A closure fiber optic joint, a critical component in fiber optic networks to shield and tie its fibers together. When two or more fibers are spliced into a common point at such joints, the main function of the joint closure is merely to protect them from damage or dirt and to ensure data can still pass through without interruption. Principally found in Europe or Asia today It provides a reliable and seamlessly aligned splice for two fibers which can readily be connected with a reasonably small insertion loss. Built with precision machined components housed inside custom-made aluminum case as in all our products, it combines high mechanical strength with an inherent resistance to weathering and humidity. The product incorporates the latest semiconductor technology and skillfully designed Firmware, making it not only stable but also distinctly easy to manage and maintain. A closed-end cable or joint closure as it is known, for various applications ranging from telecommunication networks and data center to slag accumulation in fibre optic wires.
