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 or 1000Base-T copper network.

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.

The copper SFP module is compliant with the 1000Base-T standard and operates on standard
Category 5 wiring and has an RJ45 connector.

Intallation Prerequisites

This section describes safety and compliance guidelines you should observe before you install an
SFP module in your VS-1200 series 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.

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.
