- Railway signalling systems based on the Solid State Interlocking (SSI) system developed by British Rail
- SSI Optical Data Link Module (ODLM) over fiber or copper
FEATURES AND BENEFITS
- Replaces the standard SSI Data Link Module (DLM) with a physically compatible unit that transmits the SSI signal over optical fibers as well as over copper
- Standard unit comes with dual Datalink interface so that it can simultaneously operate with two copper trackside datalinks and a fiber bus
- Available in a SSI + fiber only version for SSI networks where trackside datalink connectivity is not required
- Completely compatible with all SSI system elements such as TCPs, TFMs, etc
- Compatible with both multimode and singlemode fiber
- Extends module separation to several kilometres of multimode fiber and to over thirty kilometres of singlemode fiber. Distances of at least 100km are possible with optional optical devices
- Two fibers in each direction is standard but single fiber operation is optional
- Provides immunity to extreme electrical interference and complete end-to-end isolation
- Up to 63 units can be placed in a bus topology
- Link Alarm Output to monitor the optical or copper links
- Extremely robust electronics and packaging designed for the severe environments typical of railway applications
