TC Communications currently offers more than 60 different networking products. Together or singly, these products combine to provide reliable, efficient solutions to most fiber communication networks and connectivity applications including integrated Ethernet, Data and Voice solutions.
Quality is everything at TC Communications. Certified to ISO 9001:2008, it designs products with the user in mind; that is, modularity, scalability, easy installation, self-testing, low power consumption, low component counts, long MTBF’s and replaceable EPROM’s for changing or upgrading.
In addition, every product undergoes component inspections, preliminary power-up tests, functional tests before and after burn-in, and a comprehensive final inspection test. All products are subjected to “live operating temperature” testing in a walk-in environmental chamber for 24 hours before shipping.

TC Communication Engineers Routinely test products with an Optical Spectrum Analyzer.
Superior Engineering
A company's Engineering Department
is the foundation for its design creativity,
product quality and reliability.
Lead by TC's visionary Chief Design
Engineer, its Engineering Department is
comprised of a unique group of highly
educated and trained engineers that are
particularly strong at R&D and customizing
products to fit special application requirements.
The typical TC Engineer has an advanced
degree, 10+ years industry experience
and has worked at TC for more than
6 years.
Partnerships with Customers
TC treats its customers like
partners. The basic purpose of
this partnership is to insure that its products
and services meet customer
expectations before,
during and after product
installation.
Services include consultation
on migration strategies
, e.g. from SONET/
SDH networks to Ethernet/
IP networks; designing
network diagrams during
pre-sale; and preparing
technical proposals or conceptual
designs for specific
projects.
TC also offers various training classes
including proper installation, commissioning,
integrating with different network
communication equipment and various
testing and benchmarking techniques.
Outstanding Customer Service
TC's high level of customer service is
the direct result of its culture of employee
teamwork. TC employees exhibit a positive
"can do" attitude and sales, production,
engineering and accounting departments
work together in close cooperation to
meet every customer's needs.
As evidence of this cooperation, TC
routinely ships orders in 3-5 days ARO and
often sooner. No competitor can match
TC's ability to ship rush orders and accommodate
special requests.
Quality of Product

Production Floor Inspection
- Certified to ISO 9001:2000
- Dynamic R&D
- Intensive Product Testing
- 5-Year Product Guarantee
TC Communications
is committed to
designing and manufacturing
high quality
products. As evidence
of this commitment,
all TC products are
designed with the
user in mind; that is,
easy installation, selftesting,
low power
consumption, low
component counts,
long MTBF's, extensive
remote management
capabilities for
preventive maintenance
and download
capability for
software/firmware
upgrades.
Engineering and
production departments
both feature
extensive on-site
testing equipment to
verify that all products
exceed pertinent
industry and environmental
specifications.
At TC, every product
is subjected to component
inspections,
preliminary powerup
tests, functional
tests, burn-in tests, and a comprehensive
final test.
It is worth noting that, when it comes
to quality, all vendors are not alike. Many vendors promise quality, but their processes
often cannot stand up to close scrutiny. For
example, some companies "sample test."
That is, they test less than 10% of finished
products and rely on statistical analysis to
predict failure rates. At TC,
quality is too important to
leave to statistical
analysis.

Walk-in Environmental Testing Chamber
TC tests every
product prior to
shipping, including
"live operating
temperature" testing
in an environmental
chamber for more
than 24 hours. TC's
environmental chamber
testing procedure requires every unit to be hooked up to a
live tester to insure that it runs error-free
when the temperature chamber cycles
from −40°C to 80°C during an overnight
burn-in test.
TC Communications employees are
dedicated to maintaining TC's reputation
for designing and manufacturing reliable,
high quality products. You can be assured
that TC will continue to meet the rigorous
product and support requirements for
industrial, military, government and commercial
networks worldwide.
