Difficulty: EasyDirect Fact Retrieval

During precision fiber optic cable installation, technicians utilize automated fusion splicers to join individual glass optical fibers. Prior to splicing, the protective outer acrylate coating is stripped using mechanical stripping pliers, exposing the bare 125-micrometer glass cladding. Technicians then clean the bare fiber with high-purity isopropyl alcohol before placing it into a high-precision optical cleaver. The cleaver produces a flat, perpendicular end face at an angle of less than one degree. Once properly cleaved, the fiber ends are placed into the fusion splicer's V-grooves, where an electric arc melts and fuses the glass cores together.

According to the passage, what tool is used to remove the protective outer acrylate coating from the optical fiber?

  1. A
    A high-precision optical cleaver
  2. Mechanical stripping pliersAnswer
  3. C
    Thermal wire strippers
  4. D
    Fusion splicer V-grooves

Answer

Mechanical stripping pliers
The author explicitly states in the second sentence that 'the protective outer acrylate coating is stripped using mechanical stripping pliers.' Therefore, mechanical stripping pliers is the direct fact stated in the passage.

Step-by-Step Solution

1
Scan the passage for the keywords 'protective outer acrylate coating' and 'stripped'.
Located the sentence stating: 'Prior to splicing, the protective outer acrylate coating is stripped using mechanical stripping pliers...'
Direct fact retrieval requires locating the exact detail requested in the question stem within the text.
2
Identify the specific tool associated with stripping the coating.
The tool directly named for this action is mechanical stripping pliers.
Direct factual extraction confirms the exact tool explicitly described by the author.
