Optical Ethernet Services Demarcation

Optical Ethernet Services Demarcation - 802.3ah

The Fiber Driver^® Optical Ethernet Service Demarcation (OESD) modules from MRV Communications enable service providers to build a fully managed point-to-point fiber optic link with a single manager entity at one end of the link instead of at each end. Using the OAM 802.3ah standard and its specific vendor extensions, they provide management control of both ends of the link from the Central Office (CO) end. The remote CPE ports (user port and OAM port) are managed exactly as if they were local ports on the CO module.

By eliminating CPE management devices and incorporating plug-n-play functionality, the Fiber Driver OESD modules reduce costs of both equipment and configuration. The robust management and diagnostic features include remote loopback, Digital Diagnostics, and remote software downloads. They improve operational expenses by reducing the need for service truck rolls while enhancing customer support to ensure maximum return on all network investments.

OESD modules are available for Ethernet and Fast Ethernet (EM316EFRMAHSH) and Gigabit Ethernet (EM316GRMAHSH) applications. They include solutions for dual fiber, single fiber, and self-healing and redundant links.
