Chapter 1 Getting started
This chapter describes how to start using the ODM Module installed into the ONA-800.
The topics discussed in this chapter are as follows:
•“Precautions related to optical connections” on page 2
•“Connecting fiber optic cable” on page 2
•“Optical connectors and interchangeable adapters” on page 4

Chapter 1 Getting started
Precautions related to optical connections
2 User Manual 700MAN902 Rev. 000
Precautions related to optical connections
•The normal operating life of an optical connector is usually of the order of a few
hundred matings.
•The proper operation of the instrument and its accuracy are dependent on the
cleanliness of the optical connectors as well as the care taken in its manipulation.
•The optical connectors must therefore be clean and dust-free. If the optical
connection is not being used, protect the connections of the module using the
protective caps.
Connecting fiber optic cable
Inspecting and cleaning connector end faces
•Optical connector contamination is the #1 source of performance degradation
and test equipment repair
•A single particle mated into the core of a fiber can cause significant back reflec-
tion, insertion loss and equipment damage. Visual inspection is the only way to
determine if the fiber connectors are truly clean before mating them.
Follow this simple "INSPECT BEFORE YOU CONNECT" process to ensure fiber end
faces are clean prior to mating connectors.
Always inspect and clean the connector end face of the optical fiber
cable and the test port before mating both together.
VIAVI is not responsible for damage and reduced performance caused
by bad fiber handling and cleaning.

Chapter 1 Getting started
Connecting fiber optic cable
User Manual 700MAN902 Rev. 000 3
Caution
Never connect a PC connector into an APC test port or vice versa. This will result in
damaging the connector end faces.
Figure 1 "Inspect Before You Connect" process
Figure 2 PC/APC bad connection
WARNING
VIAVI declines responsibilities of connector damages if a poor quality con-
nector is used or APC to PC connections made. Test port connector repair
will be charged

Chapter 1 Getting started
Optical connectors and interchangeable adapters
4 User Manual 700MAN902 Rev. 000
Connecting Fiber optic cable to test port
After ensuring proper cleaning of both end connectors, follow the below steps in order
to correctly and safely connect the optical fiber into the test port:
1Carefully align the connector and test port to prevent the fiber end from touching
the outside of the port and scratching the end face.
2Push the connector to firmly place it inside ensuring physical end face contact.
Optical connectors and interchangeable adapters
Fiber Optic modules may come equipped with a universal connector and adapter
selected at time of order.
Adapter types
VIAVI offers 4 different adapters, all compatible with this connector.
Adapter types supplied are: FC, SC, DIN and ST.
NOTE
If your connector features a keying mechanism, ensure that it is correctly fit-
ted into the test port's insert.
NOTE
If your connector features a screw-on sleeve, tighten the connector to firmly
maintain the fiber in place. Do not over tighten as this will damage the fiber
and the test port.
WARNING
Never force the connector ferrule or insert it with an angle into the test port
adapter. Mechanical stress may permanently damage the ceramic sleeve of
the adapter or the end face of the connector. A new adapter purchase only
will get the unit back to operation.
