Quantity :

The BRX-XLR-24 holds 12 BRX-XLR 2-pair modules (with primary lightning protection) for a total of 24 ports / copper pairs. The BRX-XLR-24 comes with a pair of standard 25-pin Amphenol connectors (24 pairs) from the CO/DSLAM and 24 pairs toward the subscriber CPE devices. It includes an optimal pole-mount bracket.

The Broadband Reach Extender – eXtra Long Reach (BRX-XLR) is a fully integrated solution that extends the reach of deployed ADSL2+/ ADSL DSLAMs or MSANs to deliver at least 10 Mbps per pair to subscribers at 17,000 feet (5.2 km) on 24 AWG copper pairs in underserved or unserved markets. An increase in the available bandwidth capacity on existing last mile infrastructure results in higher ARPU, lowered attrition and increased customer satisfaction.

The BRX-XLR offers “new life” for installed DSLAMs and the ‘last mile’ of copper with an optimal way to deliver higher speed services. Broadband Service operators can instantly provide higher bandwidth to subscribers without the heavy expenditures of bringing Fiber to the Home (FTTH).
