EXFO ACQUIRES AVANTAS NETWORKS, A LEADING-EDGE PROTOCOL LAYER TESTING COMPANY

COMBINED COMPANY BECOMES A LEADING GLOBAL SUPPLIER OF FIBER-OPTIC PHYSICAL AND
PROTOCOL LAYER TESTING EQUIPMENT

QUEBEC CITY, CANADA, August 23, 2001--EXFO Electro-Optical Engineering Inc.
(NASDAQ: EXFO, TSE: EXF) announced today it has entered into an agreement to
acquire Avantas Networks Corporation for approximately US$65 million, or US$93
million for the equity minus US$28 million of Avantas cash on hand.
Consideration paid consists of approximately 4.4 million EXFO shares and US$36
million in cash.

Avantas, a Montreal-based, pre-revenue company that recently released datacom
and telecom testers capable of measuring up to 10 Gb/s systems, is a supplier of
leading-edge fiber-optic testing and optical network performance management
equipment that supports a wide range of protocols and data transmission rates.

Based on the latest ASIC and FPGA technologies, its portable Service Test Gear
(STG) Series products represent the only solution that supports multi-protocols
like ATM, SONET, SDH, Gigabit Ethernet and Ethernet, as well as data
transmission rates from OC-192 (10 Gb/s) down to DS0 (64 kb/s) in North America
and STM-64 (10 Gb/s) down to E0 (64 kb/s) in Europe and abroad, on a single
platform. These feature-rich-instruments, with one of the smallest footprints in
the industry, test critical network performance parameters.

Avantas' remote optical network performance management system, Network Guardian
G2, provides real-time surveillance 24 hours per day, seven days per week. A
single administrator can simultaneously observe critical Quality of Service
(QoS) parameters at key locations in the network by relying on data from remote
Network Guardians. This system is fully complementary to EXFO's remote fiber
test system.

Similar to EXFO's product portfolio, these product lines are designed for
telecommunications carriers, system manufacturers and research labs.

"This strategic acquisition enables us to leverage our 16-year leadership in
physical layer testing and address the new protocol layer testing requirements
emerging with advanced DWDM networks," said Germain Lamonde, Chairman, President
and CEO of EXFO. "We will now be able to offer our customers a one-stop solution
for all of their fiber-optic testing needs. In fact, we plan to integrate both
physical and protocol layer technologies inside our FTB-400 Universal Test
System and IQ platform.

"Bridging the two technologies inside one box is something the market has been
anxiously awaiting for quite some time."

This transaction enables EXFO to enter the lucrative fiber-optic protocol layer
testing sector and significantly increase its addressable market size. The
global fiber-optic protocol layer test equipment market is expected to increase
from US$1.6 billion in 2001 to US$3.1 billion in 2005, according to a May 2001
global market study on ATM, SONET and SDH test equipment from Frost and
Sullivan, a leading high-tech market research firm.

"It's a terrific match between Avantas and EXFO," said Sami Yazdi, Chairman,
President and CEO of Avantas. "We are bringing state-of-the-art technology and a
leading-edge development team on the protocol layer testing side, while they're
delivering strong brand name recognition and a global sales channel.

"It's also an ideal fit in terms of culture, product development and management
to become industry leaders in our space."

EXFO plans to take advantage of Avantas' strong research and development
team--60 out of approximately 100 employees are engineers with experience at
companies like Nortel Networks, Marconi and Cisco--to quickly gain market share
in the protocol layer testing market.

The Avantas acquisition has been approved by the board of directors of both
companies, but it is subject to regulatory approval and other customary closing
conditions. The deal is expected to close by the end of the first quarter of
fiscal 2002. The transaction will be accounted for under purchase accounting.
