2.6 Applications
The ITS
Blade
is designed specifically for harsh temperature environments and brings
future-proof fiber and widely used copper connectivity to out-of-the-way sites and outdoors.
Example 1. Magnum ITS Blade
In this example, a Magnum ITS
Blade
Hardened Switch
serves real time roadside traffic data collection and transmits it to a remote control station over
fiber. Since multiple traffic control sites here are a long distance apart, they are all connected in
series to each other and to the central station or TOC.
Some local users (using RJ-45 ports) may operate at 100Mbps, and some users and
utility devices may run at 10 Mbps. A Magnum ITS
Blade
Hardened Switch serves this
requirement economically and efficiently. The six full- and half-duplex switched ports make the
required setup simple for collection of traffic data, including streaming video from one or more
cameras. The advanced thermal techniques enable operation in un-controlled outdoor
temperatures, and provide high reliability of the ITS
Blade,
make it suited to the roadside site.
The two 100Mbps full-duplex fiber ports fulfill the long distance connection need, and provide

and100Mbps network devices, providing a 100Mb Ethernet fiber
backbone
for access to the central control station (TOC)
