Broadcom demonstrated its New PhyR (newfire) technology at NXTComm this week claiming that it delivers a ten fold improvement in noise resilience in DSL. Any improvements in bit error rate that technologies like this can deliver are likely to be immediately embraced by any Telco trying to deliver HD video over its DSL lines, which at present suffer multiple visual artifacts per hour due to noise and deformed packets.
Broadcom today announced a new impulse noise protection technology that enables carriers and OEMs to dramatically improve voice, data and video services to their customers. Broadcom also reckons that this will extend the distance from the central exchange that high speed data can be delivered, taking broadband down longer loops.
Broadcom says that its PhyR technology improves noise protection without introducing limitations of reach, rate, margin or latency. It also does away with the need for individual line tuning. All Broadcom equipment at central offices and CPE silicon can be firmware upgraded to new PhyR firmware.
PhyR field trials and system demonstrations are currently underway as a means to validate the robustness of the technology and its ability to address “real-world” issues. The company claims that field trials show a ten-fold reduction of errors and a 3dB gain.
