Fiber Optical Connections
Caution:
The SFP+ transceiver modules are static sensitive devices. Always use an ESD wrist strap or similar
individual grounding device when coming into contact with SFP+ modules.
Caution:
Before connecting fiber optic cables, press each module into the slot firmly with your thumb to reseat
them.
Removing Dust Plugs
Before removing the dust plugs and making any optical connections, observe the following guidelines:
Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical
bores until you are ready to make a connection.
Always inspect and clean the LC connector end-faces just before making any connections. See
Always grasp the LC connector housing to plug or unplug a fiber-optic cable.
Important:
To facilitate maintenance of the network cabling, all fiber optic cables should be labeled with
terminating destinations.
Connecting Fiber Optic Cables
Step 1
Remove the dust plug from the network interface LC connector of the SFP+ module. Save the dust plug for future use.
Step 2
Inspect and clean the LC connector’s fiber-optic end-faces.
Step 3
Insert the duplex LC/PC connector on the network cable into the duplex port on the module.
Step 4
Attach the other end of the network fiber-optic cable to the network device that you want to connect.
Step 5
Repeat Step 1 through Step 4 for the remaining ports on the daughter card.
Step 6
Repeat Step 1 through Step 4 for ports on the second DC.
Cleaning Fiber Optic Connectors
Fiber optic connectors join optical fibers together. They can be damaged by improper cleaning and connection
procedures. Dirty or damaged fiber optic connectors can degrade communication.
procedures. Dirty or damaged fiber optic connectors can degrade communication.
In a fiber optic system, light is transmitted through extremely small fiber cores. Because fiber cores are often 62.5
microns or less in diameter, and dust particles range from a tenth of a micron to several microns in diameter, dust and
any other contamination at the end of the fiber core can degrade the performance of the connector interface where the
