FAQ
How is the Passive Optical Components company list decided?
Every company comes from a product disclosure in its own annual report — the right-hand column quotes the original filing verbatim, with the fiscal year. Nothing is added from industry lists, analyst reports or news: a company that everyone "knows" makes this will still be absent if its filings never say so.
Is this list complete?
No guarantee of completeness. Coverage is limited to the filings this site has collected and extracted, and disclosure wording varies by company — only sufficiently specific language gets placed. Every listed company has a source; an absent one may simply not be covered yet.
