The perfect pairing for Ethernet networks in railway technology.

Today, passenger information systems that transmit audio and video signals represent standard equipment on most trains and increasing numbers of travellers are expecting to find high-end infotainment systems with internet access. All of this presents rail operators with the need to increase transmission capacity and adapt existing rolling stock to the changes in user requirements.

Transmission of high-speed signal and data is a key challenge on new state-of-the-art trains as well as upgrading existing rolling stock. Users have turned to Ethernet technology to deliver viable solutions, using a central Ethernet ‘backbone’ that supports structured networks throughout the entire length of the train. The Ethernet backbone links equipment such as CCTV cameras, Wi-Fi networks and passenger information systems.

Inter-car connections in such systems are achieved using jumper cables and robust connectors which provide sufficient bandwidth to allow future expansion to accommodate these developments. Using HARTING Han® Modular connectors with ground disconnect, these solutions provide full 10 Gigabit transmission tested to IEEE 802.3 utilising CAT 7 cables. They are compliant with fire regulation EN 45545 – 1, 2 & 5 and EN 50155:2007 to ensure reliable application on rolling stock, and offer industry-leading IP68 and IP69K sealing capability. HARTING connectors also carry IRIS certification to meet the stringent demands of the rail industry.

This improved inter-car connection allows for faster and more reliable on-board connectivity, improving the customer experience.Supporting CAT 5, 6 and 7Ea, this offering from HARTING allows train operators to future proof rolling stock.

Latest product developments for the rail industry from HARTING include preLink®, for fast onsite termination. The preLink® installation system together with Ha-VIS EtherRail® cables specially configured for railway requirements allow these future-orientated data networks to be quickly and reliably installed. The fundamental idea behind the preLink ® technology is the separation of the cable connection and the mating face. At its core is a cable termination block in which the stranded wires are inserted separately. The assembly process is completed with pliers that ensure reliable results onsite.

The small size of the contact block means that the data cables can be prepared ready for use outside of the car and then installed reducing installation time and error rate. The Ha-VIS preLink® terminal block can then be fitted to any of the various Ha-VIS preLink® mating faces for example M12, RJ45 and PullPush. Particularly given the long periods of use in railway technology, these products offer a high level of flexibility and a safe investment.

HARTING continuously develops products specifically for the rail industry, designed to withstand the ongoing shock and vibration in tough environments. From heavy duty connectors, electrical connectors, industrial grade Ethernet switches and cable assemblies to the highest quality standards to allow for fast, secure connections throughout the train.
