Introduction to Fiber Splice Closure
A fiber splice closure, also known as a splice case, is a crucial component in fiber optic networks. It is designed to protect fiber optic splices from environmental factors such as moisture, dust, UV radiation, and mechanical stress. These closures house the splice joints of optical fibers, ensuring the long – term reliability and stability of the optical signal transmission. They come in various types, including dome – shaped, in – line, and pedestal closures, and can accommodate different numbers of fiber splices depending on the network’s requirements.
