Fibre Splice Protection Sleeves
$1.00
The fusion spliced region of the fibre is bare glass and thus needs to be protected. Various systems designs are used to carry this out.
The thermo shrinking type of splice protection sleeves consists of three parts, the outer heat shrinkable tubing, the inner hot melt adhesive tubing and the strength member. The inner hot melt adhesive melts and adheres to the fibre and the outer tubing shrinks to completely encapsulate it. The strength member gives mechanical strength to the sleeve preventing bending and allowing the sleeves to be arranged in splicing trays conveniently.
- Designed to restore complete environmental and mechanical integrity of coating or buffer of optical fibre after splicing.
- Sleeves are manufactured using state of the art machines and controlled manufacturing environment in an ISO 9001 certified manufacturing facility.
- Outer tube conforms to MIL-I 23053/5 class 2 standards.
- Hot melt adhesive tube made from polyolefin Ethyl Vinyl Acetate copolymer bonds both to the fibre and heat shrinkable outer tube to effectively encapsulate fusion splice.
- Strength member is made from “Full hard” stainless steel of SAE 316 grade and is ground at the edges before polishing to make it completely burr free to avoid rupturing during shrinking. 316 grade gives better corrosion resistance than 304 or equivalent grade, even in coastal environment.
- Resistant to heat shocks, no cracking dripping or flowing.
- Long term proven performance, exceeds industry standards with satisfied customers.
- Sleeves are preshrink which ensures integrity of assembly during transportation & reduces shrinking time thus increasing battery life of oven.
