10Gbps adaptive rate full-rate clock recovery CDR 2/4 frequency
division
The U9710A/B 10Gbps adaptive rate full-rate clock recovery
instrument is a testing device that can automatically adapt the
input signal rate within the range of 10Gbps and below, and recover
a clock signal synchronized with the signal to be tested.
Adaptive rate
It supports a rate range of 1.25Gbps to 10.3125Gbps and can
automatically adapt to the rate of the input signal without manual
configuration.
Full-rate clock recovery
It can restore the full-rate clock signal synchronized with the
signal to be tested, providing a stable trigger clock for the test
equipment.

Application scenarios
Optical network equipment testing
In the testing of optical network equipment, such as ONT testing or
line board card testing, when the signal to be tested only has an
optical signal output but no clock output, a clock recovery
instrument can be used to recover the clock signal, which is then
used to trigger the sampling oscilloscope for eye diagram testing.
High-speed communication module test
It is used for testing parameters such as the emission eye diagram
and jitter tolerance limit of 10Gbps optical modules (such as XFP,
SFP+).
Research and development of data centers and network equipment
During the research and development process of data centers and
network equipment, the 10G interface performance of the equipment
is verified to ensure its reliability in high-speed data
transmission.
