15Gbps Full Rate CDR High-speed Communication Test Equipment
The 15Gbps full-rate clock recovery instrument is a key testing
device used in high-speed communication systems (such as optical
communication, data center interconnection, etc.). Its core
function is to extract clock signals from high-speed data streams
to ensure that the receiving end can correctly decode the data.
U9710C CDR with an FC optical interface adapter, which is suitable for SFP encapsulated conventional SFP, SFP+,
OLT SFP and other optical modules. The FC optical interface to receive optical signals into electrical
signals, and then extract and output the clock of the electrical signal. The
clock signal is mainly used for the trigger signal of oscilloscope.

Typical application scenarios
Research and development and production of optical modules
In the test of 10G/25G optical modules, the clock recovery
instrument is used to extract the clock signal at the transmitting
end to verify the eye pattern quality, jitter performance and bit
error rate of the module.
It is used in conjunction with a sampling oscilloscope (such as
Tektronix DSA8300) or a bit error rate tester (such as Anritsu
MP1900A).
High-speed link testing
In data centers or 5G base stations, it is used to test the signal
integrity of high-speed backplanes, cables or connectors.
By restoring the clock signal, the insertion loss, return loss and
crosstalk in the link are analyzed.
Protocol conformance test
Verify whether the device complies with the clock recovery
requirements in the IEEE 802.3ba (40G/100G Ethernet) or ITU-T G.709
(OTN) standards.
