OFC Sleeves 40mm

The OFC Sleeves 40 mm are essential fiber optic accessories used to safeguard spliced fiber joints. Each sleeve contains a heat-shrink outer tube with an internal reinforcing rod that strengthens the splice point and prevents micro-bending losses. When heated, the sleeve shrinks tightly around the joint, forming a secure, moisture-resistant seal. Ideal for use in splice trays and closures, these 40 mm sleeves are compatible with both fusion and mechanical splicing methods, making them a standard choice for professional fiber installations and maintenance.
