Hitachi Participates in CableLabs® Interop Of DPoE™ Version 1.0

Hitachi Communication Technologies America, Inc. (HCTA), a leading vendor of DOCSIS® Managed EPON access solutions, today announced that they have participated in interoperability testing with the new CableLabs® specification for DOCSIS Provisioning of EPON (DPoE™). DPoE 1.0 specifications were announced at the Cable-Tec Expo in October of 2010. The first interoperability testing was concluded at CableLabs in January and included chip vendors, component vendors and system vendors.

Hitachi is a system vendor that provides a complete DPoE solution called Salira DePON™ which includes Optical Line Terminals, Optical Networking Units and management software. DePON gives cable operators the ability to manage an EPON access network with their existing DOCSIS network management infrastructure.

During the past year Hitachi worked with representatives of leading MSOs and CableLabs to create the DPoE 1.0 specification which was the basis for the recently concluded interoperability testing. Interoperability ensures the cable operators have a selection of vendors that supply DPoE equipment as they begin to deploy the new technology in their regions. Ten vendors participated in the tests for interoperability of DPoE Systems and DPoE ONUs. Interoperability tests for registration, provisioning, OSSI, configuration files and software downloads were part of the test suite. The Hitachi DePON equipment successfully completed the entire test suite.

“By participating in the recent interop at CableLabs, Hitachi provides MSO personnel with another milestone in their plans to deploy high bandwidth business services,” said Jeff Stribling, VP of PLM and Customer Service for Hitachi. “Managing an EPON access network with DOCSIS technology is a significant innovation for the industry and it provides the basis for more efficient and effective service delivery across multiple platform architectures,” he continued.

Hitachi will demonstrate the DePON equipment at this year’s CableLabs Winter Conference in Atlanta from February 28th through March 1st. The DePON system will subsequently be demonstrated at the NFOEC/OFC Conference, March 8th through 10th, in Los Angeles, CA.
