Maintenance & Troubleshooting
Keep Fiber Connections Clean
• Installing connectors on a fiber requires special handling procedures. Read and follow
the fiber and connector manufacturer’s instructions.
The physical interface between the optical fiber and the fiber port of the SFP cartridge is
the critical point in the system. The fiber and the optical port must be accurately aligned –
that’s the job of the connector plugs and sockets – and be in intimate contact with no
obstructions. This is your job. The small size of the fiber, and the even smaller size of the
fiber core, means that even common dust particles can seriously impair the transfer of light
from one fiber to another.
There are a variety of cleaning solutions available to help you maintain good fiber network
performance. For best results, it should be possible for you to perform a visual inspection of
the fiber ends to verify cleanliness.
Grass Valley strongly urges you to select a cleaning method that meets your needs, and to
use it rigorously and consistently.
A few tips:
• When an optical fiber is disconnected from the SFP module’s optical port, always:
• Insert a dust plug into the empty SFP module’s optical port.
• Install caps on the open end of the fiber optic cable.
This keeps airborne particles from settling on the fiber end or in the SFP module’s
optical port.
• Keep your dust plugs and caps clean – always store them in a sealed container to
prevent the transfer of dust to the fiber connectors when used in the future.
• Always follow the instructions carefully when cleaning – abrasions on the fiber ends
can degrade system performance significantly.
• A visual inspection will ensure that particles and liquid residue have been removed.
• If it’s still dirty, clean it again.
Note: The SFP module’s optical ports cannot be cleaned.
If dust enters the SFP module’s optical port to the point where
performance degrades, the corrective action is to replace the
damaged SFP module with a new one.
