User Guide: PTP 600 Series Data rate calculations

Data rate calculations

The following topics are described in this section:

• Data rate defined on

• Range adjustment curves on pag

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 variant (PTP 600 Full or Lite)

• Link Symmetry

• Link Mode Optimization (IP or TDM)

• Modulation Mode

• Channel Bandwidth

• Link Range

Procedure

To calculate the data rate capacity of a PTP 600 link, perform Procedure 4-1.

Procedure 4-1 Calculating data rate capacity

Use the tables in data throughput capacity rates (Tx, Rx and Both) for the required combination of:

The tables contain data rates for PTP 600 Full only. If the ODUs are PTP 600 Lite, divide the data rates by 2.

The tables contain data rates for links of zero range. Use the curves in

Multiply the data rates by the Throughput Factor to give the throughput capacity of the link.

NOTE

There is a small difference between the rates for IP and TDM because there is fragmentation in TDM (for low priority traffic) which causes the throughput to be reduced buy approximately 1% compared to the IP mode.

Example

Suppose that the link characteristics are:

• Product variant = PTP 600 Lite

• Link Symmetry = 1:1

• Link Mode Optimization = TDM

• Modulation Mode = 64QAM 0.92 Dual

• Channel Bandwidth = 10 MHz

• Link Range = 60 km

Use

• Tx = 41.41 Mbits/s

• Rx = 41.41 Mbits/s

• Both = 82.81 Mbits/s

Divide these rates by 2 to give PTP 600 Lite rates:

• Tx = 20.70 Mbits/s

• Rx = 20.70 Mbits/s

• Both = 41.40 Mbits/s

Use Range 60 km. The factor is 0.86.

Multiply the rates from Step 2 by the Throughput Factor from Step 3 to give the throughput capacity of the link:

• Rx = 17.80 Mbits/s

• Both = 35.60 Mbits/s
