About Exfo
Reviewed 2026-07-26
EXFO Inc. develops test, monitoring, and analytics systems for communications networks and optical technologies. Its instrument families cover fiber inspection, optical power and loss, OTDR and intelligent link mapping, live-fiber identification, xPON and Ethernet service testing, network synchronization, RF and 5G testing, laboratory optical characterization, and remote fiber monitoring. The manual catalog therefore belongs to a current manufacturer with both field and laboratory measurement portfolios.
History
EXFO's official material dates the company to 1985. A company account of founder Germain Lamonde says he launched the firm from a student apartment with the goal of building a leading fiber-optic test company. EXFO expanded from portable optical test instruments into modular field platforms, lab and manufacturing systems, protocol testing, software automation, network monitoring, and analytics. Current product pages span handheld optical-fiber multimeters, OTDR-based remote monitoring, component testers, tunable lasers, optical spectrum tools, and transport-network test systems.
EXFO was formerly listed on NASDAQ and the Toronto Stock Exchange. In 2021, a corporation controlled by Lamonde completed the acquisition of the remaining subordinate voting shares on August 27, 2021, returning EXFO to private ownership while explicitly retaining its Québec City headquarters. A current company ISO 9001 certificate names EXFO Inc. at 400 avenue Godin in Québec City and covers design and service of telecommunications test and measurement instruments and adaptive service-assurance systems. This draft treats the founder-controlled private company as independent rather than assigning a parent company.
