Technical Description The CFN 27 Port Connectorised M length closure is supplied with an IR foam entry block, a loop storage basket, IR Fibre Management system, connectorised tray and 3A splice trays. The base configuration of 26 round ports and 1 oval port covers a cable diameter range of 1.7 – 16.5mm when using Cablelok mechanical seals.

The mounting system is manufactured from glass filled nylon and is supplied with a single connectorised tray and 4 SC-B CFN 3A splice trays. The position of the mounting system allows easy access for the routing of fibre on to the trays and the basket provides storage space for the storage of fibre loops. The trays and fibre 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.

The fibre entry block has additional dedicated PLC splitter accommodation for a maximum of 2 x 250μm bare end PLC splitters and fibre management for fibre direction changes and storage of excess fibre. 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.

All IR system cover parts are coloured blue identifying them as removable parts allowing access to the fibre. The fibre slot retaining clips are coloured red to aid in identification if they are dropped.

The CFN Connectorised tray is manufactured from ABS and is fitted with 2 x PLC/3A splice protector inserts, 6 LC/APC quad adaptors and 3 x 1:8 bare end to LC/APC PLC splitters.

The CFN IR single element trays is manufactured from ABS and is fitted with 2 x 3A splice protector inserts which are positioned at the front of the tray providing a maximum splice capacity of 24 double stacked 3A (heatshrink) splice protectors up to 60mm long.
