Broadcom Intros DOCSIS/Euro-DOCSIS 3.0-Based Chips for Next Gen CMTS
By Anuradha Shukla, TMCnet Contributor
Broadcom has launched the industry's first DOCSIS 3.0/Euro-DOCSIS 3.0-based chipset with advanced line rate capabilities for next generation cable modem termination systems (CMTS).
Cisco Systems has already announced their plan to incorporate one of Broadcom's (News - Alert) newly announced solutions in their next generation CMTS equipment.
By working in conjunction with the recently launched Broadcom BCM3380 - the industry’s first fully integrated cable modem solution for DOCSIS 3.0/Euro-DOCSIS 3.0 applications, Broadcom’s new CMTS chipset provides the first end-to-end solution for enabling interactive services over broadband cable services, with reverse path speeds up to 160 Megabits per second (Mbps) and downstream speeds up to 400 Mbps.
What makes the Broadcom's DOCSIS 3.0 CMTS and cable modem chips unique is the TurboQAM technology. The company claims this technology provides a 33 percent improvement over reverse path speeds and a 25 percent improvement over downstream speeds in support of the DOCSIS 3.0 standard.
Broadcom’s new DOCSIS 3.0 CMTS chipset is expected to allow cable operators to cost effectively upgrade their headend equipment to manage faster line speeds for broadband services requiring greater than 100 Mbps of upstream and downstream bandwidth.
Leveraging reliable, symmetrical network services using equipment based on Broadcom's advanced DOCSIS 3.0-based CMTS chipset, cable operators can also successfully broaden their subscriber bases to include business customers.
Ernie Bahm, senior director, CMTS Product Marketing for Broadcom's Broadband Communications Group, explained that in conjunction with the BCM3380 cable modem solution, these products provide a complete end-to-end DOCSIS 3.0-based silicon solution with advanced capabilities. These help the cable operators to economically and reliably expand their broadband services to support high value interactive applications for both residential and commercial customers.
Broadcom made this announcement at 2009 International Consumer Electronics Show where the company also demonstrated alternative MAC and PHY (AMP) technology that enables Bluetooth to support data rates of up to 24 Megabits per second (Mbps) and a significant increase in range by using other wireless radio technologies, such as 802.11, as its transport medium.
