Introduction
The LUMO series cards incorporate a fiber optic interface. The interface consists of two parts:
• Sockets on the front panel into which SFP interface modules are plugged
• SFP (Small Form-factor Pluggable) modules into which the optical fibers are plugged,
and which incorporate the optical/electrical interface
Cautions and Warnings
SFP Transmitter modules contain a class 1 laser, which emits invisible radiation
whenever the module is powered up. Because the SFP is hot-swappable, the mod-
ule may be powered up as soon as it is installed.
DO NOT LOOK INTO AN OPERATING SFP MODULE’S CONNECTORS, AS EYE DAMAGE
MAY RESULT.
The SFP module is sensitive to electrostatic discharge (ESD). It is recommended that
you use an ESD-preventive wrist strap grounded to the Lumo chassis while handling
the SFP module.
SFP modules are subject to wear, and their useful lifetime is reduced each time they
are inserted or removed. Do not remove them more often than absolutely necessary.
Never remove or install an SFP module with the fiber optic cables connected. Dam-
age to the cables could result.
The presence of dust and debris can seriously degrade the performance of an optical
interface. It is recommended that you insert a dust plug into the SFP module when-
ever a fiber optic cable is not connected.
