  • Fiber Optic Cable Sheath Material Inspection

    Fiber Optic Cable Sheath Material Inspection

    This part of the EN 50289 standard describes three methods for determining the UV resistance of sheath materials for electrical and fiber optic cables. These tests are valid for outdoor and indoor cable applications according to the product standard. Keep ambient or stray light from creating signal noise (for sensor applications). Glass fiber and plastic fiber is fragile. The primary reason for fiber inspection is to ensure that the connectors are free of any defects, damage, or debris that would prevent sufficient transmission of light when mated. There are three main principles that needs to be taken in consideration for an efficient optical connection: a perfect core alignment, perfect physical contact and dirt-free connectors. Fiber cable quality is evaluated across multiple dimensions: Each parameter requires a specific test method and acceptance threshold.
