Transportation Resilient Ring Application
Transportation Resilient Ring Application
Fiber optic links provide the long-distance connectivity required in transportation control networks. In this Ethernet network application, fiber is used in a ring topology to connect control stations along a commuter train route.
The UTP cable from the router at the Network Core or Point of Presence is converted to fiber with an iConverter standalone 10/100M2 media converter with integrated management (also known as a Network Interface Device, or NID). This fiber link connects to an iConverter 2-Module Chassis with two iConverter 10/100M2 plug-in media converter modules.
The media converters share data via the chassis Ethernet backplane and provide two fiber ports and two UTP ports. The 2-Module chassis is providing fiber to copper conversion and two copper ports for managing a control light.
The second fiber link is distributed to another iConverter 2-Module Chassis with the same configuration that is controlling equipment at a commuter station. This configuration can be continued to multiple nodes along the train route.
The final fiber link connects back to a standalone converter that provides copper connectivity to a redundant router at the network core. The resilient ring topology provides redundant link reliability in the event a fiber link is broken, the other links are fully operational, and there is no network down time.
