3. Module key parameters test

The performance indexes of INTEL E25GSFP28SR sample module on the test board are tested under the condition of 45℃ in the laboratory module shell, and the test results are as follows;

Table 3 INTEL E25GSFP28SR Performance Indicators

	Transmit optical power	Power consumption	Receive sensitivity (over fiber)	Receive sensitivity (over 100 m fiber)	Remarks
10G	-2.225dBm	0.549W	-14.778dBm	-14.508 dBm	0 BER
25G	-2.456dBm	0.552W	-12.845dBm	-12.492dBm	5E-5 BER

The sample module enclosure was tested at 45°C optical eye diagram with the following eye diagram template and parameters:
