Overview
- Mechanical support - protection of fibre optic cable.
- Flexibility - Flexibility in network design where closures can be spliced in controlled conditions and then mounted in secure locations in the outside plant network, for example underground and aerially.
- Durability - Plastic bracket (UV stabilized ASA) material gives optimum durability in harsh environments
- Prevention of microbends within the fibre optic cable: Dexgreen bracket complies with bend radii of all fibre optic cables, this prevents degradation of system performance.
- Maintenance / Repair - By storing slack cable, carriers do not have to buy additional cable and splice it for emergency maintenance repairs.
- Compact - Lightweight and compact design, which replaces the need for more expensive storage units such as pedestals, vaults, cabinets. Ultimately – this reduces operational costs. Furthermore, the minimal use of pole space gives carriers to flexibility to make future expansions to the network.
- Unique Features – multiple drop cable management. Other customisations can be made if required
- Pole-mounted - bracket can be mounted directly on to poles (wooden / metal / concrete / plastic) through bolts / coach screws / steel banding
- Universal Closure Backplate Adapter: The Slack Management Brackets can accommodate multiple vendors’ fibre optic splice closures through a versatile backplate that can be simply attached to the bracket and secured into position using lockpins. This backplate adapter can also be installed within manholes for closure mounting.
- Splice Closures - Cable slack enables jointers to splice fibre within fibre optic splice closures at ground levels in controlled conditions and then ultimately mounting the closure on the bracket on an aerial telecom pole once complete. All splice closures are compatible simply by modifying the backplate. ????????
Material
Specification Acrylonitrile Styrene Acrylate (ASA) Similar to ABS but with better weather resistance ASA is stable against UV light and thermal ageing. This is validated by extensive testing performed by Dexgreen. In comparison to ASA, PC/ABS or ABS show a decrease of mechanical properties and change colour after a relatively short time. This embrittlement and yellowing is caused in particular by the UV part of sunlight combined with atmospheric oxygen. The butadiene rubber component of ABS and PC/ABS is very sensitive to UV radiation and heat: the chemical double bonds break down and the original properties are lost. Refer to charts below.
