    Adapter Dust Caps, Sleeves

    Dust caps are protective covers placed over the end of fiber optic connectors or adapters when they are not in use. They prevent contamination from dust, dirt, or other particles that could scratch or degrade the delicate fiber endface, leading to signal loss or poor performance. Made from plastic or rubber, dust caps are a simple yet critical accessory for maintaining the integrity of fiber optic connections during storage, shipping, or installation.

    Sleeves, often referred to as alignment sleeves, are cylindrical components within fiber optic adapters that precisely align the ferrules of two connectors. Typically made from ceramic, metal, or plastic, they ensure the optical fibers are perfectly centered to minimize insertion loss. The quality and material of the sleeve play a significant role in the adapter’s performance and durability.
