Prysmian XMJ Pre-Connectorised Closure
The pre-connectorised XMJ closure range (CMJ/MMJ) is designed for jointing optical fibre cables. The joint is ideal for use as a final drop solution due to its capacity and compact size.
It has a maximum capacity of 72 fibre splices (MMJ). The connectorised pigtails are factory fitted and each tray can accommodate up to 12 spliced fibres.
The single element 2.2 tray also has the ability to house up to 1x1:8 splitter, which can also be factory fitted.
A multi-functional bracket can be supplied with the joint which enables wall or pole mounting of the joint vertically or horizontally.
The joint has four circular ports for mechanical entry glands, one oval port for heat shrink or mechanical entry and two additional small circular ports also for heat shrink entry.
Design and Construction
• Supplied with up to 2 (CMJ) / 6 (MMJ) single element trays each able to accommodate 12 splices providing a maximum capacity of 24 (CMJ) 72 (MMJ) fibres.
• Drop cable capacity 12SC / 24LC (CMJ) 24SC / 48LC (MMJ)* MMJ closure cannot support 48 individual drop cables. Multifibre drops should be used to utilise the full capacity.
• Each tray has the provision to mount optical splitters.
• The closure base has 4 circular entry ports and an oval port. Cables up to 23mm in diameter can be installed into each port.
• Drop cables are installed through a split seal and routed around the input mandrels
• A further two small ports are available as emergency ports. These ports are for heat shrink entry and can
accommodate a cable of up to 12mm in diameter.
• Circular port cables are sealed using a split mechanical sealing gland.
• Oval port cables are sealed using adhesive lined heat shrink sleeves or using a mechanical oval port entry
kit.
• Multi Way Split Entry Glands are available to allow the installation of a number of cables into one circular port.
• Splice trays hinge upwards individually, allowing full access to spliced fibres without disturbance to live fibres in adjacent trays.
• Integrated loop storage basket for mid-span applications.
• Can be supplied with a pole/wall mounting bracket.
• Can be supplied with a flash test valve or a pressure relief valve. These can also be used for earthing
• Closure and glands sealed to IP68.
Technical Data
• Minimum Fibre Bend Radius (mm): 30 (Note: The input manifold contains mandrels to cross fibres from one side of the stack to the other. These are limited to 20mm radius if used).
