12 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 configurations.
The following topics are described in this section:
•
12.1 Data Rate Defined
•
12.2 Calculation Procedure and Example
•
12.3 Data Throughput Capacity
•
12.4 Range Adjustment Curves
12.1 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:
•
Link Symmetry
•
Link Mode Optimization (IP or TDM)
•
Modulation Mode
•
Channel Bandwidth
•
Link Range
12.2 Calculation Procedure and Example
12.2.1 Procedure
To calculate the data rate capacity of a PTP 300 link, follow this procedure:
1. Use the tables in Section 12.3 to look up the data throughput capacity rates (Tx, Rx
and Both) for the required combination of:
o
Link Symmetry
o
Link Mode Optimization
o
Modulation Mode
o
Channel Bandwidth
