How are armored optical cables spliced

Armored optical cables are spliced by carefully exposing the fibers, aligning them using fusion or mechanical splicing, and protecting the splice with heat shrink or closure systems to maintain both optical and mechanical integrity.Preparation and SafetyBefore splicing, ensure the work area is safe, especially for cables like OPGW that may carry electrical grounding functions. Establish an equal potential zone using temporary grounding cables and protective equipment to prevent electrical hazards ( ). Verify that the cable meets diameter and quality requirements, and gather all necessary tools, including fiber strippers, cleavers, fusion splicers, heat shrink tubing, and protective sleeves ( ).Accessing the FiberRemove the Armor: Carefully cut and remove the metallic or Kevlar armor without damaging the inner fiber ( ).Strip the Coatings: Use a fiber stripper to remove polyimide or acrylate coatings from the fiber, cleaning the exposed glass with alcohol wipes ( ).Prepare the Fiber Ends: Cleave the fibers with a precision cleaver to create flat, perpendicular end faces for optimal alignment ( ).Splicing MethodsFusion SplicingAlign the cleaved fibers in a fusion splicer using high-resolution cameras and motors ( ).The splicer generates an electric arc to melt and fuse the fiber cores, forming a continuous optical path with minimal insertion loss (
