Fiber Optical Connections
BIMMF is structurally the same as standard MMF cable but there is an added layer of glass between the core
and the cladding. This layer of glass has a much lower refractive index than the cladding.
Bend-insensitive 50-micron MMF cable is full backwards compatible with existing 50-micron MMF and fully
compliant with OM2, OM3 and OM4 standards.

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
• 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.

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.
