19 August 2003 Swindon, UK -- DÃ¤twyler Cables+Systems has launched the Quick Branch And Connect (QBAC) Indoor, a system for Fibre To The Desk cabling.
The modular system consists of a durable, flame-resistant QBAC mini tube cable, 19in patch panels in 1 and 2 height units, outlets for trunking and floor-mounted distribution points, branch connection splitters, as well as E2000 and SC duplex fibre optic adapters.
The dry construction of the cable allows for flexible fibre management, reduces the cable preparation and installation time by around 50% and, compared to other FTTD solutions the company says, significantly reduces the total costs.
The QBAC Indoor system allows 1Gbit/s data connections over a distance of up to 750m and complement Optoversal fibre optic cables for backbone applications. With OM3 category fibres, the Optoversal cables support 10 Gigabit Ethernet up to 300m.
The QBAC cable is easy to install says DÃ¤twyler. Rip cords and a specially designed central tube allow it to be opened at any point by simple twisting and thumb pressure. The system can also be extended easily as the mini tubes can easily be opened by hand.
There are two versions of the new FTTD system with 12 mini bundles each: the QBAC Indoor 12x4 G50/125 has 48 fibres, the QBAC Indoor 12x8 G50/125 has 96 fibres. With a small cable diameter of only 11.8 and 13-mm respectively, the space needed for cable routings and breakthroughs is minimal.
Thanks to their glass fibre strength members the cables can withstand pulling forces of up to 1000-N without damage and have a continuous crush resistance of 100-N/cm. Both models have a halogen free, flame-resistant coating preventing rapid fire spread and causing minimum smoke. At only 668 and 790-kWh/km respectively, fire load is also low.
DÃ¤twyler, which offers one day product training sessions, says that planning times can be significantly reduced compared to common FTTD solutions.
