EM316-2SFP User Guide
2 Product Overview
The EM316-2SFP transparent converter contains two MSA compliant SFP sockets connected backto-back. No components on the EM316-2SFP board are connected to the data path, so the module is considered transparent. Supported speed ratings range from 100 Mbps up to 2.7 Gbps where speedmatching or multi-rate SFPs are required in both ports. This EM316-2SFP converter is hot-pluggable, and it is managed through the Fiber Driver management bus from a network management module.
The SFP sockets support a wide range of SFP modules available from MRV to address any network situation.
• Single-mode
• Multi-mode
• Multi-rate
• Single fiber bi-directional
• Coarse Wave Division Multiplexing (CWDM)
• Dense Wave Division Multiplexing (DWDM)
• Copper 10/100
2.1 Management features
2.1.1 LIN
Link Integrity Notification (LIN) notifies connected equipment and network management systems if the EM316-2SFP module detects a loss of receive signal on one of its SFP ports. The loss of receive signal may be caused by a cable break, disconnection, remote power loss, or a variety of other events. With LIN enabled on a module, the loss of receive signal is propagated downstream to the remote end, notifying the remote device of a fault in the circuit. This communication ensures that connected equipment is notified of a link fault. The connected device, such as a switch or router, can then activate preconfigured, link-state dependent redundancy mechanisms, and properly react to link conditions. This feature is extremely important in fault-tolerant network designs. To avoid a possible “deadly embrace” condition requiring operator intervention, ensure that neither remote device allows disabling of its SFP transmitter.
LIN works in unmanaged and managed modes, and it applies globally to the module rather than to individual ports. Enable LIN on the module to allow remote control of this feature through network management.
LIN is not supported in a mixed copper and fiber environment.
