A for Military Ships

August 2004

What is A?

• A is a system of:– tube assemblies– tube connectors – tube management closures– fibre bundles– fibre management closures– cable glands and cable ties– pigtails and patchcords– installation, calibration, verification and testing

equipment

What do A networks offer for network operation, repair and maintenance?

• A offers:

– Easy upgrade path for extension of the network or replacement of fibre bundle

• with no disruption to fire seals, cable runs, bulkheads and glands

• Fibre Bundles designed for maximum blow length, ease of handling and ruggedisation.

What do A networks offer for network design?

• A offers:

– Flexibility

– Ease of break and branch which allows blowing straight to panels and reduced numbers of panels

– Point to point fibre with low loss budget

– Designed to fit standard 19” rack configuration for all components

– Reduced weight and space requirements

Specifically Designed Break & Branch Boxes and Splice Boxes for BAE Projects

What features of A fibre bundles are relevant?

A fibre bundles can offer:

– 2,4,8 or 12 fibre bundles fully qualified for operating temperature range of -40 °C to +60°C

• G652 and G652c options

• 50/125, OM2 Multimode fibre based on Infinicor 600

What features of A fibre and tube management are relevant?

A, all components of the fibre and tube management system have – successfully undergone 70g shock testing in Rosyth

Naval Dockyard in February 2004 with continuous data streaming during shock

– space efficient and functional design

– been deployed on Type 45 destroyer

– pigtails and patchcords will be sheathed with the same material as tube assemblies.
