Convert 10-, 100-, or 1000-Mbps segments between twisted-pair
and single- or multimode fiber in half- or full-duplex mode. You can
even convert single-mode fiber to multimode fiber! Choose from
5 different chassis and 28 converter modules for exactly the right
configuration.

Use the 10BASE-T/BNC module to integrate legacy ThinNet into
today’s UTP Ethernet network.
Choose from fiber modules that support 10-, 100-, or 1000-Mbps
Ethernet on the copper side and multimode or single-mode on the
fiber side. Use these modules to add distance—up to 40 kilometers—
to your network. Autosensing 10BASE-T/100BASE-TX modules
connect to either 10BASE-T or 100BASE-TX networks and
automatically sense and adapt to network speed.

Single-strand fiber modules send and receive over one single-mode
fiber strand, so you save on infrastructure costs.
All modules with copper ports feature an internal two-position
switch on the twisted-pair port, which eliminates the need for
a crossover cable. Just move the switch to the appropriate setting
on the module before installing the card.

the local site administrator is notified of a fault and can quickly
determine where it is located.

The 1300-nm Single-Mode to 1300-nm Multimode Modules are
packaged in twos and work in pairs. They require two chassis slots,
so they only work with the 4-, 8-, or 12-slot models. You can choose
from versions that support distances of up to 40 kilometers. One
module in the package features a single-mode receive port and a
multimode transmit port; the other has a multimode receive port
and a single-mode transmit port.

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.
