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全速率時鍾恢複儀(yi) 有源測試設備（時鍾恢複儀(yi) ）主要用於(yu) 在沒有觸發時鍾的測試環境，提供時鍾恢複信號，從(cong) 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(chan) 品，由於(yu) 被測光設備本身沒有分頻時鍾輸出，在測試光眼圖時需要恢複時鍾信號用於(yu) 觸發采樣示波器。

UC9710A CDR全速率時鍾恢複儀(yi) 有源測試設備帶有一個(ge) SFP光口，適用SFP封裝的常規SFP、SFP+、OLT SFP等光模塊接入，僅(jin) 需要光模塊的接收端，將光信號轉換為(wei) 電信號，CDR再將電信號的時鍾提取出來並輸出，時鍾信號主要用於(yu) 示波器的觸發信號。
