Demarcation Dome Closures

Demarcation Dome Closures

Optotec’s FOCUS DOC (demarcation optical closure) and CDOC (compact demarcation optical closure) range of fibre optic closures. Environmentally sealed with modular cassette management system enabling splicing, patching and passive optical component integration in external fibre optic networks. Available in component form or kitted for specific customer requirements.

The FOCUS DOC and CDOC range are a butt cable entry design with various dome lengths and base configurations to ensure a solution to current network requirements can be readily accommodated. Closures can be deployed underground in man-holes, hand-holes or in pole-mount, wall and aerial applications and are available with pressure valve and grounding kit if required. Please refer to the product page Closure Mounting Accessories for further details on the various mounting accessories available.

FOCUS DOC closures are available in one base style; ‘A’ with single oval port and 6 round ports and two dome height lengths. ‘A’ dome with total height of 390mm (DOC), 380mm (CDOC) or ‘B’ (DOC) dome with total height 525mm. ‘A’ bases can accommodate heat-shrink and cold sealing. Please see Heat Shrink Sealing Kits, Cold Seal Kits for further details on the various sealing kit configurations available.

Each demarcation closure has both splicing and patching capability. Fibre splicing and management is undertaken with Optotec’s SAM (Splice Array Module) system accommodating various splice capacities and supports either heat-shrink or crimp style splice protection. Patching is done at the rear of the splice array modules and supports either SC or LC connectivity in varying densities depending upon the closure.
