Last Friday, Sumitomo Electric Lightwave (SEL) introduced 12- and 2-fibre ribbon bundles designed for its Future Flex Air Blown Fibre to the Desk (FutureFlex TTD) system.
According to SEL Vice President Fred McDuffee, these lightweight ABF bundles, available in 62.5 and 50 micron multimode and singlemode configurations, facilitate extending fibre to the desk or other workplace applications using either zone or CNA (centralised network architecture) topologies.
In the zone configuration, 12-fibre ribbon bundles configured as 3, 4-fibre ribbons encased in a special sheath can be blown in a splice- and stress-free run from the computer room to fibre termination units (FTUs) serving workstation clusters. From these FTUs, SEL fibre harnesses or duplex patch cords provide connectivity to workstation wall plates.
In the CNA configuration, ABF tubing routed to each workstation provides the path to blow 2-fibre ABF ribbon bundles similarly encased in a special sheath directly to workstation wall plates from the nearest FutureFlex Air Blown Fibre System tube distribution unit (TDU). TDUs can be located in the ceiling, a raised floor or a wiring closet and function as branching for tube pathways.
To complement its new FutureFlex TTD system, SEL is also providing a family of fibre connector products. These include a field-installable 12-fibre ribbon MPO connector.
Sumitomo’s FutureFlex Air Blown Fiber System employs compressed air to blow lightweight optical fibre bundles containing up to 18 fibres through multi-celled tube cables at speeds to 150 feet per minute. Moves, adds and changes are quickly accommodated by blowing out old fibre and blowing in new.
There is no need to install ‘dark’ fibre in anticipation of future requirements. Additions or reconfigurations can be accommodated fast and usually only with a crew of two.
