Applied Optoelectronics, Inc. (AAOI) vs Analog Devices, Inc. (ADI)
The same free fields, in the same order, for both companies, so a figure on one line can be read straight across.
This page states measurements and nothing else. It does not rank the two companies, name one of them, or draw a conclusion from the figures.
Data as of Oct 27, 2026, for both companies.
The figures, field by field
A dash means the snapshot carries no figure for that company on that line. A line is dropped only when neither company has it, so a dash beside a figure is a fact about coverage, not about either company.
