Db (Decibel) levels will decrease, causing errors and loss of data. For CAT cables, the standard maximum is 100 meters, anything beyond that will be unreliable.
The decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity. One of these values is often a standard reference value, in which case the decibel is used to express the level of the other value relative to this reference.
The number of decibels is ten times the logarithm to base 10 of the ratio of two power quantities. A change in power by a factor of 10 …
