VDSL2 Broadband Reach Extender (BRX-VDSL2)

The BRX-VDSL2 is a performance and distance (reach) amplifier that extends the reach of VDSL2 DSLAMs / MSANs by up to 2,250 feet (685 m) and significantly expands the Customer Serving Area (CSA). It delivers 25/3 Mbps up to 6,500 feet (2 km) on one pair and 50/8 Mbps up to 6,500 feet (2 km) on 2 pairs. It is installed between the DSLAM and the remote CPE and increases the bandwidth available to business and residential customers. The BRX-VDSL2 has a broad placement flexibility to efficiently re-use existing splice points in the copper Outside Plant (OSP).

The BRX-VDSL2 fills the gap when fiber is not cost effective. It can be used on single pairs and is fully transparent to pair bonding. It delivers a fiber-like user experience so customers can enjoy top quality video streaming with multiple HD feeds and still have enough bandwidth to simultaneously surf the web and use other applications. The increase in the available bandwidth capacity on existing last mile infrastructure results in higher ARPU, lower attrition and increased customer satisfaction at a low cost.

Benefits of the BRX-VDSL2

100% Transparent Support for Vectoring and Pair Bonding

The BRX-VDSL2 is fully transparent to Vectoring and pair-bonding applications. Installing a BRX-VDSL2 on a copper pair makes it possible to extend the benefit of vectoring up to 6,000 feet (1.8 km) from the DSLAM, well beyond the typical range of 3,000 feet (1 km) where vectoring is usually effective.

While the use of vectoring is strongly recommended, amplification of a pair with the BRX-VDSL2 offers better performance than vectoring alone. Bonding two pair together enables the delivery of 50 / 8 Mbps service to customers located over 6,500 feet (2 km) from the DSLAM.

More than Signal Amplification

In addition to delivering a significant increase in performance, field testing has shown that the BRX-VDSL2 will help mitigate some of the common problems impacting the performance in the Outside Plant (OSP).

As it amplifies the VDSL2 signal, it filters out some of the accumulated noise on the copper pair which improves the signal-to-noise ratio (SNR). It also mitigates the impact of bridge taps, including those resulting from inadequate in-house wiring. The BRX-VDSL2 automatically detects and supports the EU-32 mode (equivalent to ADSL2+ Annex A) and the EU-64 mode (equivalent to ADSL2+ Annex M) for the U0 band where there is a need for more upstream bandwidth.
