What is an EI file?

EI files mostly belong to EXFO Analyzer. EI files are used as fiber optic trace files by optical test equipment. They store data recorded during optical testing, reflecting measurements along a fiber route.

Purpose: Hold precise test data for fiber optic cables.

Functionality: Capture trace information used in diagnostics and network performance analysis.

Usage: Primarily generated by systems from EXFO, these files record the light intensity over distance along a fiber.

FilExt.com tip: The file format is proprietary; you usually need specialized software from EXFO or compatible analysis tools to open and review the data.
