Broadcom announced a new impulse noise protection technology it's calling PhyR ("fire"), which incorporates the company's ADSL2+/VDSL2 firmware and provides a significant improvement in residual bit error rate (BER) as well as resistance against impulsive noise.
IPTV deployments require carriers to provide a certain acceptable level of impulse noise protection and margin settings, which in turn determine an achievable data rate and the loop length over which voice, video and data or IPTV services will be delivered. Increasing noise protection in current IPTV deployments has an improved effect on residual errors, Broadcom explained, but has an adverse effect on the serviceable reach and data rate, thereby limiting the service coverage area.
Broadcom said its PhyR technology significantly improves noise protection without inducing limitations of reach, rate, margin or latency. PhyR firmware is sampling to early access partners and will be demonstrated next week at NXTComm 2007.
