Impact of low insulation resistance
Impact of low insulation resistance
(OP)
Hi!
I would like to know in detail about the impact of low insulation resistance in the Copper transmission line on the telecommunication network. What would be probable impoact on the signal if the Cu cable in the network ie. between the subscriber and the exchange has low insulation resistance( 150Mohms-km to 1.3Gohms -km)?

RE: Impact of low insulation resistance
As far as data is concearned, lets say ADSL running at 1Mb. Low insulation will have a tremendous effect. Anything less than a perfect pair will not allow maximum transmission rate. Usually, anything above 30 Meg ohms is considered perfect (with no ground conductivity). However, there are many more factors, other than pair insulation that affect transmission rate.
150M ohms to 1.3 G ohms would almost be considered an open pair and is very rarely encountered in the field.

You may check BICSI's manual and TIA/EIA standards to learn more about this.
