Overview
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 vendor extensions, they provide management control
of both ends of the link from the Central Office (CO) end. The remote
CPE and OAM ports are managed 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-5) and for Gigabit Ethernet (EM316GRMAHSH-5)
applications. They include solutions for dual fiber, single fiber, self-healing
links, and redundant trunk configurations.
These modules deliver the full functionality of an optical Ethernet data
channel to the end user - including support for packet sizes of up to 1900
bytes - while providing the management features required by service
providers. They offer rate limiting at a resolution of 32 kbps for Ethernet
and Fast Ethernet data channels and at 1 Mbps for Gigabit Ethernet data
channels, enabling multi-tiered service plans.
