Fiber Driver™ 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. |
