Westermo ODW-Series Serial to Fibre Modems validated for MicroLok® Interlocking Applications
The Westermo ODW-Series Serial to Fibre Modems have been successfully validated for use with the Ansaldo-STS MicroLok® II Solid State Interlocking System. Recent compatibility testing at Ansaldo’s Newcastle test facilities successfully validated communication between two MicroLok® II Controllers using both MicroLok® P2P (Peer-to-Peer) and Master-Slave communications protocols.
Ansaldo-STS MicroLok® II controllers are used extensively in the Rail Industry to provide multi-purpose monitoring and control for rail and transit wayside interlocking equipment. Its wide range of functional capabilities include vital interlocking control, non-vital code system applications, train detection, rail integrity, coded track circuit communication and more.
Westermo ODW-Series Serial to Fibre Modems offer a track-side certified industrial grade solution for long-haul serial communications between MicroLok® controllers over fibre optic cables. The flexibility of the ODW-Series provides support for Multi-mode and Single-mode fibre connectivity and flexible topologies such as Point-to-Point, Multi-drop and Redundant Ring. RS-232; RS-422 and RS-485 serial interfaces are all supported.
By incorporating an SFP port to accommodate different Fibre Transceivers, the ODW-Series platform is extremely flexible. Should a fibre transceiver become damaged in service, it can be quickly and simply replaced with another, eliminating the need to replace the complete device.
Another significant advantage of SFP ports is the option to use BIDI transceivers which allow full-duplex communications over a single fibre core (instead of using two fibres). This effectively doubles the capacity of the existing fibre network by freeing up fibre for other uses.
