Chapter 1: Product description Overview of the PTP 650
Hardware overview
The main hardware components of the PTP 650 are as follows:
• Outdoor unit (ODU): The ODU is a self-contained transceiver unit that houses both radio and
networking electronics. The ODU is supplied in the following product variants:
o Integrated or Connectorized: The ODU may be either Integrated (attached to its own flat
plate antenna) or connectorized (without an antenna).
o FCC/IC, EU or RoW: These variants are for deployment in the USA and Canada, the EU and
the rest of the world respectively.
• Power supply unit (PSU): There is a choice of two PSUs:
o The AC Power Injector is suitable for installations without an auxiliary device.
o The AC+DC power injector is required when powering from a DC supply or when the PSU
is needed to operate at extreme temperatures.
• Antennas and antenna cabling: Connectorized ODUs require external antennas connected
using RF cable.
• Ethernet cabling: All configurations require a copper Ethernet Cat5e connection from the ODU
(PSU port) to the PSU. Advanced configurations may also require one or both of the following:
o A copper or optical Ethernet connection from the ODU (SFP port) to network terminating
equipment or another device.
o A copper Ethernet Cat5e connection from the ODU (Aux port) to an auxiliary device.
• Lightning protection unit (LPU): LPUs are installed in the PSU and Aux copper drop cables to
provide transient voltage surge suppression.
• Ground cables: ODU, LPUs and outdoor copper Ethernet cables are bonded to the site
grounding system using ground cables.
