Chapter 1
Overview
The AT-MC1004 and AT-MC1005/x Series Gigabit Ethernet Media Converters
are designed to extend the distance of your network by converting Gigabit
Ethernet data between twisted pair cabling and either multimode or single-
mode fiber optic cabling.
The AT-MC1004 media converter features a 1000Base-SX fiber optic port and
a 1000Base-T twisted pair port. Thefiber optic port has an SC connector and a
maximum operating distance of 550 meters (1,804 feet). The twisted pair port
has an RJ-45 connector and a maximum operating distance of 100 meters (328
feet).
The AT-MC1005/x media converters feature a 1000Base-LX fiber optic port
and a 1000Base-T twisted pair port. The fiber optic port has an SC connector
and a maximum operating distance of 10 kilometers (6.2 miles) to 70
kilometers (43.4 miles), depending on the model. The twisted pair port has an
RJ-45 connector and a maximum operating distance of 100 meters (328 feet).
These units operate at 1000 Mbps and feature full-duplex operation.
The AT-MC1004 and AT-MC1005/x Series Gigabit Media Converters can be
used on a desktop or in an AT-MCR12 chassis. These units are easy to install
and do not require any software configuration or management. Figure 1
illustrates an AT-MC1004 media converter.

Key Features
The media converters have the following key features:
❑LEDs for unit and port status
❑1000Basetwisted pairport with a maximum operating distance of 100
meters (328 feet)
❑1000Base fiber optic port with a maximum operating distance of 550
meters (1,804 feet) to 70 kilometers (43.4 miles) using single-mode or
multimode fiber optic cabling, depending on the model
❑Full-duplex operation
❑External AC/DC power adapter
❑Standard, compact size for desktop use or with an AT-MCR12
rackmount chassis
Fiber Optic Port
The 1000Base-SX port on the AT-MC1004 media converter has an SC
connector and is designed to operate with multimode fiber optic cabling. This
port has a maximum operating distance of 550 meters (1,804 feet) using 62.5/
125 micron multimode fiber optic cable.
The 1000Base-LX port on the AT-MC1005/x Series Media Converters has an
SC connector and is designed to operate with single-mode fiber optic cabling.
This port has a maximum operating distance of 10 kilometers (6.2 miles) to 70
kilometers (43.4 miles), depending on your model, using 9/125 micron single-
mode fiber optic cable.
Twisted Pair Port
The 1000Base-T port on the AT-MC1004 and AT-MC1005/x Series Gigabit
Media Converters has an RJ-45 connector and is designed to operate with
Category 5 or better shielded or unshielded twisted pair cable.
An RJ-45 twisted pair port on a 1000 Mbps Ethernet network device can have
one of two possible wiring configurations: MDI or MDI-X. The RJ-45 port on a
PC, router, or bridge is typically wired as MDI, while the twisted pair port on
a switch or hub is usually MDI-X.

4
To connect two network devices that have dissimilar wiring configurations,
such as MDI to MDI-X, you use a straight-through twisted pair cable. To
connect two network devices that have the same wiring configuration, such as
MDI to MDI, you use a crossover cable.
The AT-MC1004 and AT-MC1005/x Series Gigabit Media Converters feature
automatic MDI/MDI-X. Each port automatically determines the configuration
of the port on the device to which it is connected and then configures itself
appropriately. For example, if a port on a media converter is connected to a
port on a bridge, which is typically wired as MDI, the port on the media
converter automatically configures itself as MDI-X. This feature allows you to
use either straight-through or crossover cables when connecting devices to the
media converter. This eliminates the need for a cross-over cable.
Status LEDs
Table 2 defines the units LEDs.
Table 2 Status LEDs
Half- and Full-Duplex Mode
Duplex mode refers to the way an end-node sends and receives data on the
network. An end-node can operate in either half- or full-duplex mode,
depending on its capabilities. An end-node that is operating in half-duplex
mode can either send data or receive data, but it cannot do both at the same
time. An end-node that is operating in full-duplex mode can send and receive
data simultaneously. The best network performance is achieved when an end-
node can operate at full-duplex, since the end-node is able to send and receive
data simultaneously.
The AT-MC1004 and AT-MC1005/x Series Gigabit Ethernet Media Converters
operate in full-duplex mode only. The media converter can operate with end-
nodes capable of either full-duplex mode or that can auto-negotiate the duplex
mode. However, it is important to remember that the two end-nodes connected
to the ports on the media converter must be able to operate in full-duplex
mode.
LED Color Description
PWR Green Power is applied to the unit.
REC Green Data is being received on the ports.
LNK Green A link has been established on the ports.

External AC/DC Power Adapter
An external AC/DC power adapter is included with the media converter for
desktop operation (see Figure 3). The power adapter supplies 12V DC to the
media converter. Allied Telesyn supplies an approved safety compliant AC
power adapter for the 120 and 240V AC versions with an unregulated output
of 12V DC at 1 A. The power required for the media converter is 12V DC,
1000 mA.
Note
The power adapter is not used if you install the media converter in an
AT-MCR12 chassis.

Network Topologies
The AT-MC1004 and AT-MC1005/x Series Gigabit Ethernet Media Converters
can be used in two different topologies: standalone and back-to-back. Both
types of topologies are described below.
Standalone Topology
A standalone topology uses only one media converter between the end-nodes.
Figure 4 illustrates a standalone topology that uses two AT-MC1005/1 media
converters to interconnect three remote campuses. Campus 1 has an
AT-8224XL switch with two AT-A15/LX expansion modules. The modules,
which provide a connection of up to 10 kilometers (6.2 miles), are connected to
the 1000Base-LX ports on the media converters. The 1000Base-T ports on the
media converters are connected to the AT-A14 expansion modules in the
AT-8216FXL/MT switches at Campus 2 and Campus 3.

Back-to-Back Topology
In some network configurations you may want to interconnect two media
converters in what is referred to as a back-to-back topology. In this topology,
the media converters not only extend the distance of your network but also
convert the fiber optic cable from twisted pair to fiber optic and back again.
Figure 5 illustrates one AT-8216FXL/MT switch with an AT-A14 expansion
module at each campus. The switches are interconnected by two AT-MC1005/3
media converters. The 1000Base-T ports on the media converters are
connected to the AT-A14 expansion modules in the switches, while the
1000Base-LX ports on the media converters are directly connected together.

1. For maximum performance of Gigabit Optical Datalinks when greater than 40 km (24.8 mi) and operating within the
1550 nm optical spectrum, it is mandatory that the Single-mode Fiber (SMF) be rated as non-dispersion-shifted,
dispersion shifted, or non-zero dispersion shifted.
