Broadcom (Broadcom) has announced the launch of new impulse noise protection technology Broadcom® PhyR TM. PhyR helps operators and original equipment manufacturers (OEMs) dramatically improve the quality of voice, data and video services. This new pulse protection solution incorporates Broadcom's ADSL2+/VDSL2 firmware, which greatly improves residual bit error rate (BER) and impulse noise immunity, thereby dramatically increasing the user experience of enjoying voice, data and video convergence services.Video services provided through traditional copper loops are susceptible to interference from noise sources in the surrounding environment, which limits the coverage of the service and may even reduce video quality by inducing "macroblocks". Broadcom's PhyR technology greatly improves noise protection performance without causing limitations in distance, speed, margin, and latency. It is a valuable tool for operators. Physician PhyR technology can greatly reduce the error rate and expand Business coverage, improved reliability and IPTV investment return. Broadcom's PhyR technology has several important advantages over previous impulse noise protection techniques:
Impulse noise recovery performance is increased by 10 times;
Greatly reduce the residual bit error rate or packet loss;
Increased network coverage (increased speed, extended distance, reduced latency)
Simplified network configuration (no need to "adjust" by user)
The central office and client devices can be upgraded by firmware;
It is transparent to the network and upper-layer applications (in terms of networks that use higher-level retransmission methods to improve network efficiency, the burden on the network is greatly reduced).
For all newly deployed and previously deployed central office and customer premises equipment, the firmware of the Broadcom chip solution can be upgraded to the new PhyR firmware. As a result, operators will be able to leverage existing upgrades to deliver existing copper resources that are comparable in quality to Ethernet IPTV and other high-bandwidth applications.
PhyR is currently conducting field tests and system demonstrations to verify the reliability of the technology and its ability to solve real-world problems. At present, field test data shows that the number of error lines is reduced to 1/10, which greatly improves the video quality. Field tests have also shown that the 3dB equivalent coding gain greatly extends the transmission distance of IPTV services, and even the transmission distance of a single data service is extended.
Broadcom's PhyR impulse noise protection and retransmission technology is being widely discussed by many standardization organizations in the industry, and the DSL standard is considering incorporating PhyR technology.
The central office and customer premises equipment chipsets based on powerful digital signal processing technology are very flexible. The new PhyR firmware is based on this flexibility and can be deployed in all new and previously deployed Broadcom ADSL2+ and multimode ADSL2+/VDSL2 chip solutions. Run on. The firmware is providing samples to strategic partners.
