Data rate calculations
This section provides instructions, tables and graphs to allow calculation of the data
rate capacity that can be provided by alternative PTP 300 and PTP 500 configurations.

Data rate defined
The data rate capacity of a PTP link is defined as the maximum end-to-end Ethernet
throughput (including Ethernet headers) that it can support. It is assumed that
Ethernet frames are 1500 octet. Data rate capacity is determined by the following
factors:
• Product (PTP 300 or PTP 500)
• Link Symmetry
• Link Mode Optimization (IP or TDM)
• Modulation Mode
• Channel Bandwidth
• Link Range
