Fusion Splicing Machine:

• How it works: Aligns the fiber cores precisely, then uses an electric arc to melt and fuse the fibers together.

• Pros:

  • Very low signal loss (typically <0.1 dB)

  • Long-lasting and stable connection

• Used in: Backbone and long-haul network installations

Mechanical Splicing Tool:

• How it works: Aligns two fiber ends inside a pre-fabricated sleeve with index-matching gel.

• 1. • Pros:

       • Quick and doesn’t require expensive equipment

     • Cons:

       • Higher signal loss (~0.3 dB)

       • Less durable than fusion

     • Used in: Emergency repairs and temporary connections

   Components of a Fusion Splicing Machine:

  • Fiber holders/clamps: Secure the fiber ends

  • Cleaver: Ensures clean fiber cuts (critical for low-loss splicing)

  • High-precision alignment system: Usually core-alignment or cladding-alignment via cameras and motors

  • Electric arc unit: Heats and fuses the fibers

  • Display: Shows alignment and splice result

  • Heater: Shrinks protective sleeves over the splice
