User's Manual Part 1

Chapter 3: System planning
This chapter provides information to help the user to plan a PTP 650 link.
The following topics are described in this chapter:
• Typical deployment on page 3-2 contains diagrams illustrating typical PTP 650 site
deployments.
• Site planning on page 3-8 describes factors to be considered when planning the proposed link
end sites, including grounding, lightning protection and equipment location.
• Radio spectrum planning on page 3-16 describes how to plan PTP 650 links to conform to the
regulatory restrictions that apply in the country of operation.
• Link planning on page 3-21 describes factors to be taken into account when planning links,
such as range, path loss and throughput.
• Planning for connectorized units on page 3-25 describes factors to be taken into account when
planning to use connectorized ODUs with external antennas in PTP 650 links.
• Data network planning on page 3-27 describes factors to be considered when planning PTP 650
data networks.
• Network management planning on page 3-31 describes how to plan for PTP 650 links to be
managed remotely using SNMP.
• Security planning on page 3-33 describes how to plan for PTP 650 links to operate in secure
mode.
• System threshold, output power and link loss on page 3-41 contains tables that specify the
system threshold (dBm), output power (dBm) and maximum link loss (dB) per channel
bandwidth and modulation mode.
• Data throughput capacity tables on page 3-49 contains tables and graphs to support
calculation of the data rate capacity that can be provided by PTP 650 configurations.
