PAM4 optical analysis option for real-time oscilloscopes
The option comprises an optical reference receiver (ORR) compliant for 28-GBaud PAM4 applications that supports IEEE/OIF-CEI standard specific measurements. This complements Tektronix’ optical PAM4 analysis tools for sampling oscilloscopes, giving design teams efficient test solutions for all stages of the optical transmitter workflow. DPO7OE1 takes the form of a calibrated optical probe and analysis software for use with real-time oscilloscopes.
Based on real-time oscilloscopes such as Tek’s DPO70000SX, this offering allows R&D and system engineers to more easily troubleshoot their optical devices by adding powerful debug capabilities: software clock recovery for PAM4 and NRZ, triggering, error detection, and capture time correlated or contiguous record of a signal.
Maxim Integrated, in its role as manufacturer of high-speed, low-power optical devices for data centre applications, is quoted; “Advanced optical modulation formats like PAM4 require system testing with both sampling and real-time oscilloscopes,” said Jan Filip director of advanced R&D at Maxim Integrated. “The new real-time oscilloscope-based solution allows us to provide critical debugging feedback to the development teams and to emulate advanced optical receiver systems using offline Matlab algorithms.”
The DPO7OE1 offers 33 GHz optical bandwidth for 28-GBaud PAM4 debug applications. It can also be used for legacy NRZ applications. Analysis packages support standard optical measurements including ER, AOP, OMA, eye height and eye width as well as PAM4 IEEE and OIF-CEI standard specific measurements including TDECQ. Pricing starts at $35,000
