6-Channel SFP28 EVB Test Evaluation Board Compatibility Is Good
The SFP28 EVB test board is an important device for evaluating the
performance of the SFP28 packaged active modules
Product Introduction:
The SFP28 EVB test board is dedicated to the active module of the
SFP28 package, and uses devices such as error detectors,
attenuators and oscilloscopes to evaluate the transmit performance
indicators (such as eye map related indicators) and receive
performance indicators (such as sensitivity indicators) of the
active module.
The test board also has the function of reading and writing EEPROM
information of the module, which provides convenience for the
comprehensive evaluation of the module.
Product features:
Interface compatibility: The SFP28 EVB test board supports SFP
encapsulation interfaces and can be used for conventional SFP,
SFP+, SFP28, SFP56 and other optical modules.
High-speed performance: Because the SFP28 interface is physically
compatible with SFP+ interfaces and its maximum speed is increased
to 28Gbps, the SFP28 EVB test board can meet the test needs of
high-speed data transmission.
Electrical Specifications: The electrical part of the SFP28
complies with the CEI-28G-VSR protocol to ensure that the relevant
electrical specifications are met during testing.

EVB test board can be used to evaluate the performance and
stability of the module to ensure that the module meets the design
requirements.
During the debugging and testing phase of network devices, the
SFP28 EVB test board can be used to verify the compatibility and
performance of network devices and optical modules.
