An OTDR finds breaks, splices, and macrobends. It tells you nothing about the cause of 80% of optical link failures: contaminated connectors. Here's what actual fiber testing looks like — and how an SFP-based microOTDR changes the economics.

Lab validation confirms that a configuration can work under ideal conditions. It does not guarantee that it will behave the same way in production. Understanding that limitation is critical.
