Tektronix, Inc. unveiled two new optical modules for its DSA8300 sampling oscilloscope, providing what it asserts is the industry's highest sensitivity and lowest noise. The optical modules enable manufacturers to increase production capacity and enhance yields for 400G designs moving into production.
Tektronix also announced a software package optimized for 4 channel parallel processing for high throughput manufacturing test to deliver upgraded support for the new 400G PAM4 TDECQ measurements.
The optical industry is accelerating toward 400G and PAM4 to keep up with growing bandwidth demand in data centers, while lower signal to noise ratio, decreased signal amplitude, and an increase of over 10 times the number of tests is challenging production engineers to keep per device test cost low. Tektronix attests that its DSA8300-based sampling can contribute to these lower test costs with the industry's highest bandwidth, highest sensitivity, and with shortened test times.
According to Tektronix, the new 80C20 and 80C21 optical modules for 56 GBaud PAM4 and NRZ can be installed in DSA8300 sampling oscilloscopes, with 9 µW optical noise. With the two-channel 80C21, optical manufacturing test engineers can double throughput and capacity.
Tektronix offers a comprehensive set of enhanced PAM4 analysis tools to decompose signal content for noise and jitter, enabling engineers to understand underlying problems in the event of device failure.
"As 400G designs move into production, our customers are looking for ways to improve manufacturing yield and cost of test, which all starts with confidence in test results and the ability to quickly and accurately separate good components from bad ones," said Sarah Boen, Tektronix general manager, performance oscilloscopes. "With the industry's lowest noise and highest sensitivity, our solution delivers insights that improve yields and throughput on optical components and interconnects."
Tektronix unveiled enhancements for the DSA8300 digital sampling oscilloscope when it announced that its OM4000 series optical modulation analyzer could drive the DSA8300 to perform analysis on complex modulation formats in 2012 (see “Tektronix enhances optical modulation analysis with digital oscilloscopes").
The 80C20 and 80C21 optical modules and 400G test software upgrades will be available starting in April.
