Japan Cablenet taps into 160 Mbps speeds with Arris
Arris said that Japan Cablenet Ltd. (JCN), the country’s second-largest cable operator, will begin wide-scale deployment of its 160 Mbps high-seed data service across its cable system footprint, beginning at its JCN Koala Katsushika site this month.
The service, which is called "Speed Star 160,” is also noteworthy because it will incorporate what is believed to be the industry's first deployed service using upstream channel bonding technology, which greatly enhances data rates.
In North America, Comcast and Rogers are both interested in deploying DOCSIS 3.0-enabled upstream channel bonding (story here).
DOCSIS 3.0 can achieve downstream broadband speeds of up to 160 Mbps by bonding 6 MHz – or in the case of Europe and some parts of Asia and Latin America, 8 MHz – channels together. DOCSIS upstream channel bonding can provide up to 120 Mbps of shared throughput for cable operators.
Japan Cablenet is using Arris’ cable modem termination system (CMTS) in order to deliver ultra-fast wideband data service to its customers. The Arris CMTS platform consists of the DOCSIS 3.0-qualified C4 CMTS and the DOCSIS 3.0-certified WBM760C wideband modems, capable of delivering data speeds of up to 160 Mbps, along with carrier-grade voice service.
The sale of the integrated CMTS platform was conducted with the assistance of Arris resellers Net One Systems and KDDI.
"We are very excited to be the first network in Japan, if not the world, to deploy upstream channel bonding for our high-speed data customers," said JCN general manager of business planning department and DOCSIS 3.0 project manager Hiroyoshi Takeyama. "This critical feature will make activities like the sharing of family pictures, home movies or other user-generated content a far more satisfying experience for our subscribers. It is our mission to provide our customers with the world's fastest, most secure and most reliable super-high-speed data service."
JCN provides residential broadband services through 17 system operators in the Tokyo metropolitan region of Japan. It was founded in March 2001, and its major shareholders are KDDI Corp. and Tepco.
