Chip major Broadcom announced VDSL2 35b and G.fast bonding support for two new protocols under development in the International Telecommunication Union (ITU).
Broadcom made the announcement at the Broadband World Forum 2015.
Broadcom — with support for these new standards — is enabling DSL network operators with a long-term roadmap for competitive high-bandwidth services with minimal investment to their physical plants.
The new 35b protocol is an optimal solution for telecom operators with a significant investment in Fiber to the Cabinet (FTTC) architectures to leverage the benefits of VDSL2 vectoring at higher data rates.
By engineering the tone structure of 35b to remain consistent with the VDSL2 17a protocol, this new standard increases aggregate DSL performance by up to 100 percent, without disturbing G.Vector crosstalk cancellation technology.
Broadcom previously released BCM63138 integrated residential gateway and BCM65235 Central Office DSP.
Greg Fischer, senior vice president and general manager, Broadband Carrier Access, said: “The quick introduction of end-to-end technology in support of 35b will have a very meaningful impact in time-to-service for this important new protocol.”
The new G.fast protocol remains a compelling alternative to avoid or defer the expense of installing fiber directly to the home. To maximize the distance over which multi-gigabit copper services may be delivered, the ITU recently developed a multi-line bonding amendment to the G.9701 standard.
By aggregating multiple copper pairs into a single logical link, bonding provides a path to increase rates well beyond 1Gbps, an important objective for many providers in competitive broadband markets. Broadcom is supporting a solution for G.fast bonding utilizing the existing BCM65244 Central Office DSP with BCM65249 bonded CPE PHY device.
“With Broadcom’s strong commitment to the G.fast standard, including the new G.fast bonding standard, we are seeing the potential to deliver a cost-effective, long-term gigabit roadmap for copper networks,” said Mu-Piao Shih, president of Chunghwa Telecom.
