Parameters Specified for Interfaces

Table 1 lists the parameters specified for the electrical interfaces of the EFT4.

Ethernet Performance Specifications

Figure 1 shows the connection for testing the throughput specifications, packet loss ratio in the case of overloading, and latency specifications of the EFT4.

Figure 2 shows the connection for testing the back-to-back specifications of the EFT4.

Table 2 lists the throughput specifications of the EFT4. Table 3 lists the packet loss ratio in the case of overloading of the EFT4. Table 4 lists the latency specifications of the EFT4. Table 5 lists the back-to-back specifications of the EFT4.

Table 2 lists the throughput specifications of the EFT4. The values are obtained when the SmartApplication is set as follows:

• The specifications in the table are obtained in the scenario wherein point-to-point transparent transmission services are configured and the flow control function is disabled.
• The permitted packet loss ratio is set to 0% and the resolution rate is set to 0.1%.
• The test duration is set to 60 seconds.

Table 3 lists the packet loss ratio in the case of overloading of the EFT4. The values are obtained when the SmartApplication is set as follows:

• The specifications in the table are obtained in the scenario wherein point-to-point transparent transmission services are configured and the flow control function is disabled.
• The tested traffic starts from the throughput and increases to 100% in 10% steps.
• The test duration is set to 60 seconds.

Table 4 lists the latency specifications of the EFT4. The values are obtained when the SmartApplication is set as follows:

• The specifications in the table are obtained in the scenario wherein point-to-point transparent transmission services are configured and the flow control function is disabled.
• The test duration is set to 60 seconds.
• The latency modes are classified into two modes, namely, cut through mode and store forward mode. In cut through mode, the analyzer calculates the difference between the time when the first bit of the transmitted frame reaches the output port of the tested equipment and the time when the first bit of the transmitted frame reaches the input port of the tested equipment. In store forward mode, the analyzer calculates the difference between the time when the first bit of the transmitted frame reaches the output port of the tested equipment and the time when the last bit of the transmitted frame reaches the input port of the tested equipment. In the table, the CT values are obtained in cut through mode and the S&F values are obtained in store forward mode.

Table 5 lists the back-to-back specifications of the EFT4. The values are obtained when the SmartApplication is set as follows:

• The specifications in the table are obtained in the scenario wherein point-to-point transparent transmission services are configured and the flow control function is disabled.
• The frame size is set to the range from 64 bytes to 1518 bytes, the packet transmission rate is set to 100%, the test duration is set to 2 seconds, and the number of repetitions is set to a value more than 50 on the Smart Application.
• The tested traffic is set to the wire speed.
• The test duration is set to 10 seconds.

• Dimensions (mm): 25.4 (W) x 235.2 (D) x 128 (H)
• Weight (kg): 0.5

Power Consumption

The maximum power consumption of the EFT4 at room temperature (25°C) is 14 W.
