PRO POWER Optical Fibre Fusion Splice Sleeves, Large Pin, 50 Pack - 45mm

The PRO POWER Optical Fibre Fusion Splice Sleeves are expertly engineered components designed to restore and maintain the critical environmental and mechanical integrity of optical fibre cables following the fusion splicing process. This 50-pack provides a reliable supply for telecommunications, data centre, and fibre optic network installation and repair work.

Each sleeve features a robust outer heat-shrink tube crafted from polyolefin (PO) material, which offers excellent durability and protection. At the core is a stainless steel rod, specifically designed for single-fibre splices. This rod ensures precise alignment of the spliced fibres and provides essential rigidity to the joint, preventing micro-bending and signal loss.

An internal adhesive liner is activated during the heating process, creating a complete and robust environmental seal. This adhesive bonds securely to both the optical fibre itself and the outer heat-shrinkable tube, effectively encapsulating the delicate fusion splice joint. This encapsulation shields the splice from moisture, dust, and other contaminants that could degrade performance over time.

A key advantage is the quick shrink-down time and straightforward installation procedure, which significantly reduces the risk of damaging the optical fibre during handling. The sleeves also provide effective vibration damping, further protecting the sensitive splice point from physical stress. The transparent colour of the shrink tubing allows for easy visual inspection of the splice alignment and adhesive flow after installation.

These large-pin splice sleeves are a fundamental part of creating reliable, long-lasting fibre optic connections. They are an indispensable tool for engineers and technicians aiming to achieve low insertion loss and high return loss splices that meet industry standards for performance and longevity in both indoor and outdoor applications.
