ODN Interface Troubleshooting

The successful use of the ODN interface connection relies on several factors being within
tolerance. The components must:
• Be clean and dry (refer to Cleaning and Inspection of Components below).
• Have mechanically tight connections.
• Contain the proper optical signal levels. Refer to
The ODN interface within the SBU ONT at the customer premises consists of the elements

Cleaning and Inspection of Components

Because the physical size of the transmission core of the optical fiber is typically only 9
microns in size, debris such as a single particle of dust or smoke or strand of hair can impair
the path enough to cause transmission problems. This section provides information and
procedures for the following:

• Avoid allowing unmated connectors to touch surrounding unrelated surfaces and do not
• Use a fiberscope or videoscope to verify proper cleaning of connectors prior to mating
• Use an appropriate quality fabric type cleaner and pure alcohol (reagent grade, 99.5%
