External Fibre Closures

Providing safe and efficient connections and storage of optical fibres in the outside plant

Whatever the size or configuration of your network, it’s vital to protect your organisation’s connectivity. Fibre optic closures (often referred to as fibre optic splicing closures) connect and store optical fibres safely in the outside plant, protecting them from the harsh environment.

Prysmian has a comprehensive portfolio of joints to manage the splicing and distribution of optical fibres throughout the network in both point-to-point and passive optical network (PON) environments. Our products include Optical Fibre Closures of various sizes as well as Connectorised Block Terminals (CBT)
