Modern telecommunications infrastructure relies on something as seemingly innocuous as the underground fiber optic junction box. Its main purpose is to connect, protect, and manage the fiber optic cables that carry so much information. It has many advanced features: it can use routing tables against congestion points to substitute around them; it even has thermal management systems in order to keep from overheating. Integrated monitoring equipment makes diagnosis and performance evaluation of the network easier by putting everything at your fingertips. At last the exterior of these junction boxes has been carefully designed to make them as resilient as possible: the waterproof and corrosion-resistant materials will allow each box to last for many years. Providing reliable high-speed connectivity, their applications are varied spanning various industries ranging from telecommunications and internet service providers to data centers and smart city initiatives.
