3.3 BRX-XLR Placement Flexibility
Over and above the performance gains, one of the major advantages of the BRX-XLR over other
products is that its placement along the loop is very flexible and does not impose hard constraints
when choosing the location where it should be installed. For instance, on a 26 AWG (0.4mm) loop of
12,500 feet / 3.8 km, placing the BRX-XLR anywhere between 6,000 feet / 1.8 km and 9,000 feet /
2.7 km away from the DSLAM will deliver 10 Mbps to the customer.
In fact, the BRX-XLR is designed to offer very similar performance gains whenever it is deployed at a
distance that ranges from 45-75% of the total loop distance (away from the DSLAM). The graph
below illustrates the
minimum
performance gain that can be expected when the BRX-XLR is placed
anywhere in this range.
