The following chart illustrates how the performance gain increases over the length of copper loops.
For clarity, we are using the notion of a Bandwidth Improvement Ratio to illustrate the benefits of
installing a BRX-XLR device on a copper pair. The ratio is calculated as the bandwidth using the
BRX-XLR divided by the RAW bandwidth (i.e. without BRX-XLR). For instance, improving a pair from
5 Mbps to 10 Mbps would represent a Bandwidth Improvement Ratio of 2.0 (10 divided by 5).
Note: The curve is based on the use of 26 AWG (0.40mm gauge) copper wire. To convert to larger
cables sizes, simply multiply the loop length by 1.374 for 24 AWG (0.51mm) and 1.844 for 22 AWG
(0.64mm) cables.
