SFP28 Evaluation Test Board Is Suitable For 25Gbps Product Testing
Evaluate board design considerations
Compatibility: The evaluation board should be compatible with
different brands and models of 25G SFP28 optical modules to ensure
versatility and flexibility in different scenarios.
Interface standards: The evaluation board should follow standard
interfaces such as SFF-8431 and SFF-8432 to ensure proper
connection and communication with the optical module.
Performance parameters: The evaluation board should be able to
accurately measure and evaluate the key performance parameters of
the 25G SFP28 optical module, such as transmission rate,
transmission distance, power consumption, operating temperature
range, etc.
Reliability: The evaluation board should have good stability and
reliability to ensure the normal operation in a long time and harsh
environment.
Ease of use: The evaluation board should provide a friendly user
interface and convenient operation to facilitate users to test
modules and record data.

Evaluate board functional requirements
Module identification and configuration: The evaluation board
should be able to automatically identify and configure the
connected 25G SFP28 optical module, including its type, rate,
operating mode, etc.
Performance test: The evaluation board should be able to perform
performance tests on optical modules, including transmission rate
test, bit error rate test, optical power test, etc.
Monitoring and alarm: The evaluation board should be able to
monitor the working status of the optical module in real time, and
send an alarm signal when there is an anomaly, so that measures can
be taken in time.
Data recording and analysis: The evaluation board should be able to
record test data and provide data analysis capabilities to help
users better understand the performance and stability of the
optical module.
