In June, 2006, Hitachi's AMN1220 product family became the first full-rate Gigabit Passive Optical Network (GPON) system to be deployed in commercial service in the United States. ("Full-rate" means 2.4Gbps downstream and 1.2Gbps upstream, twice the speed of earlier systems that were also called "GPON.")
Hitachi's AMN1220 GPON system is a family of high-performance Fiber to the Premises products that provides ultra high bandwidth communication services to residential, business and institutional subscribers using a single optical fiber direct to the subscriber's premises. The AMN1220 is compliant with ITU-T G.984 standards, providing assurance to service providers that they will have maximum flexibility in implementing FTTP solutions as applications and services are added in the future. Legacy TDM services such as T1 are seamlessly handled in their native formats using GPON Encapsulation Mode (GEM) framing.
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 AMN1220 GST, a single family / small business unit, and the AMN1220 GMT, a configurable multi-dwelling/multi-business ONT. All ONTs can provide a Gigabit Ethernet line rate interface to the subscriber, enabling a wide range of business applications today and providing future proofing for both residential and business networks.
The AMN1220 provides triple play services and more, including:
