As a telecommunications expert I'm often asked about these green boxes – technically called Street Cabinets or Cross-Connection Cabinets (CCC). Underground vaults or enclosures are used in all fiber optic networks that use GPON networks for FTTH or Fiber To The Home Deployments that are private or federal funded. They're essentially distribution hubs that house important electronic equipment splitters and connections that help deliver essential communication. A fiber optic junction box, also known as a fiber optic distribution box or termination box, is a protective enclosure that facilitates the connection and management of fiber optic cables. The main ones are Flowerpots, Brooks Boxes and Handholes. FTTH cabinets, therefore, house and protect optical fibre links in an FTTH network. They shield the indoor fiber optic.
