UC9710A 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 product 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.

UC9710A CDR has a SFP optical port, which is suitable for SFP encapsulated conventional SFP, SFP+, OLT SFP and other optical modules. It only needs the receiving end of the optical module to convert the optical signal to the electrical signal, and then extract and output the clock of the electrical signal. Clock signal is mainly used for the trigger signal of oscilloscope.

UC9710A CDR全速率時鐘恢復儀有源測試設備（時鐘恢復儀）主要用于在沒有觸發時鐘的測試環境，提供時鐘恢復信號，從而利用采樣示波器測試器件的光眼圖。典型應用是光網絡設備的測試，或者針對PON應用中的BOB產品，由于被測光設備本身沒有分頻時鐘輸出，在測試光眼圖時需要恢復時鐘信號用于觸發采樣示波器。

UC9710A CDR全速率時鐘恢復儀有源測試設備帶有一個SFP光口，適用SFP封裝的常規SFP、SFP+、OLT SFP等光模塊接入，僅需要光模塊的接收端，將光信號轉換為電信號，CDR再將電信號的時鐘提取出來并輸出，時鐘信號主要用于示波器的觸發信號。
