The Optical to Electrical (OE) converter (the manufacturer calls it a photo receiver) is very useful in many applications when checking laser light sources or outputs of data links in fiber optic systems. We have tested a 12GHz model 1554-B from the New Focus company (http://www.newfocus.com/com/) with the LeCroy SDA Zi series oscilloscopes. Using the New Focus 1554-B Photo Receiver with a LAB BRIEF WM-453 LeCroy Oscilloscope January, 2010 Introduction This receiver’s clean responses and 35-ps rise times make the product Summary well-suited for a time-domain characterization of 10-Gbit/s signals. Using the scope's built in parametric measurements and math functions we are The Optical to Electrical (OE) able to perform the dark calibration and measure extinction ratio. converter (the manufacturer calls it a photo receiver) is very useful in many Set-Up applications when checking ……
