Figure 2: Downstream Improvement Ratio vs Loop Length (meters)
The table below illustrates a few examples of the bandwidth increases one can expect with the
insertion of a BRX-XLR:

Table 1: Downstream Performance Increase Examples (Typical Lines)
Another way to view the benefits of the BRX-XLR is to look at the graph below which demonstrates
the actual bandwidth performances (with and without BRX-XLR) as it relates to loop length using 26
AWG / 0.4mm copper gauge. Again, to convert to larger cable sizes, simply multiply the loop length
by 1.374 for 24 AWG (0.51mm) and 1.844 for 22 AWG (0.64mm) cables.
