Variations in 10 Gigabit Ethernet Laser Transmitter Testing Using Reference Receivers

One of the key tools used by telecom/datacom original equipment manufacturers, system installers and system servicers to view eye patterns on an oscilloscope and test the quality of a laser’s time-domain signal is the reference receiver (RR). This application note will target two different types of time-domain optical sampling systems with reference receiver filtering from Tektronix, and through a series of measurement examples, show how and when they are used in 10GbE laser transmitter testing, as well as discuss the measurement results achieved.
