Hi keep going on OFC(Optical Fiber Communication)

1. Optical Fiber Communication
Fiber Cable Repairing

2. Fiber Repairing
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 fibers.

3. TOOLS AND EQUIPMENT
NO TOOLS NAME USE
1 Bolt cutter Cutting of the cable
2 Scissors Cutting paper
3 Lap cutter Removal of cable sheath
4 Phillip screw driver set. Tightning the screw
5 Marking scale For positioning cable clamp
6 Tape measuring Measurement
7 Spanner set Tightning nuts
8 Hammer Common used
9 Knife Removal plastic
10 Torque wrench For fixing the modal A cable replace
11 Pliers combination For cutting tension members
12 Cleaver Cutting optical fiber core
13 Core stripper Stripping secondary coating

5. Materials used for cable splicing
– Fiber Optic Cable
– Closure
– Termination box, panel, FDF.
– Pig tail
– Protection sleeve
– Alcohol
– Cotton gauze
– Cotton Bud
– Cotton waste.

6. Types of splicing

7. Mechanical splicing
• Bonding two fibers together in an alignment
structure
• Transparent adhesive
- e.g. epoxy resin
• Commonly used groove
- V-groove
• Alignment problems

13. 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

16. Splice tray or Enclouser
• Stores and organizes the fiber & splice
• Protects fibers
• Prevents fibers from exceeding the minimum
bending radius
• Establishes long haul links

17. Manhole

18. comparison
Mechanical splicing Fusion splicing
Reflection losses
(-45 db to -55 db)
No reflection losses
Insertion loss
(0.2 db)
Very low insertion loss
(0.1 db to .15 db)
cost – high Comparatively less

19. splicing losses
• Intrinsic
- Freznel reflection
• Extrinsic
- foreign particles on surfaces
• Reflection
- incident and reflected beam travel on the same
path

20. Splicing Machines manufacturers
1. Fujikura (Japan)
2. Sumitomo (Japan)
3. INNO (Korea)
4. Fitel (Japan)
5. Korean dark horse (Korea)
6. The 41st of CETC (China)
7. Nanjing Jilong (China)
