| MRV Products EM316xSH - Self Healing/Redundant Link Converters  Fiber DriverT Self Healing/Redundant Link modules are for mission critical applications that demand maximum uptime. These modules have one copper input and two fiber outputs. One functions as a primary path and the other as a secondary path. In the event of a link loss, the data will be automatically switched from the primary path to the secondary path. The secondary path can also be used for routing based on time of day parameters under the control of the management system. These modules use a link detect mechanism that switches over to the secondary link in microseconds directed by circuitry on the module itself. Doing this without any OSPF or Spanning Tree induced network topology modification eliminates long reconvergence times and removes the possibility of data loss. If the secondary path fails, an alarm will be generated by the management system indicating that there is no redundancy available. This information is gathered regardless of the status of the network. Self Healing/Redundant Link modules are offered with Dual Fiber and Single Fiber links. This provides the same copper to fiber conversion while gaining link redundancy using the existing fiber pair. Self Healing/Redundant Link Modules help service providers fulfill Service Level Agreements. They are also used in Enterprise networks where the cost of downtime requires redundancy. |
