Copper Backhaul

To address the growing demand for telecommunications infrastructure capacity, Xtendwave has developed a cost-effective solution for achieving increased data throughput in the crosstalk-constrained copper-based cellular and business-access backhaul networks. VDSL2 has become the standard for delivering broadband, triple-play services to consumers. However, carriers avoid the use of the spectrally efficient VDSL2 for business access and backhaul because of its vulnerability to alien interference. Xtendwave’s technology addresses this vulnerability by effectively mitigating interference, even in the case of strong alien interferers. The company’s key innovation is in non-iterative, reduced-complexity, dynamic interference cancellation algorithms which greatly enhance performance while requiring minimal silicon area in VDSL2 multi-channel modems. Xtendwave anticipates that this technology will be widely incorporated in copper-based equipment.

Key features of Xtendwave’s solution:

  • Supports the use of VDSL2 for copper backhaul in the presence of strong alien interference
  • Compatible with vectored DSL
  • Low latency
  • Efficient algorithms, enable cost-effective implementation
  • Ready to be implemented in VDSL modem designs
