SBB feasibility study confirms the suitability of HUBER+SUHNER components for railway gigabit networ
Fiber optic technology is good for creating Gigabit networks for use on trains and HUBER+SUHNER products have proven themselves' is the conclusion of an SBB trial report - a major confirmation from a field test.

A Swiss Federal Railways (SBB) one-year study has concluded that optical fiber is a suitable technology for use on rolling stock. During the trial SBB tested a variety of connectivity components for gigabit networks on trains, including fiber optic cables, connectors and databus cables from HUBER+SUHNER. All the products tested passed with excellent results.
 
With ever-increasing data usage demands due to new, complex multimedia applications, train networks in the future will require at least ten times the bandwidth than is currently being delivered. In response to this development, the SBB has installed a Gigabit Ethernet network in a railway vehicle. The network was tested over a one-year period, enabling SBB to test the technologies and products already available on the market.

Fiber optic products and databus cables for data-intensive applications
HUBER+SUHNER supplied a number of two and four-core fiber optic cables and QODC connectors for the trial, as well as its RADOX® RAILCAT Cat7 databus cables. With the help of these components the train was equipped with a test network which included 24 surveillance cameras, a passenger information system including twelve screens and six LED displays as well as an intercom system. As future video surveillance systems are likely to operate with higher video resolution, SBB assumed that bandwidth requirements would be likely to increase even more in the future. SBB also took into consideration the possible future installation of an infotainment system. This would also create greater amounts of data which would need to be handled.
 
Suitability of HUBER+SUHNER products
SBB’s report cites very positive results and confirmed  that handling the fiber connections and plug-in connectors was extremely straightforward. The cables were comparatively thin and could be installed with relatively tight bending radius. HUBER+SUHNER’s fiber optic inter-vehicle jumper cables showed no signs of damage, water leakage or moisture. The connections showed no visible signs of ageing, so that it could be assumed they would function reliably over a longer period of time. In addition SBB confirmed that the use of fiber optic technology presented no greater risk than the previously used copper cables.
 
"We are very pleased with the SBB test results," says Eric Louis-Marie, Market Manager at HUBER+SUHNER. "The deployment of fiber optic cables in railway vehicles is still being carefully observed in the railway market despite the fact that we have completed large, successful reference projects all over the world and we can therefore rely on long-term experience. The SBB's test results are further confirmation that our railway products can fulfil future requirements.” continued Louis-Marie.
 
In conclusion HUBER+SUHNER’s RADOX® backbone and inter-vehicle jumper cables, and its CAT7 databus connectors provide robust products that enable the building of reliable Gigabit networks in trains.
