4.3 Small Form-Factor Plug Module
This section provides information about small form-factor plug (SFP) modules. The SFP modules are input/
output devices that plug into a Gigabit Ethernet (GE) small form-factor (SFF) port, linking the port with a
1000Base-X fiber.
The fiber SFP module have a receiver port (Rx) and a transmitter port (Tx) that make up one optical interface.
The 1000Base-SX (short wavelength) SFP module operates on standard multimode fiber networks compliant
with the 1000Base SX standard. The 1000Base-LX (long wavelength) SFP module operates on standard
single-mode fiber networks compliant with the 1000Base LX standard. The fiber SFP module is a 1000 Mbps
optical interface in the form of an LC-type duplex port that supports interfaces compliant with the 1000Base-X
standard.
4.3.1 Installation Prerequisites
This section describes safety and compliance guidelines you should observe before you install an SFP module in
your FVS unit.
NOTE:
You can install and remove SFP modules with power on to the system; however, it is strongly
recommended that you do not install or remove the SFP module with fiber or copper cables attached to it.
Disconnect all cables before removing or installing a SFP module.
CAUTION:
Prevent system problems, use only Datacom Systems Inc. supplied SFP modules.
4.3.2 Safety Guidelines
Before handling a SFP module, observe the following guidelines:
Copper and fiber SFP modules are static-sensitive. To prevent electrostatic discharge (ESD) damage, follow
your normal ESD handling procedures.
Fiber SFP modules are dust-sensitive. When storing a SFP module or when a fiber cable is not plugged in,
always keep plugs in the SFP module optical hole.
The most common source of contaminants in the fiber SFP optical aperture is debris picked up on the
terminations of the optical connectors. Use an alcohol swab or lint-free absorbent wipes to clean the
terminations of the optical connector.
WARNING:
Fiber SFP modules are class 1 laser and LED products. Invisible laser radiation may be
emitted from the port opening when no fiber cable is connected, avoid exposure to laser radiation and
do not stare in open optical ports.
