New impairment identification tool gives supertechs unique insight into
network faults.

QUEBEC CITY, Jan. 16, 2013 /PRNewswire/ - EXFO Inc. (NASDAQ: EXFO) (TSX:  EXF) 
today unveiled  a new  tool  called WDM  Investigator, which  enables  network 
operators to significantly decrease  troubleshooting time and drastically  cut 
operational expenses  by  providing  unique  identification  of  DWDM  network 
impairments. Offered  as  an  option  on  the  FTB-5240S/BP  Optical  Spectrum 
Analyzers (OSA), the WDM Investigator provides users with better assessment of
impairments  affecting  DWDM  networks  on  a  per-channel  basis  for   rapid 
identification of the defective component.

Operators are  always looking  to reduce  their OPEX  and acquire  intelligent 
tools  that  speed  up  repair  time.  However,  DWDM  networks  are  becoming 
increasingly complex due to the new technologies being deployed (e.g., tighter
channel spacing, ROADMs and  polarization-multiplexed signals), which in  turn 
increases the number of  potential causes for  failure. While past  impairment 
types  were  relatively  few  and  well  known  (e.g.,  excessive  loss,  high 
dispersion and excessive ASE noise), the newly deployed technologies give rise
to previously uncommon impairments, such as crosstalk and non-linear  effects. 
Service providers have been looking for ways to identify these impairments and
their impact on signal degradation in order to troubleshoot DWDM networks more
quickly and effectively.

The  new   WDM  Investigator   featured   on  EXFO's   FTB-5240S/BP   provides 
never-before-seen    insight    into    link    characteristics     (including 
polarization-multiplexed signals and carved noise) and signal impairments, and
also provides an assessment  of their severity.  Examples of such  impairments 
include PMD depolarization, crosstalk, non-linear effects and carrier leakage.
Accordingly, the new WDM Investigator helps pinpoint causes of failure in DWDM
networks, both quickly and accurately.

"We are proud to provide our  customers with powerful spectral analysis  tools 
that reduce  downtime  and speed  up  time-to-revenue," said  Étienne  Gagnon, 
Vice-President of EXFO's Test  and Measurement Division.  "This new option  on 
the FTB-5240S/BP pays  for itself in  just a few  troubleshooting tickets.  In 
addition, it further  strengthens EXFO's  no. 1 market-share  position in  the 
portable OSA market, as recognized by Frost & Sullivan."

product page.  Orders  for  WDM  Investigator are  being  accepted  now,  with 
delivery expected in late March 2013.
