Telcos to benefit from Broadcom's RNC devices

Broadcom Corp. has unleashed a reference noise cancellation (RNC) technology enabled by its line-up of BCM63138 devices. The company claims to be the first to give telecom carriers the benefits of RNC to boost the performance of DSL customer premise equipment (CPE) without the need to replace or upgrade installed ADSL or VDSL2 infrastructure equipment.

Broadcom's RNC implementation on its BCM63138 family of high-performance DSL SoCs for home gateways works with existing DSL infrastructure equipment, including single-line or bonded ADSL and VDSL. It also complements existing DSL performance techniques such as G.inp and G.vector, and coexists independent of any other equipment in the network. By filtering out received noise on the subscriber line at the CPE in the residence, this advancement in DSL technology enables carriers to improve the quality of the received signal and deliver higher performing broadband to subscribers, said the company.

Enhancing DSL networks by leveraging the existing installed base of copper networks is the most viable and cost effective option to installing new fibre. RNC reduces noise interference and provides DSL subscribers significant and measurable performance improvements for broadband applications.
