Fibrain FB744x heat-shrink splice protection sleeves provide high protection during splicing process. They can be characterized by small outer diameter (even 2.4mm diameter after shrink), optimal length and fast installation. The heat-shrink sleeve is strengthened with a steel pin of 1 mm diameter and the same coefficient of heat expansion as optical fiber. It prevents from longitudinal stresses, which cause an increase of insertion and reflection loss.
Fibrain heat-shrink sleeves protect fibers against mechanical damages, pollution and weather conditions, and they do not cause any loss of optical power. The outer material guarantees sustainability and resistance to stretching and puncture. Excellent environmental parameters provides safe and stable usage in both indoor and outdoor installations.
Protection sleeves are available in two lengths:
