10 Gbps Full Rate CDR Adaptive Rate 2/4 Frequency Division
U9710 CDR (Clock Recovery Module ) is mainly used to provide clock recovery signal in the test environment without triggering clock, so as to use the sampling oscilloscope to test the optical eye diagram of the device. The typical application is the testing of optical network equipment or the BOB prodUt in PON application. Because the photometric device itself has no frequency division clock output, it is necessary to recover the clock signal to trigger the sampling oscilloscope when testing the optical eye diagram.
Full-rate clock recovery
Support clock signal recovery at rates of 10Gbps and below (such as 1.25Gbps, 2.5Gbps, 6.25Gbps, etc.), covering common communication standards (such as 10GBASE-R, 10G Fibre Channel, etc.). Some high-end models can be expanded to 25Gbps or higher.
Low jitter and high precision
The jitter of the restored clock is usually less than 1ps (picosecond level), ensuring the accuracy of the test results.

The 10Gbps full-rate clock recovery instrument is a key device used for high-speed communication testing. Its core function is to extract clock signals from high-speed data streams, providing a stable trigger clock for test equipment (such as sampling oscilloscopes), thereby achieving precise analysis of signal quality.
