Hitachi Introduces Gigabit Passive Optical Network System
Wireless/Networking | Just Announced
Tue 04 Oct 2005



ATLANTA, Oct. 3, 2005-- Hitachi and Hitachi Telecom (USA) announced details of the company's new AMN1220 family of GPON optical access solutions. Compliant with all ITU-T G.984 standards and FSAN recommendations, the AMN1220 provides data rates of 2.488Gbit/s downstream and 1.244Gbit/s upstream. The product is based on GPON Encapsulation Mode (GEM) framing, allowing TDM services such as T1 to be handled in their native formats. The AMN1220 will be generally available in the first quarter 2006.

The AMN1220 consists of a centrally located Optical Line Terminal (OLT) connected via single-mode fiber optic cable to Optical Network Terminals (ONT) at the subscribers' premises. The OLT is equipped with a hybrid Layer 2/3 + TDM switch fabric for flexible traffic management and consolidation. ONTs include the SFU, a single family / small business unit, and the MXU, a configurable multi-dwelling / multi-business ONT. All ONTs can provide a Gigabit Ethernet line rate interface to the customer, enabling a wide range of business applications today and providing future proofing for both residential and business networks.

The AMN1220 provides triple play services -- video, data and voice -- but goes much further. Optional support for RF Video allows flexibility in choosing a video technology. Robust support for VLAN services enables private network service offerings. Integrated bandwidth management and QoS capabilities provide the ability to offer a full range of tiered services. Native support of T1 traffic allows network providers to continue to serve existing TDM customers on the same network nfrastructure. Integrated VoIP technology in the ONTs allows a much lower cost and more feature-rich voice services offering without complicated external devices. Other applications such as Gigabit Ethernet backhaul, remote Ethernet extension, and multiple business offerings can be configured and supported using the large bandwidth and high degree of flexibility provided by the AMN1220.

"Many service providers will find Hitachi's new GPON system to be a powerful and timely offer," said Dr. John Ryan, president & co-founder, 10th Street Advisors. "We're interested in how it builds on a legacy of large-scale deployments in Japan, yet brings key carrier-class attributes important in North America. Specifically, while it supports futuristic, high-bandwidth services, it also provides the basics, like narrowband T1, and DS1-to-OC3 aggregation and grooming."

"We believe that the AMN1220 GPON System will be an excellent choice for deployments of all sizes," said David Foote, Hitachi Telecom CTO. "For smaller networks, we provide a modular growth path in both the common and traffic components of the OLT, minimizing the startup cost of the network. We also benefit from our high volume manufacturing capability, extensive and successful FTTP network experience, and vertical integration developed to handle the Asia-Pacific market, allowing us control over the quality of every component of our system." Continued Mr. Foote, "For large regional deployments as well as nationwide deployments, our carrier-class Network Element Management System provides the extensive management features that carriers require."
