2.1 FLEXWAVE PRISM FAMILY OVERVIEW
The ADC FlexWave Prism family of products is a Distributed Antenna System (DAS)
that provides ADC’s patented technology—bidirectional transport of digitized RF
spectrum over fiber. The high-speed digitalization of a wideband portion of spectrum
allows for transport of RF signals over extended distances, without the RF
degradation that normally results when analog systems are impacted by optical
effects. The basic function of the FlexWave Prism platform is to transport via fiber
optic cable RF signals from a Base Transceiver Station (BTS) to an antenna interface
allowing communication to a mobile device. Multiple BTS communication paths are
allowed over a single Prism system. Each link consists of a Host that provides the
interface between the base station RF ports and the optical fiber, and at least one
Remote that provides the interface between the optical fiber and the remote antenna.
A block diagram of the system is shown in Figure 2-1.
