The HighSTACK™ series is a purpose-built range of high-density fixed enclosures designed for high performance carrier and data centre networks. By utilising a rigid, non-moving chassis, the HighSTACK™ platform provides absolute stability for high-count fibre links, eliminating the risk of macro-bends or connector stress often associated with sliding trays in high-density environments.
Available in 1RU, 2RU and 4RU configurations, these housings are pre-populated with shuttered LC Quadplex adapters to support up to 576 fibres in a single 4RU footprint. The internal architecture is optimized for mass-fusion splicing, featuring dedicated mounting points for ScaleFibre ribbon splice cassettes to ensure clean transitions from SmartRIBBON™ backbones to high-density patch fields.
Every HighSTACK™ enclosure features the AnchorLINK™ clip system for tool-less cable securement. These clips allow incoming cables to be snapped into the rear or side entry points instantly, providing superior strain relief and bend radius control without the need for traditional glands or cable ties.
