At an April interoperability testing event focused on DOCSIS Provisioning of EPON (DPoE), 13 industry suppliers converged on CableLabs to participate. The second DPoE interop event attracted five new suppliers while overall participation increased 30 percent. Suppliers participating in the event included Adva, Arris, Atheros, Broadcom, Ciena, CommScope, CTDI, Finisar, Huawei, MRV, Sumitomo, Telco Systems, and ZTE.

The interop focused on the DPoE v1.0 specifications. In addition to providing provisioning requirements for Ethernet Passive Optical Network (EPON) equipment, version 1.0 of the DPoE specifications defines requirements and functionality to support Metro Ethernet services such as Ethernet Private Line (EPL).

“Significant progress has been made since the first interop event," said Curtis Knittle, director of Digital Video Services at CableLabs, in a statement. "This interop featured several combinations of equipment from multiple suppliers to create a DPoE network that supports Metro Ethernet services. For these network services, all devices were provisioned using the same back-office systems normally used to provision DOCSIS equipment.”

The next interoperability event for DPoE products is scheduled for August 22.
