The Optical Communications Systems (OCS) division of MRV Communications, a Calif.-based provider of optical communications network infrastructure equipment and integration and managed services, recently participated in interoperability testing with the new CableLabs specifications for DOCSIS Provisioning of Ethernet Passive Optical Network (DPoE).

During the event, MRV OCS showcased its OptiSwitch Carrier Ethernet Access solution and worked alongside other vendors, demonstrating a high level of interoperability between eight DPoE Systems, seven DPoE ONUs, and four Ethernet Demarcation Devices, the company notes. The event focused on PON-layer registration, provisioning, and operational systems support interfaces.

“Interoperability will play a critical role as service providers expand their networks and enrich their Ethernet services offerings to meet the demand for additional bandwidth capacity driven by high-bandwidth applications such as IPTV, streaming video, peer-to-peer networking and content-rich websites continues to grow," said Barry Gorsun, president of MRV’s OCS division, in a statement.

DPoE 1.0 specifications were announced at the Cable-Tec Expo last October, and the interoperability testing was concluded at CableLabs in late January. CableLabs events provide vendors with an informal setting to test the ability of their products to interoperate with other devices in an end-to-end system.

Version 1.0 of the DPoE specs provided the basis for the interoperability event, providing requirements for EPON equipment to be provisioned using current DOCSIS provisioning systems and service concepts. The specs also define requirements and functionality to support MEF Ethernet Private Line service for business customers.
