EXFO was founded in 1985 in Quebec City by Germain Lamonde and Robert Tremblay. Its original products were portable testing products for optical networks. In 1996, EXFO started designing products for optical component and optical system research and development and manufacturing. The company has since added 3G, LTE, protocol, copper/xDSL, IMS, and VoIP test and service assurance products, mainly through acquisitions.^{[citation needed]}

In a going-private transaction, Germain Lamonde purchased all outstanding stock in the company in 2021 so that it was delisted from the TSX and NASDAQ.^[1]
