Heat Shrinkable φ4 20mm Fiber Splice Protector
Heat Shrinkable Splice Protector 20mm φ4 Without Steel Strength Member
Brief Introduction:
Optical fiber heat shrink tubes consist of a rod of reinforcing the splice, hot fusion tubing, and cross-linked polyolefin. To rebuild the coating of fiber to provide mechanical strength at the fusion joint area and keep optical transmission properties. A specially designed cross-linked Clear Heat Shrinkable tubing, with Clear fusion tubing liner, providing protection to fiber optical splices. Available with single fiber and ribbon fiber. Customized designs are available upon request.
Fiber Splice Heat Shrink Characteristics:
- specially designed by the cross-linked polyolefin, hot melt tube and enhanced stainless steel wire/ceramic / quartz optical fiber splice protection devices, does not affect the fiber-optic light guide features
- protect splices and improve the mechanical strength
- simple operation, reduce the risk of damage fiber installation
- transparent casing, optical fiber splice clearly visible
- sealing structure to continue to have good resistance to temperature, humidity performance
- use of imported 304 steel, high-quality heat shrink tubing
- Operating Temperature: -55 – 100 ℃
- Shrink temperature range: 120℃
