TRACK TECHNOLOGY
Readers of recent issues of RTM will know of HUBER+SUHNER’s rolling stock connectivity expertise. Here, the company highlights how its technology improves trackside communications and electrical performance.
T
oday’s rail industry is tasked with the role of providing safety, reliability,
the effi cient use of energy and, of course, passenger comfort and enjoyment.
To make this happen, a wide variety of technologies are used together, which need to be connected and transmitted. It is here that HUBER+SUHNER’s connectivity solutions fi nd wide application.
The company’s three key technologies of radio frequency, low frequency and fi bre optics are used globally in rolling stock and trackside applications to provide control, signal and power cables, connections for railway information products as well as solutions for wireless communication systems.
Here are just some of the areas where HUBER+SUHNER offers products designed specifi cally for trackside applications:
• Control and power cables and cable systems;
• Antennas for trackside communications; • RF connectors and assemblies; • Fire resistant cables; • Control cabinets and control panel solutions;
• Circuit and lightning protection devices; • Fibre optic solutions for signalling installations;
• Fibre management systems; • Wireless and wired communications systems.
Wireless Ethernet The company’s established SENCITY®
York City Subway at 86th Street/Lexington Avenue. Passing trains and electromagnetic pulses had no effect on the link, which was crossing the tracks. Even the limited space available for the required line of sight did not infl uence the link quality.
RF cables and cable assemblies
HUBER+SUHNER is a recognised leader in the supply of RF coaxial cables and cable assemblies for trackside applications. The company offers an excellent range of low smoke, halogen-free cables for frequencies up to 8GHz, which covers most railway requirements including GPS, WiFi, WiMax, GSMR, 3G and general signalling.
As well as cable, the company produces a comprehensive range of RF connectors in both traditional interfaces such as N type, SMA and BNC as well as the newer ‘Quick Lock’ styles such as QN and QMA. Both cable and connectors can be brought together at HUBER+SUHNER’s cable assembly facility.
These can be produced in kits or integrated into higher level assemblies such as chassis or front panels together with third party hardware.
Fibre optic cables Link
SL60 wireless Ethernet bridge technology has come to the UK following the recent announcement by the regulator Ofcom that it has made the 60GHz band available licence-free for fi xed wireless links. Already extensively used around the world in railway applications, SENCITY LINK 60 has recently been successfully tested in the New
SENCITY LINK operates as a point-to-point wireless Ethernet bridge and the company has made available three product variants offering speeds from 100Mbps to 320Mbps Full Duplex at distances of between 600m and 1.6Km. The SL60-401 Gigabit Ethernet bridge, for example, features a transmission capacity of 320Mbps Full Duplex and a range of up to 800m. It measures just 182 x 182 x 71mm, weighs 2,500g and is very easy to install. Because of the oxygen absorption level at 60GHz, the SL60’s immunity to interference allows many links to be deployed in the same area.
HUBER+SUHNER has established a special website for its SENCITY LINK SL60 technology and products –
www.sl60.com – and readers are invited to visit this site for more information.
The company’s latest multi-fi bre loose tube fi bre optic cable is designed for systems and equipment that need fast data transmission rates including signalling,
platform
information systems, video links and CCTV as well as ticketing systems.
Available with fi bre counts from 24 up to 144 fi bres, it is suitable for both inside and outdoor use and is low smoke, halogen free and self-extinguishing – characteristics that should allow the cable to meet exacting fi re safety standards including London Underground’s 1-085 Fire Safety Performance of Materials Specifi cation.
In addition to the cable, HUBER+SUHNER is able to offer fully terminated and tested fi bre optic assemblies.
