The first CableLabs -qualified devices to use DOCSIS Provisioning of EPON (DPoE) specs debuted Mon, featuring interoperability of access network equipment based on Ethernet Passive Optical Network technology. The capability lets cable operators quickly integrate fiber-based access network technology to meet high bandwidth demand by enterprise customers. The devices that passed the tests are from vendors including CommScope, Huawei, Sumitomo Electric and ZTE.

The DPoE specifications enable multi-vendor interoperability of devices, which could allow cable ops to "invest confidently in equipment from multiple vendors that is interoperable with other DPoE-compliant devices," CableLabs said, noting that this level of interoperability didn’t exist prior to the development of the DPoE specifications. More than 20 vendors were involved in the development and interoperability testing of the DPoE specifications.

"When so many equipment suppliers dedicate themselves to interoperability, it helps us increase the speed of innovation within the industry," said Glenn Russell, vp, business services at CableLabs. "Their commitment to interoperability will significantly expand the options for cable operators, as well as the service options for their customers."

DPoE compliant devices support the DOCSIS provisioning process, enabling services to be managed like those delivered over cable modem networks. "It is excellent news for the cable industry to now be able to choose between so many qualified DPoE devices as the complexity and speeds of our offered services continues to increase," said Craig Cowden, svp, network engineering, operations and enterprise solutions at Bright House Networks. "Having qualified devices will provide cable operators with yet another valuable tool as we continue to pursue our respective deployment objectives."
