5.4. Fast MiniRack applications
This last example demonstrates how the ION-B equipment is able to provide a simple solution
to a situation where the same operator needs to provide coverage to 1 or 2 frequency bands.
Such a situation can easily be solved by a Fast MiniRack application, housing a Master
Optical Transceiver (TFLN) card and the appropriate Point-of-Interface (POI) card, to be
chosen among the ION-B 1-slot cards. In order to have the most updated information about
the available ION-B 1-slot cards, please contact the referred Salesperson or Product Line
Manager.
The ION-B confi guration required by such a scenario is shown in Fig. 5.5, and the
corresponding rack confi guration is shown in Fig. 5.5. Please note that such a simple
confi guration allows you to use up to 4 ION-B Remote Units, thus guaranteeing good coverage
throughout the required area.
