LTS will deploy Hitachi GPON platform to extend Oregon network

MARCH 29, 2007 -- Hitachi Telecom (USA) Inc. (search for Hitachi Telecom) has revealed that its AMN1220 FTTP platform will be implemented by Ledcor Technical Services (LTS) and ComSpan-Bandon Networks to bring the fiber-optic network that is now successfully operating in Bandon, OR, to the town of Coquille. Coquille, a town of approximately 4,000 situated on the Coquille River, lies about 17 miles inland from Bandon.

Construction has already begun, with completion planned for 3Q07. Coquille and Bandon are being connected by fiber-optic cable, which will carry the video feed from the head end located in Bandon to Coquille. LTS and ComSpan-Bandon Networks will offer video, high-speed Internet, and voice services.

"We have developed a business model that brings world-class bandwidth to clusters of smaller communities," claims Ashwin Chitamun, senior vice president of network development for LTS. "Once the basic triple-play services infrastructure—video, high speed Internet, and voice—is established in one location, many of the resources such as the video head end and centralized network operations facilities can be leveraged to economically serve multiple communities. In addition, this investment provides the platform to bring future services to these communities such as home security, telemedicine, videoconferencing, etc."

The AMN1220 FTTP platform is composed of GPON products that provide ultrahigh-bandwidth communication services to residential, business, and institutional subscribers using a single optical fiber direct to the subscriber's premises. Compliant with ITU-T G.984 standards, the AMN1220 provides data rates of 2.488 Gbits/sec downstream and 1.244 Gbits/sec upstream. Hitachi says standards compliance provides assurance that service providers 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 singlemode fiber to optical network terminals (ONTs) 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 GST, a single-family/small-business unit, and the GMT, a configurable multidwelling/multibusiness ONT. According to Hitachi, all of the ONTs can provide a Gigabit Ethernet line-rate interface to the subscriber, enabling a wide range of business applications today and futureproofing for both residential and business networks.
