The Remote Unit (TFAx) is a device which provides optical-to-electrical downlink conversion
and electrical-o-optical uplink conversion, thus allowing a bidirectional transmission of
signals between the Master Unit and the remote antennas. It is available in 3 different power
confi gurations (Low/Medium/High), housed by 4 different architectures (Case B, Case R, Case
R2 and Case F), so as to fulfi l different coverage and band requirements.
In downlink, each TFAx receives an optical signal from the Master Unit, performs an optical-to-
RF conversion, and transmits the resulting signal to the 2 antenna ports.
In uplink, it receives an RF signal from the remote antennas, provides an RF-to-optical
conversion, and conveys the converted signal to the Master Unit through optical fi bres.
The ION_B Remote Units are available both with power supply 90÷264 Vac and with power
supply -72÷-36 Vdc. Each ION-B Remote Unit is provided with a suitable external power
adapter (TPSNx: please refer to table 2.1).
Last, each ION-B Remote Unit has a wideband auxiliary channel, which can be exploited for
dedicated RF distribution.
