• The fiber optic cables also need to be extended over long distances. 
The method of providing extension by joining two or more fiber optic 
cables is called splicing. 
• The technicians use two types of splicing methods to provide 
extensions – fusion splicing and the mechanical splicing.

What is fusion splicing and what are its advantages?
• Fusion splicing is a method of joining two or more fiber optic cables on 
a permanent basis using the fusion splicer. 
• A fusion splicer is a machine that aligns two fiber optic cable ends and 
welds or fuses them by means of an electric arc. It can fuse two fiber 
optic cables to up to twelve cables together.

Fusion splicing is the most preferred splicing method due to 
the following advantages
• Cost-effective as compared to the mechanic splicing. It might require 
a larger investment cost to purchase the toolkit and fusion slicer, but 
the variable cost per splice for subsequent use is much lower.
• Form permanent fusion of cables with the help of the fusion splicer.
• Lower insertion loss which is less than 0.1 dB, providing far better 
protection against the signal loss and cable failures. Insertion loss is 
essentially the loss of signal due to the insertion of a splice in the cable.

What is the mechanical splicing of fiber optic cables?
• In mechanical splicing of fiber optic cables, no heat is used. They are 
temporary connections between the fiber optic cables.
•  In this method, the fiber optic cables are aligned and combined using 
a gel, epoxy resin, or by mechanical clips.

Fusion Vs Mechanical splicing in fiber optic cabling 
installations
• Though fusion splicing is preferred method of splicing of the two, the 
mechanical splicing is favored for indoor use. 
• However, due to the higher insertion loss, higher cost, and unreliable for 
permanent connections, the mechanical splicing is relatively unpopular 
splicing method.
