THE NEXT GENERATION OF

RAILWAY COMMUNICATIONS

More than 210,000 km of railway track worldwide is equipped with GSM-R. Moving this infrastructure to FRMCS will be one of the most significant changes to railway communications in decades.

The benefit of the transition is clear. FRMCS unlocks a range of use cases and applications that will enable a new, digital railway: • Mission-critical voice communications • Digital signaling, including ETCS • Automatic Train Operation and real-time driver information • Video communications and surveillance • Smart maintenance and infrastructure monitoring • Real-time passenger information Supporting these applications will require continuous, reliable and secure connectivity across the railway. Networks will need higher capacity, lower latency, reliable high-speed connections and the resilience expected from mission-critical infrastructure. FRMCS uses 5G technology to help deliver these capabilities, but applies them within a framework developed around the specific operational and safety requirements of rail. It is a large-scale change; however, the starting point for the transition is ensuring the underlying RF and fiber infrastructure is in place to support it.

INFRASTRUCTURE

FOR EVERY RAIL ENVIRONMENT

DIFFERENT ENVIRONMENTS. DIFFERENT DEMANDS. FRMCS infrastructure must accommodate different site architectures, installation conditions and migration requirements across the railway. The right infrastructure approach depends on where it is deployed and the applications it will need to support both now and in the future. Trackside Trackside macro sites require flexible RF, FTTA and PTTA configurations that can work with existing infrastructure. Fiber is also used to carry data over long distances, linking trackside cabinets, radio sites and stations.

Stations Station infrastructure must support operational and commercial systems across complex indoor and outdoor environments. Cable selection must deliver RF and data performance while overcoming installation restrictions and meeting fire safety requirements.

Tunnels Tunnel deployments require predictable RF coverage across FRMCS frequencies, including support for MIMO where additional capacity is needed. Fiber provides the transport layer for radio, monitoring and safety systems. Cable solutions must meet strict fire-safety requirements without compromising mechanical performance. RFS addresses all of these requirements with RF and fiber solutions that can be configured to meet the needs of each railway project. 6

BOX LESS FIBER

APPLICATION

THE SOLUTION

The box less application allows a direct connection between the trunk cable and the jumpers. This reduces costs. In this case, the jumpers are directly equipped with the AOPC for the Nokia radios. However, the jumpers are also available with a FULLAXS for Ericsson radios or with a simple LC duplex. The connection between the trunk cable and the jumpers is made with an ODVA connector, which does not require the use of any additional tools. A so-called Quick Lock connector is also available, which establishes the connection by simply plugging it in and snapping it into place.

THE PRODUCTS FIBER JUMPERS The fiber jumpers are pre-assembled with the ODVA connector on one end that connects directly to the trunk cable. On the other end there is a choice of different connectors (LC Duplex, AOPC, NSN Grommet or a FULLAXS) to suit RRHs from a range of OEMs and enable a clean and fast installation. FIBER TRUNK CABLE This pre-assembled “plug-and-play” cable is terminated with multiple ODVA connectors, eliminating the need for a box on top of the roof or tower. It connects directly to the jumper, which then interfaces to the radio for an easy and quick-to-deploy installation.
