15. Key differentiators
Real-time monitoring with
“little data” focus (SASS)
– Eschewing big data swamps in
favor of highly specific data and
prioritized insights to reveal
outages/service degradations
– Helps CSPs improve quality of
experience and reduce churn
Thirty-five years of
telecom expertise
– Secret sauce that separates
EXFO from competitors in
developing market-driven
solutions and services
– Raises EXFO to role of trusted
advisor (from mere supplier)
© 2021 EXFO Inc. All rights reserved. 15
Built-in intelligence and
automation (T&M)
– Allows CSPs to standardize
test routines across workforce
and contractors, getting the
installation right the first time
– Big savings on testing time and
money for CSPs
years
