Overview
The Fiber Driver(R) 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-nplay 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.

Management features common to all the Fiber Driver OESD modules include Last Gasp, LIN, and remote loopback. Last Gasp allows the module to send a management alert before shutting down in the event of power loss. With LIN enabled, loss of link on any port of a module disables all downstream AH ports. Devices dependent on the link status can react to the problem, which is critical in mission critical network designs. Remote loopback can test and verify the integrity of the entire link. Every Fiber Driver OESD module is upgradeable to the latest features and standards available by remotely downloading the microcode and firmware. The OESD modules are compatible with any powered Fiber Driver chassis and they fit into a single slot. Each module includes an auto-sensing 10/100 Mbps RJ-45 data port that also features automatic MDI/MDIX selection. The SFP ports support Digital Diagnostics (SFF-8472), and they may be configured with any of the wide range of SFP interfaces available from MRV.
Self-healing and redundant link versions of the Fiber Driver OESD modules are standard for mission critical applications. Both single-homed and dual-homed configuarations are supported. The redundant link feature includes primary and secondary interfaces for both the OAM and trunk ports. If the active link fails, the module automatically switches to the secondary path. The switchover time is less than 100 nanoseconds with parallel links, so the event remains transparent to the network and eliminates loss of service and data. Fiber Driver OESD modules support the full range of shorthaul, long-haul, dual-fiber, single-fiber, Fast Ethernet, and Gigabit Ethernet SFPs available from MRV.
