Daetwyler Cables has added another time and money-saving solution to its portfolio of complete copper and fibre-optic technology solutions for data centres with the Break Out system (BO). The BO system is based on very compact multiple cables (trunks) with 12, 24 and 48 mini fibre-optic cables all contained within a single outer sheath. The mini FO cables are pre-assembled with LC connectors on both sides. Daetwyler supplies them with OM3 grade multimode fibres (G50/125μ) or OS2 grade single-mode fibres (E09/125μ), each of which is protected by aramide yarn and has its own sheath. With a diameter of 1.8mm each, even the BO multiple cables are very thin: the external diameter of trunks with 24 mini cables is only 1.1cm, that of trunks with 48 individual cables only 1.84cm. The latter can easily be terminated in a 1U height distribution panel. The pre-assembled BreakOut cables with LC connectors on both sides are just as easy to handle as pre-assembled copper patch cables. Customer-specific labelling on individual mini cables and on the common cable sheath facilitates simple documentation and the clear allocation of connections in the distribution panel. The use of “Panorama” building, technology and network management software means that cabling project documentation is available and usable even before installation starts. The optical distribution boxes supplied by Daetwyler for the BO system are OV-A models with exchangeable front plates, pre-assembled couplers (24 LCD) and two rear cable entries which can be either straight or angled. Because of the small diameter of the BO cable, the inputs and the strain relief in the distribution panel are provided by commercially available cable glands (M25). Cable dividers are entirely redundant in this FO cabling system. Thanks to two cable inputs, multiple groupings are also possible in the distribution panels, for example 24x OS2 and 24x OM3 to 1U. Excess fibre lengths of 1.5m in the box make for easy replacement of connectors during servicing. A time and money saving solution Money saving solution from Daetwyler m m
