Outdoor unit (ODU)
This section describes the PTP 800 ODU and its interfaces.
ODU description
The PTP 800 outdoor unit (ODU) provides the necessary frequency conversion and
amplification of signals which pass between the CMU and antenna.
In the transmit direction, the ODU takes the fixed intermediate frequency (IF) signal
provided by the CMU and converts and amplifies it to a configured licensed band radio
frequency signal for transmission at the antenna. In the receive direction, the ODU
provides amplification and down conversion of a licensed band signal received at the
antenna interface. The result is a fixed IF signal which is passed to the CMU for
demodulation.
ODUs are available in all licensed bands supported by PTP 800 (see
on page
for the full list of supported bands). A given licensed band is
generally split into sub-bands where a given sub-band is supported by a pair of ODUs. One
ODU is designed to transmit at the high frequency side of the Frequency Division Duplex
(FDD), the other at the low frequency side. The ODU transmit and receive frequencies are
configurable within a sub-band.
The ODU is designed for outdoor operation, either mounting directly to the back of an
antenna or mounted separately using a Remote Mount Kit which then connects to the
antenna with flexible waveguide.
The ODU also provides an interface which allows the installer to monitor the receive signal
level when aligning antennas.
Alternative ODU platforms
There are two alternative ODU platforms: ODU-A and ODU-B. The platform can be
identified from the label.
ODU-A is available in all bands, whereas ODU-B is only available in selected regions and
bands. ODU-B is the preferred choice when available, as it offers the following advantages
over ODU-A: higher transmit power and lower power dissipation.
Do not install an ODU-A and an ODU-B in the same link.
For more information about the capabilities and availability of ODU-A and ODU-B, refer to
