Introduction
The 100/1000 Base-T UTP to 1000 Base-X Fiber SFP Media Converter
allows seamless integration between a Fast/Gigabit Ethernet network
using unshielded twisted pair (UTP) copper cabling and a Gigabit fiber
network.
Use the LEDs to quickly check status and the DIP switches to set
transmission settings and “link loss forwarding”.
There is a slot for an SFP (Small Form-factor Pluggable) transceiver
module with an LC-type connector.
Key Features
The media converter has the following key features:
 Converts speed and media type
 Auto-crossover Ethernet port (auto MDI/MDI-X detection allows
use of either straight-through or crossover Ethernet cables)
 Auto-negotiating Ethernet port (can detect and adjust to the
optimum speed (100/1000Mbps) and mode (full duplex or half
duplex) of the connected device)

MC1000-SFP User’s Guide

 Can insert an SFP (Small Form-factor Pluggable) transceiver
module with LC-type connector
 DIP switches to configure fiber link negotiating defaults and Link
Loss Forwarding
 Link Loss Forwarding to notify the peer link if a link goes down
 LED status display
Fiber Modes
Multi-Mode Fiber (MMF) allows more than one mode of light to
propagate through the cable at one time. It is usually used as horizontal
cable (cable from your equipment room to each designated outlet or
work area) and sometimes as backbone cable (between equipment
closets or rooms).
Light in a Single-Mode Fiber (SMF) travels straight down the fiber and
does not bounce off the surrounding cladding as it travels. This is most
commonly used by telephone companies and as backbone cable.
Example Applications
In the following figures, “A” is the media converter, “B” is a 100/1000
Mbps Ethernet switch and “C” is a layer-3 switch with 1000Mbps fiber
module.
Maximum distance obtained on the fiber link between media
converters depends on the transceiver module you install.

MC1000-SFP User’s Guide

Hardware
The media converter can be placed on a desktop. Make sure that there is
proper heat dissipation from and adequate ventilation around the device.
Do not place heavy objects on the media converter.
Front Panel
The front panel consists of an RJ-45 port for 100/1000 Mbps UTP
connections, LED indicators, DIP switches and an SFP slot for an SFP
transceiver module with an LC-type connector.
1000Base-T Port
Connect an Ethernet cable from a switch to this port. This port is auto-
negotiating and auto-crossover.
Transceiver slot

MC1000-SFP User’s Guide
10
An auto-negotiating port can detect and adjust to the optimum Ethernet
speed (100/1000Mbps) and duplex mode (full duplex or half duplex) of
the connected device. An auto-crossover (auto-MDI/MDI-X) port
automatically works with a straight-through or crossover Ethernet cable.
LED Indicators
The following table describes the LEDs in detail.
LED STATUS DESCRIPTION
PWR Green The media converter is on.
Off The media converter is off.
100/1000 Green The media converter has a 1000Mbps Ethernet
connection.
Orange The media converter has a 100Mbps Ethernet
connection.
Off The media converter has a 10Mbps Ethernet
connection or no connection.
LNK/ACT
(Ethernet)
Green The media converter Ethernet link is up.
Blinking The media converter Ethernet port is
transmitting or receiving.
Off The media converter Ethernet link is down.
FDX/COL
(Ethernet)
Orange The Ethernet port is operating in full-duplex
mode.
Off The Ethernet port is operating in half-duplex
mode or the Ethernet link is down.

MC1000-SFP User’s Guide
11
LNK/ACT
(Fiber)
Green The media converter fiber link is up.
Blinking The media converter is transmitting or
receiving on the fiber link.
Off The media converter fiber link is down.
FDX/COL
(Fiber)
Orange The fiber port is operating in full-duplex mode.
Off The fiber port is operating in half-duplex mode
or the fiber link is down.
Link Loss Forwarding
Without Link Loss Forwarding, if one side of a link fails (), the
other side will keep on transmitting packets () and wait for responses
that will never arrive.
With Link Loss Forwarding, a link down () detected on the Ethernet
port will force a link down on the fiber port and vice-versa. The up link
() will stop transmitting and turn "off" as soon as the remote link is
down.
DIP Switches
The DIP switches are all off by default.

MC1000-SFP User’s Guide
12
DIP
Switch 1
The fiber link is auto-negotiating when the switch is off. Turn it
on to force the fiber link to be up at only 1000Mbps in full
duplex mode.
DIP
Switch 2
Turn this switch on to have the Ethernet port send a Link Loss
Forwarding message to the fiber port in the event that the
Ethernet link goes down (that would then force the fiber link
down).
DIP
Switch 3
Turn this switch on to have the fiber port send a Link Loss
Forwarding message to the Ethernet port in the event that the
fiber link goes down (that would then force the Ethernet link
down).
Do not turn a DIP switch on or off when a port is transmitting
or receiving data as it may cause data error or loss.
SFP Transceiver Slot
Insert a 3.3V SFP (Small Form-factor Pluggable) transceiver module
with an LC-type connector into the SFP slot.
Use DIP switch 1 to change the default fiber connection
settings.
SFP transceiver modules are static sensitive. To prevent damage from
electrostatic discharge (ESD), it is recommended you attach an ESD
preventive wrist strap to your wrist and to a bare metal surface when
you install or remove an SFP transceiver module.
SFP transceiver modules are dust sensitive. Avoid getting dust and other
contaminants into them.
SFP transceiver modules are equipped with a Class 1 laser, which emits
invisible radiation. To avoid possible eye injury, do not look into an
operating fiber-optic module’s connectors. Laser radiation is also
present when the media converter is turned on.
Installing and Removing a Module

MC1000-SFP User’s Guide
13
Disconnect all fiber-optic cables from an SFP transceiver module before
installing or removing it. Do NOT remove and install an SFP
transceiver module more often than is absolutely necessary. Doing so
may shorten the useful life of the SFP transceiver module.
Installing an SFP Transceiver Module
Refer to your SFP transceiver module user’s guide for
specific installation and removal instructions. The
instructions outlined here are meant as an example.
1. Attach an ESD preventive wrist strap to your wrist and to a bare
metal surface.
2. Remove the SFP transceiver module from its protective
packaging.
3. Locate the transmit (Tx) and the receive (Rx) markings on the SFP
transceiver module.
4. Align the SFP transceiver module in front of the slot opening on a
device.
5. Insert the SFP transceiver module into the slot until the SFP
transceiver module snaps into place.
SFP transceiver module installation orientation varies depending on
your device. Your SFP transceiver module comes with a mechanism
that prevents incorrect insertion.

MC1000-SFP User’s Guide
14
Do NOT force or twist the SFP transceiver module into a slot.
Connecting a Fiber-optic Cable
Follow the steps described to connect a fiber-optic cable to the SFP
transceiver module.
1. Remove the dust plugs from the SFP transceiver module and the
cables.
2. Identify the signal transmission direction of the fiber-optic cable
and the SFP transceiver module. Insert one end of the fiber-optic
cable into the SFP transceiver module.
3. Insert the other end of the fiber-optic cable into a remote device.
Removing an SFP transceiver module
1. Attach an ESD preventive wrist strap to your wrist and to a bare
metal surface on the chassis.
2. Disconnect all fiber-optic cables from the SFP transceiver module.
3. Insert the dust plug into the ports on the SFP transceiver module.
4. Pull out the latch and down to unlock the SFP transceiver module.

MC1000-SFP User’s Guide
