Attaching Optical Network Interface Cables
Before you remove the dust plugs from the connector optical bores and make any connections, observe
the following guidelines:
•
Do not remove the plugs from the transceiver optical bores or the fiber-optic cable until you are ready
Caution
to connect the cable. The plugs protect the transceiver optical bores and cable from contamination.
•
•
To install the optical interface cables, follow these steps:
Remove the dust plugs from the network interface cable optical connectors. Save the dust plugs for
Step 1
future use.
Immediately inspect and clean the optical connector's fiber-optic end faces.

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 SC or the LC connector end-faces just before making any connections.
Refer to the Tip on inspecting and cleaning fiber-optic connections for the location of a document
that describes the fiber-optic inspection and cleaning process.
Always grasp the SC or the LC connector housing instead of the fiber-optic cable to plug or unplug
the fiber-optic cable.
Mode-Conditioning Patch Cords
Description
IEEE 802.3z-compliant optical fiber assembly consisting
of a single-mode fiber permanently coupled off-center to a
62.5-micron multimode optical fiber with duplex SC male
connectors at both ends. The patch cord is 3 meters (9.84
feet) in length.
