\Omega\), with a … WebAttenuation on the line doesn't directly turn into distance, it's just proportional. 5m of brand spanking new copper will have much lower attenuation than 5m of old corroded and half submerged copper. If you didn't know their condition or length and simply measured the attenuation, you'd assume the new one was shorter.
Good line attenuation
Did you know?
WebAttenuation is the reduction in signal strength on your line, sometimes also refered to as "loop loss". While it is related to the length of the line from the exchange, it varies depending on the actual wire gauge, material, as well as the frequency. WebMay 24, 2024 · The ‘Noise margin’ value should be 6 dB and higher. 11 dB to 20 dB is a good line, no problems with synchronization; 21 dB to 28 dB is a very good line; 29 dB and above is a perfect line. What is line attenuation? Line attenuation (loss) is a measure of how much the signal has degraded between the DSLAM and the modem. The lower the …
WebApr 4, 2014 · This rule of thumb enables us to estimate the attenuation at the Nyquist for a lossy, uniform channel. Attenuation figure of merit: 0.2 dB/inch/GHz, for a lossy channel, 0.1 dB/inch/GHz for a low loss channel. Remember: Before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of thumb wisely. Previous: Rule of … WebApr 25, 2024 · The attenuation depends on the cable length between the ADSL modem and the DSLAM. The higher the value of this parameter, the lower the line quality and, …
WebNov 27, 2024 · 30dB – 40dB is very good; 40dB – 50db is OK; 50dB and above is bad; SNR Margin is a value to set in order to get the speed you … WebDec 22, 2024 · Use the TIA/EIA maximum loss as 0.3 per splice and the total splice loss is 0.3dB × 1=0.3dB. Calculate the other component loss if there are any other components such as attenuators. Add the cable loss, connector loss, and splice loss and get the total link loss. The total loss for this link is 5dB + 1.5dB + 0.3dB = 6.8dB.
WebSep 30, 2006 · Upload hasn't changed, but line attenuation downstream has decreased by like 2.5dB That'll be good for when you get ADSL2+. My line attenuation has never changed, except when I went onto iiNet DSLAM where my downstream attenuation went up by 1 dB and my upstream attenuation when up by around 14 dB - almost doubling.
