Basic Skills Lab - Splicing



True/False
Indicate whether the statement is true or false.
 

 1. 

Splices are used as permanent joints for two fibers while connectors are used where it is desired to be able to disconnect the two fibers or connect to transmission equipment.
 

 2. 

Often the fibers are broken as the trays and closure are assembled or re-entered for troubleshooting and repair.
 

 3. 

Cables which have metallic armor or strength members do not need to be grounded and must be isolated from other conductive cables in splice closures.
 

Multiple Choice
Identify the choice that best completes the statement or answers the question.
 

 4. 

When splicing optical fibers, proper alignment of the _____ is the most important factor.
a.
Buffer coating
b.
Cladding
c.
Core
d.
Cable
 

 5. 

Fusion splicers  use   ________ alignment to match thte two fibers before fusing them.
a.
Cladding
b.
Core
c.
Either core or cladding
d.
Manual
 

 6. 

After two fibers are fusion spliced, they must be protected with a  ________.
a.
Heat-shrink or crimp-on sleeve
b.
New buffer coating
c.
Strength members
d.
Glass coating
 

 7. 

For any type of mechanical splice, the most important thing for achieving low splice loss is ________.
a.
Index matching gel
b.
Good cleaves on both fibers
c.
Proper closure or crimping of the splice
d.
Matching fiber types
