Converts 10BASE-T
to 10BASE-FL.

Compact and easy to
install.

Works with half- or
full-duplex Ethernet.

Monitor using Status
and Activity LEDs.

Autosensing universal
power supply.

Supports maximum
distances for both
10BASE-T and
10BASE-FL.

H

ere’s the economical way

to convert copper-based
10BASE-T Ethernet to multimode
fiber-based 10BASE-FL.

For most applications, you
get conversion just as effective as
what you’d get from a repeater—
but at a fraction of the cost.

This desktop-size converter
enables you to connect shielded or
unshielded twisted-pair 10BASE-T
segments terminated with 8-pin
RJ-45 plugs to 850-nm ST term­inated cable for operation over
duplex multimode fiber. The
MicroConverter works with either
standard or full-duplex Ethernet.

Use it, for instance, to attach
10BASE-T wiring to a hub-like
device or to attach crossed wiring
to a LAN port on a network
interface card, router, or terminal
server.

Economical, problem-free

media conversion. Now with

a universal power supply!

Key Features

Automatic polarity correction
eliminates minor wiring
headaches. Plus, it supports the
maximum distances for both
network types—100 meters
(328 feet) for 10BASE-T and
2 kilometers (1.2 miles) for
10BASE-FL.

And you don’t have to worry
about signaling violations. Those
often come up, along with other
problems, when repeaters are
eliminated—but not with the
MicroConverter.

Installing the MicroConverter
is quick and straightforward. Just
attach and plug in its power
adapter, attach an active 10BASE­T cable’s RJ-45 connector, and
attach active 10BASE-FL fiber ST
connectors to the 10BASE-FL side.
To connect to a 10BASE-T port
labeled MDI (such as the port on
the network card in a PC), you’ll

need a crossover cable. To
connect to a 10BASE-T port
labeled MDI-X (such as on hubs
in wiring closets), you’ll need a
straight-through cable, since the
MDI-X connector is itself internally
crossed over.

Troubleshooting is a breeze,
too. Activity and Status LEDs keep
you informed of performance on
each interface. In addition, the
converter’s Link Detect feature
passes link-fault signals through
to other devices. You can keep
an eye on cable faults from your
management station. That’s a
feature you won’t find on ordinary
media converters. It’s a perfect
complement to our Mini FOIRL LD
Transceivers (LE2127A-R3).

With the converter, you get a
universal 110–230-VAC to 12-VDC
external power supply.

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
Communications 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.

At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.

Don’t waste time and
money—call Black Box today.

Why Buy From Black Box? Exceptional
Value. Exceptional Tech Support. Period.
