GBIC and SFP
Transceivers
User’s Guide
Version 1.00
October 2004
Use a transceiver module for connection
to a remote device. The GBIC and SFP
(also known as mini-GBIC) transceiver
modules are hot swappable. This means
that you can install and remove a
module while your device is operating.
The GBIC and SFP modules provide
duplex single-mode or multi-mode
connections.
GBIC Transceiver Modules
The GBIC module uses either 3.3V or
5V power input and SC-type connectors.
SFP Transceiver Modules
The SFP module uses 3.3V power input
and LC-type connectors.
Read the following guidelines before
installing and using a GBIC or SFP
module.
Handling Warning
GBICs and SFPs 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 a GBIC or
SFP module.
GBIC and SFP modules are dust
sensitive. When not in use, always keep
the dust plug on. Avoid getting dust and
other contaminant into the optical bores,
as the optics do not work correctly when
obstructed with dust.
Safety Warning
Fiber-optic GBIC and SFP modules are
equipped with a Class 1 laser, which
emits invisible radiation. Read the
following safety warnings carefully.
• To avoid possible eye injury, do not
look into an operating fiber-optic
module’s connectors.
• Laser radiation is present when the
device or system is powered up.
• Only trained and qualified personnel
should be allowed to install or replace
these modules.
Environmental Warnings
Dispose of your fiber-optic module
according to all national laws and
regulations.
This section describes how you install
and remove a GBIC module.
Installing a GBIC module
Follow these steps to install a GBIC
module.
1 Attach an ESD preventive wrist
strap to your wrist and to a bare
metal surface.
2 Remove the GBIC module from its
protective packaging.
3 Locate the transmit (Tx) and the
receive (Rx) markings on the GBIC
module.
4 Align the GBIC module in front of
the slot opening on a device.
5 Insert the GBIC module into the slot
until the GBIC module snaps into
place.
Connecting a Fiber-optic Cable
Follow the steps to connect a fiber-optic
cable to the GBIC module.
1 Remove the dust plugs from the
GBIC module and the cables.
2 Identify the signal transmission
direction of the fiber-optic cable and
the GBIC module. Insert one end of
the fiber-optic cable into the GBIC
module.
3 Insert the other end of the fiber-
optic cable into a remote device.
Refer to the user’s guide that comes
with your device for GBIC module slot
status.
Removing a GBIC Module
Follow the steps below to remove a
GBIC module.
1 Attach an ESD preventive wrist
strap to your wrist and to a bare
metal surface.
2 Disconnect all fiber-optic cables
from the GBIC module.
3 Insert the dust plug onto the GBIC
module.
4 Using your thumb and index finger,
grasp the tabs on both sides of the
GBIC module and carefully slide it
out of the slot.
This section describes how you install
and remove a SPF module.
Installing an SFP Module
Follow the steps below to install an SFP
module.
1 Attach an ESD preventive wrist
strap to your wrist and to a bare
metal surface.
2 Remove the SFP module from its
protective packaging.
3 Locate the transmit (Tx) and the
receive (Rx) markings on the SFP
module.
4 Align the SFP module in front of the
slot opening on a device.

Installing and Removing a
GBIC Module
Note:
Disconnect all fiber-optic cables
from a GBIC module before installing or
removing it.
Do NOT remove and install a GBIC
module more often than is absolutely
necessary. Doing so may shorten the
useful life of the GBIC module.
Note:
GBIC module installation
orientation varies depending on your
device. Your GBIC module comes with a
mechanism that prevents incorrect
insertion. Do NOT force or twist the
GBIC module into a slot.
Note:
Do NOT force or twist the module
out of a slot.
Installing and Removing an
SFP Module
Note:
Disconnect all fiber-optic cables
from an SFP module before installing or
removing it.
Do NOT remove and install an SFP
module more often than is absolutely
necessary. Doing so may shorten the
useful life of the SFP module.
