Technical Description The FDN 59 Port Integrated Routing (IR) AB Length closure is supplied with a Polypropylene base. The base configuration of 58 round ports and 1 oval port covers a cable diameter range of 1.7 – 29.0mm when using Cablelok mechanical seals and 6.0 – 35.0mm when using heatshrink. The mounting system is manufactured from Grade 304 stainless steel and the backplane is an aluminium extrusion which manages 24 x SC-IR MKI moulded splice holder trays. The position of the mounting system allows easy access for the routing of the 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 positive fibre management system. Fibre slot retaining blocks guide fibre elements in to the IR system, the foam pad on the retainer is partially cut through to accommodate a range of fibre counts.
All 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.
