The Fiber Closure accommodate cables of varying sizes and provide flexibility to add ports with the cable addition kit. The Cable Addition Kits 4- and 6-Port Grommets make system expansion even easier. A flexible tray system allows positionable or fixed splice inserts. Technicians can re-enter and swap out splice holders, and mix and match splice types (fusion and mechanical). The same tray can be used for discrete or mass splicing.All of these features combine to give you an enhanced ability  to offer optimum bandwidth for triple play services of voice, data and video. Upon delivery, all cable entries are fitted with blanking plugs. A wide range of cable entry flanges are available in various sizes. The individual cable entries serve to relieve strain being exerted on cables on the one hand and ensure an optimal seal without damaging the fibre-optic cables on the other. When installing additional cables in the splice closures, splice trays and cable entries can also be installed afterwards and without any special tools. This means that it is possible to change or replace a cable at any time. The cables can be prepared and sealed outside of the splice closure and before installation. This means that the work carried out within the splice closure in direct proximity to pre-installed fibres and thus the possibilities of error are reduced. The splice closures have a modular structure, are available in four sizes and offer the highest degree of protection. The robust housing is made from black shock-resistant plastic and ensures easy installation. The integrated pressure value allows overpressure to be generated inside the sleeve depending on its use. This keeps out dirt efficiently and also protects the housing from pressure applied from the outside.
