The Integrated Routing (IR) fibre enclosure is manufactured from zinc passivated mild steel and stainless steel. The closure has a separate entry and exit point allowing access for a maximum of 4 cables, each with a maximum diameter of 20mm (when used with the optional cable bridge clamp) . The design of the closure provides support for up to 56 5mm blown fibre tubes when utilising the bottom cable entry point in conjunction with the optional IR duct manager and foam fibre manager. The closure compartment accommodates a maximum of 24 SC-IR or 12 SE-IR trays (or a combination of SC and SE trays). The fibre management system allows the installer to organise and configure the fibre prior to routing it on to the trays.
The modular design of the trays and the fibre optic routing module allow for the trays to be easily clipped into place. The system allows for easy routing of fibre on to the trays. The trays and fibre optic routing module are white which makes it easy to see the colour of the fibre elements as they are routed through the system. The fibre slot retaining blocks guide the fibre elements into the IR system, the foam pad on the retainer is partially cut through to accommodate a range of fibre counts, and the plug is keyed so that it can only be inserted in one direction.
All the IR system cover plates are coloured blue identifying them as removable parts allowing access to the fibre, the fibre slot retaining block and tray retaining clips are coloured red to aid in identification if they are dropped.
