Connectors Flashcards
What are the desirable features for any fiber optic connector or splice?
Consistency
Low Loss
Easy Installation
Economical
Repeatability
What are the four components of a fiber optic connector?
Ferrule
Body
Cap (Shroud)
Strain Relief Boot
What three materials are generally used to make the Ferrule?
Ceramic
Plastic
and
Steel
What two materials are used to make ceramic ferrules?
Aluminum Oxide
and
Zirconium Oxide
What are the two types of finishes used on connectors?
PC
and
APC
What is a PC finish?
Curved or rounded _P_hysical _C_ontact
What is an APC finish?
Angled _P_hysical _C_ontact
What are the three groups of factors that affect losses in a connector or splice?
Intrinsic
Extrinsic
and
System
What is an intrinsic factor?
Fiber realated factors such as variations in the fiber itself?
What are the five intrinsic factors?
Numerical Aperature Mismatch
Core Diameter Mismatch
Cladding Diameter Mismatch
Concintricity
Ellipticity
What is an extrinsic factor?
Connector related factors caused by the connector itself
What are the four main extrinsic factors?
Surface Roughness
End Separation
Angular Misalignment
Lateral Displacement
What are system factors?
Factors contributed by the system such as the transmitter, receiver, amplifier and other system components
What is numerical aperature mismatch?
When the acceptance angle of the input fiber is larger than the acceptance angle of the output fiber?
What is lateral displacement?
When one fibers axis does not coincide with the axis of the other
