FDN Dome Closure

The FDN fibre splice closure delivers fibre to individual buildings or properties. The FDN is an oval shaped fibre closure with a high drop count making it the ideal solution for built up areas where there are multiple buildings to service. 

The closure cover is environmentally sealed with a high quality clamp and ‘O’ ring. The cable ports can be sealed using either Cablelok mechanical seals or heatshrink sleeves. The closure can be fitted with a flash test valve and/or grounding feed through. For flash test valve and/or grounding feed through versions please contact our sales office.

The FDN has 4 base types: 

The 59 Port Base

• 58 round ports and 1 oval port
• Cable diameter range of 1.7 – 29.0mm when using Cablelok mechanical seals and 6.0 – 35.0mm when using heatshrink

The 16 Port Base  

• 15 round ports and 1 oval port covers a cable diameter range of 4.8 – 29.0mm when using Cablelok mechanical seals and 6.0 – 35.0mm when using heatshrink
• Moulded supports on the base allow the cover to be removed from the closure whilst it is still in-situ
• Bosses moulded in to the closure base enable fixing of external cable management attachments. 

The 29 Port Base

• 28 round ports and 1 oval port
• Cable diameter range of 10mm – 20.0mm when using Cablelok mechanical seals
• Integrated closure mounting points for MOBRA, pole and facade fixing

The 53 Port Base

• 52 round ports and 1 oval port
• Cable diameter range of 1.7mm – 20.0mm when using Cablelok mechanical seals
• Integrated closure mounting points for MOBRA, pole and facade fixing.

The Integrated Routing (IR) FDN closure has a modular fibre management system and is available in a range of lengths to suit the number of fibres and splices required. The IR system has been designed to ensure positive fibre management throughout the closure. The components ensure a 30mm bend radius can be maintained from cable entry all the way up onto the splice trays.
The IR system offers a number of configurations and splice tray options. Supplied in packs of 12 (SC Trays) or 6 (SE Trays), the trays can be easily installed onto the IR backplane. The splice trays can accommodate a number of splice types including 3A and ANT as well as a selection of fibre optic splitters.
The FDN IR closure has a maximum splice capacity of 864 fibres using either the SC-B tray with 3A/ANT splices or the SE tray with ANT splices.
 

• Accommodates up to
  • 36 SE MKI and MKII, 
  • 72 single circuit (SC and SC-B MKI and MKII) trays or a combination of both
• Fibre storage basket for loop through applications
• Positive fibre management to ensure consistent 30mm bend radii throughout
• Bi-directional fibre routing
• Splitter accommodation

The standard Tubed FDN closure from HellermannTyton is available in 4 different lengths, with a number of splice tray options. The tubed FDN closure can also be supplied with fibre storage baskets.

The tubed solution routes fibres from the entry point of the closure in transportation tubing directly onto the splice trays. The transportation tubing helps maintain bend radius whist adding good protection to the individual fibres.

The tubed FDN offers a number of configurations and splice tray options including standard Hellipse trays and the Multi-Ribbon tray. The splice trays can accommodate a number of splice types including 3A and ANT as well as a selection of fibre optic splitters.

The tubed FDN closure has a maximum splice capacity of 864 fibres using either the Hellipse SMF SE-A tray with 3A splices or the Hellipse NZDF SE-A tray with ANT splices.
