Application
The UCAO Closure (Universal Closure Access for Optical Cables) provides environmentally protected sealing on splices of fibre optic cables. In addition, the UCAO Closure provides excellent cable strain relief and space for excess buffer tube storage. It can be installed with all common cable sheaths and is suitable for buried, duct and aerial applications. Due to its compact design, the UCAO Closure is ideal for the connection of low to medium distribution cables. The ease of opening and closing makes this inline closure ideal for access networks.

Design
The body of the UCAO Closure consists of two half shells made of plastic that is resistant against all environmental influences. The intersection of the half shells is sealed with a reusable silicone ring. The UCAO Closure has an integral hinge on one side and five stainless steel and plastic tensioners on the other side. The tensioners can be closed by hand and easily opened with a screwdriver. To prevent unauthorized access, an anti-access device option can be installed on the clips. The two cable entries on each endface of the UCAO Closure can accommodate cables with outer diameters of up to 21 mm. The cable entries are placed between the cable entry wedges in the lower half shell.With a four-cable entry set, including multiple strain relief and a filling piece, each cable entry can be adapted to fit four cables of up to 8 mm in diameter. Alternatively, a closure with sealing wedges, each containing one port with compression fittings, is available. These ports simplify the installation of branching cables in the event of future demand. Both the cable sheath and the central members are strainrelieved with clamps locked into the lower half shell. The same clamps provide an electrical connection and external grounding if required. The tightness of the closure can be flash-tested by using the optional tightness testing set.
