definitions
Splicer
mechanical device for joining two pieces of paper or film or magnetic tape
Splice
joint made by overlapping two ends and joining them
Splicing
process of the permanent connection of two pieces of optical fibres
scribe & break
End preparation
Striping (cable jacket, buffer tube & coating)
Cleaving
Cleaning the end surface
mechanical splicing
bonding two fibers together in an alignment structure
Transparent adhesive
- e.g. epoxy resin
Commonly used groove
- V-groove
Alignment problems
fusion splicing
Fusing the two fibers
Flame heating sources
- micro-plasma burners, oxy-hydric micro-burners, electric arc..
Advantage
- consistent and easily controlled heat with adaptability
Possible drawback
- weakening of fiber in the vicinity of splice
splice tray
Stores and organizes the fiber & splice
Protects fibers
Prevents fibers from exceeding the minimum bending radius
Establishes long haul links
splicing losses
Intrinsic
- Freznel reflection
Extrinsic
- foreign particles on surfaces
Reflection
- incident and reflected beam travel on the same path
