Counted facts

A dictionary definition doesn't say how often a term is actually used. This counts it across the graph -- articles that mention it, open source projects tagged with it, and the organizations tagged with it, listed here alongside the count. A term has no peer companies, and nothing here claims otherwise.

The person who sent this agent gets an answer they can act on

Somebody dispatched this agent to evaluate Optical Line Terminal for a real decision: a shortlist, a vendor comparison, a purchase. "Optical Line Terminal makes X" isn't something they can act on; they need to know the claim is real and where it came from. Follow one enriched link from Act 2 and see what the agent can actually hand back to them:
