Difficulty: MediumParaphrased Fact Recognition

Read the passage below regarding fiber-optic installation:

During precision fiber-optic cable installation, technicians utilize automated fusion splicers to permanently join glass optical fibers. Before alignment, a mechanical stripper strips the outer polymer buffer coating, and an isopropyl alcohol wipe clears microscopic debris from the bare cladding. Next, a specialized diamond cleaver scores and snaps the glass fiber perpendicularly to guarantee an end-face angle below one degree. Finally, high-voltage electric arcs melt the core ends together inside the splicer chamber, while an automated optical power monitor assesses splice attenuation to verify that light transmission loss remains negligible.

Based on the passage, match each technical procedure with its accurate paraphrased description.

  • An isopropyl alcohol wipe clears microscopic debris from the bare cladding.A solvent cloth purges minute contaminants from the exposed outer glass layer.
  • A specialized diamond cleaver scores and snaps the glass fiber perpendicularly to guarantee an end-face angle below one degree.A precision cutting tool fractures the strand at a right angle to ensure minimal surface tilt.
  • High-voltage electric arcs melt the core ends together inside the splicer chamber.Electrical discharges fuse the glass filaments within the splicing unit.

Answer

The alcohol wipe matches the solvent cloth purging contaminants; the diamond cleaver scoring perpendicularly matches the precision tool fracturing the strand at a right angle; and the electric arcs melting cores match the electrical discharges fusing glass filaments.
Each statement from the passage corresponds to a single paraphrase that preserves the exact meaning through synonym substitution and grammatical restructuring: cleaning debris from cladding corresponds to purging contaminants from the outer glass layer; perpendicular diamond cleaving corresponds to right-angle precision fracturing; and high-voltage arc melting corresponds to electrical discharge fusion.

Step-by-Step Solution

1
Identify the key action and components in the cleaning step of the passage.
The text states an isopropyl alcohol wipe cleans tiny particles off the bare cladding.
Mapping 'isopropyl alcohol' to 'solvent', 'debris' to 'contaminants', and 'cladding' to 'outer glass layer' pairs the first procedure with the solvent cloth description.
2
Analyze the cleaving procedure and geometric requirement in the text.
The cleaver cuts perpendicularly (90 degrees) to ensure an angle under one degree.
Mapping 'diamond cleaver' to 'precision cutting tool', 'perpendicularly' to 'at a right angle', and 'end-face angle below one degree' to 'minimal surface tilt' matches the second procedure.
3
Examine the fusion step described in the passage.
High-voltage electric arcs thermally join the core ends inside the unit.
Mapping 'high-voltage electric arcs' to 'electrical discharges' and 'melt the core ends together' to 'fuse the glass filaments' links the third procedure correctly.
