Optical SFP Module Types and Connectors and Copper SFP Module show the types of SFP modules
and connectors.
Note
The bi-directional SFP modules combine two SFP optical devices that must be used as a pair
to establish the bidirectional connection over a single fiber. Module C and Module D in Optical
SFP Module Types and Connectors show the pair of SFPs for a bi-directional SFP module.
Warning
Optical SFPs contain Class 1 lasers. Invisible laser radiation can occur when laser connections
areunplugged. Do not stare into the beam. This device is compliant with FCC 21 CFR 1040.10
and EN60825-1A2:2001.
