40mm/45mm/50mm/60mm Splice Sleeves

40mm/45mm/50mm/60mm Splice Sleeves

Shrinkable sleeve is applied to the optical fiber closure to fix and protect the optical fiber when splicing. The sleeve can be divided into two types(single and mass) according to the function. The single type is used for the single-fiber, and the mass type is used for the ribbon fiber. It is different in the reinforcement between two types. The single one realizes the reinforcement by the stainless steel needles, the later one via the ceramic reinforcement member to realize the function.Mass means there are several cores for the fiber. So the mass sleeve includes 4cores,6cores,8cores,12cores(for types).



  • Telecommunications subscriber loop
  • Fiber to the home (FTTH)
  • CATV

Operating Temperture Range

  • Operating temperature : -45°c~100°c / -45°c ~135°c
  • Minimum shrink temperature : 80°c
  • Minimum fully recovery temperature : 120°c


  • Consist of a Rod of rainforcing the splice, hot fusion tubing and cross linked Polyolefin. To rebuild the coating of fiber to provide mechnical strangth at the fusion joint area and keep the optical transmission properties.
  • Moisture resistant for environmental protecion clear sleeve make it easy to detect splice before shrinkage.
  • Easily use and avoid any damages to the oprical fiber during installation.
  • Sealing structure provides good performanc e to the splicing in the environment with temperature and humidity.
  • Bellcore GR-1380 Compliant 6. RoHS & REACH Compliant
