Features
Fiber Optic Cables use light as a digital information carrier. The
cable is made up of a small strand of glass, each providing a path
for light rays carrying the data signal. Fiber Optic Cables offer large
bandwidth, very high security, and immun ity to electrical interference.

Ceramic connectors on the Ceramic-Terminated Cables make the
highest quality cables and provide low signal loss, high reliability, and
long life. Composite connectors are good quality and are constructed
of a durable polymer and also offer high precision and low light loss.

Recognize any of these situations?
• You wait more than 30 minutes to get through
to a vendor’s tech support.
• The so-called “tech” can’t help you or gives you
the wrong answer.
• You don’t have a purchase order number and the
tech refuses to help you.
• It’s 9 p.m. and you need help, but your vendor’s
tech support line is closed.
According to a survey by Data Communi cations magazine, 90%
of network managers surveyed say that getting the technical support
they need is extremely important when choosing a vendor. But even
though network managers pay anywhere from 10 to 20% of their
overall purchase price for a basic service and support contract, the
technical support and service they receive falls far short of their
expectations—and certainly isn’t worth what they paid.
