Major Finnish Operator, DNA Ltd, Selects EXFO's BrixHawk SA

QUEBEC CITY, Canada, Sept. 14, 2011 (GLOBE NEWSWIRE) -- EXFO Inc.
(Nasdaq:EXFO) (TSX:EXF) announced today that DNA has placed an order
with EXFO for the BrixHawk SA Service Assurance Solution to expand its
3G monitoring, analytics and reporting capabilities to include 4G LTE
for voice and roaming services with focus on operational efficiency
that translates into significant OPEX savings.

In 2010, DNA selected EXFO's BrixHawk SA, formerly known under the name
BrixMobile, to monitor its IP-based, circuit-switched 2G/3G mobile
network. Due to its satisfaction with EXFO's products and services, and
as it grows its network to 4G LTE, DNA wants to continue using EXFO
Service Assurance products to expand 3G reporting capabilities and
monitor 4G LTE. The scalable and flexible architecture of BrixHawk SA
was the crucial factor in DNA's choice of a service assurance solution.

"BrixHawk SA has helped us facilitate monitoring and
troubleshooting--significantly reducing the time it takes to identify
problems in the network," said Toni Nevalainen, System Specialist at
DNA. "In addition to expanding our reporting capabilities, BrixHawk SA
improves overall quality of our networks by offering flexible
architecture to extend the system without operational downtimes,
requiring no training sessions for network monitoring--whether for our
public-switched transport network (PSTN) or 4G LTE network."

"We are delighted that DNA Ltd chose EXFO for the flexible and scalable
nature of our BrixHawk SA service assurance solution," said Vivian
Hudson, Vice-President of EXFO's Service Assurance Division. "DNA's
customer loyalty is evidence of EXFO positioning itself as a leading
provider of next-generation test and service assurance solutions that
enhance and optimize the performance of 2G/3G/4G networks and services,
and we look forward to providing a significant competitive advantage as
this operator extends its service offering."
