How do fusion splices differ from mechanical splices?

• A. Fusion splicing requires no heat
• B. Mechanical splicing is less reliable
• C. Fusion splicing uses heat, while mechanical splicing uses a fixture
• D. Mechanical splicing is quicker to perform

Answer: (C)

Fusion splicing involves the application of heat to join two optical fibers together, creating a permanent bond that aligns the cores of the fibers perfectly. This process typically results in minimal splice loss due to the seamless nature of the joint and the high precision of the alignment. The heat melts the ends of the fibers, allowing them to fuse into one continuous piece. On the other hand, mechanical splicing does not use heat but rather employs a fixture to align the fiber ends and maintains their connection through a physical mechanism. This method can introduce slightly higher splice loss compared to fusion splicing because the light may not pass through the joint as efficiently due to alignment and gap issues. Understanding these fundamental differences helps in selecting the appropriate splicing method based on the requirements of a specific installation or repair situation. Fusion splicing is typically preferred for permanent connections, while mechanical splicing may be utilized for temporary fixes or situations where speed is critical.
