AT-MCF6xx and AT-MCF12xx Multichannel Ethernet Media Converters

The Ethernet AT-MCF6xx and the AT-MCF12xx Multichannel Media
Converters are designed to extend the reach of your network by converting
your twisted pair cabling into fiber optic cabling. These products, which
transfer Ethernet data between 10Base-T and 10Base-FL technologies, enable
you to quickly and easily interconnect the nodes in your network to distances
of 2 kilometers (1.24 miles) to 15 kilometers (9.3 miles), depending on the
model. With this product, remote devices and networks, which previously
were difficult to interconnect, are easily interconnected to form one integrated
network.

The ports on the media conv erters are grouped into pairs, referred to as
“channels,” with each pair consisting of a 10Base-T twisted pair port and a
10Base-FL fiber optic port. Each channel functions as an independent media
converter. The Ethernet AT-MCF 6xx unit features six channels, providing yo u
with six individual media converters, while the AT-MCF12xx unit features
twelve channels, giving you twelve individual media converters.

The twisted pair ports are designed to operate with Category 3 or better
cabling at a speed of 10 Mbps. The fiber optic ports also operat e at a speed of
10 Mbps and are ava ilabl e in a vari ety o f conne ctor t ypes. Th e fibe r optic po rts
support IEEE stan dard Multimode Fiber (MMF) or Single-Mode Fiber ( SMF)
cable.

The multichannel media converters can be installed either as standalone
units, such as on a table, or in a standard 19-inch rack. The units are easy to
install and do not require any software configuration or software
management.

Twisted Pair and Fiber Optic Ports

The twisted pair and fiber optic ports on the unit are paired together (see
Figure 3). Each pair is referred to as a “channel” and each channel functions
as an independent media converter. The AT-MCF6xx Multichannel Media
Converter has six channels while the AT-MCF12xx Multichannel Media
Converter has twelve channels.

and thus operate at 10 Mbps only. The ports require Cat egory 3 or bett er
cabling and allow fo r a distance of 100 meters (328 feet).

The devices that you connect to the twisted pair ports must operate at
10 Mbps. To connect a switch, hub, or router to a twisted pair port requires a
straight-through cable. To connect a workstation to a twisted pair port
requires a crossover cabl e.

10Base-FL Fiber Optic Ports.

The 10Base-FL fiber optic ports operate at 10 Mbps
and, depending on the model, function with multimode or single-mode fiber
optic cabling.

The type of connector on the fiber optic ports w ill depend on the system model
you purchased. Refer to Table 1 on page 2 for a list of the available types of
connectors.

AT-MCF6xx and AT-MCF12xx Instal lat io n Guide

Port LEDs

Each channel on the media converter has a series of LEDs that you can use to
monitor the status of the ports of the channel. Each twisted pair port has one
LED labelled T-LNK that indicates whether or not a link has been established
between the port and the node connected to the port. Each fiber optic port has
two LEDs, one labelled F-LNK that lights when a link has been established
with the node connected to the port and another LED labelled Active that
lights when the port is receiving traffi c.

Link Test Switch

The Link Test switch is a fast and easy way for you to test the integrity of the
fiber optic connections to the fiber optic ports on the multichannel media
converter (see Figure 4). The AT-MCF6xx system has one Link Test switch
which is used to test all six fiber optic ports on the unit. The AT-MCF12xx has
two Link Test switches; one switch is used to test the fiber optic ports in
channels 1 through 6 and the second switch is used to test the fiber optic ports
in channels 7 through 12 on the unit.

The Link Test switch is used after installation to verify that the unit and
connections are operating properly, or whenever you need to test the fiber
optic ports or the integrity of the fiber connections to the nodes connected to
the ports.

The LED next to the Link Test switch indicates the operating mode of the
fiber optic ports. If the Test LED is lit amber, a link test is being performed on
the fiber optic ports associated with the switch. The section “Verifying the
Installation” on page 19 contains instructions for performing a link test.
