The standard heating cycle is typically 30-60 seconds depending on the sleeve size. Do not touch the sleeve immediately as it will be hot and the adhesive needs a moment to set. Heat shrink tubing is an expanded tubular piece of plastic that reduces in size when heated, and is commonly utilized to insulate and protect wires, joints, and terminals. Fiber Heat Shrink Tube, also referred to as Fiber Splice Tubes, Fusion Protection Tube, or Splice Protection Tube, plays a crucial role in modern communication networks. Splicing: Strip, clean, cleave, and fusion splice the optical fibers according to the fusion splicer manufacturer's instructions. The heating direction should be slow from one end to another or from the middle towards both ends to prevent air from being trapped inside the heat shrink tubing, which could cause.
