2.4 Fiber Optic Interface
Installing and removing the Fiber I/O interface cartridge requires special
care.
The optical interface of the FIO-991p consists of two parts:
•
A socket on one end of the chassis into which an SFP interface
module is plugged
•
An SFP (Small Form-factor Pluggable) module into which the optical
fibers are plugged, and which incorporates 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 module 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 a grounded ESD-preventive wrist strap
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 is absolutely necessary.
Never remove or install an SFP module with the fiber optic cables
connected. Damage 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 whenever a fiber optic cable
is not connected.
