Draka proposes cost efficient approach to 10 Gigabit Ethernet network migration
Draka Communications has revealed that its current range of FTP cabling solutions now provide an off-the-shelf solution to the current industry challenge of cable packing density in fast emerging 10 Gigabit Ethernet projects.
The company is proposing a new cost efficient approach using shielded cabling systems providing security and space saving advantages when run within widely used three compartment containment cabling migrating to super speed data traffic.
‘As there is little price difference from their non-shielded counterparts, FTP cabling systems are coming into their own for high speed data networks’, said Lee Stokes, connectivity business manager, Datacom, Draka Communications. ‘They perform at Category 6A level, provide the highest headroom and remove concerns about Alien-NEXT. The latest slim generation of FTP cables has shielding that protects inner electronic circuits against all kinds of interference, including NEXT from the cable in the adjacent duct.’
Crosstalk is now high up on the agenda for cable management when moving to 10 Gigabit Ethernet and higher speed networks. A study commissioned last year by Draka demonstrated that for high end data centres, S/FTP cables offer the most secure option for data traffic integrity. The research results qualify FTP as highly recommended in protecting 10 Gigabit Ethernet traffic.
Shielded cables are mistakenly perceived as thicker and harder to work with – wrongly, as unshielded cables are often extremely rigid due to their thicker jacket. This is why, as well as EMC radiation, space is become a critical factor extending beyond modern small footprint data centre backbones to the thousands of office installations needing to cope with increasing service demands from data hungry users.
Networks upgrading to 10 Gigabit Ethernet are still the backbone of everyday office buildings which have their own defined cableways. In UK office environments data installers deploying three duct containment installations are dealing with cable management issues on a daily basis. Electricians run their electrical power through the larger middle compartment for electrical power, usually taking up two cables. Data cable installers are left with the smaller top and bottom compartments, which for non-shielded cable designs can result in additional costs for containment drops from a cable basket above a false ceiling in order to create additional space.
Correct cable screening eliminates the need for the space wasting separation of UTP cables, which often results in larger bundles in the cable channels. So shielding indirectly contributes to lower overall installation costs, including containment systems, while providing significantly increased headroom to AXT, as well as a greater degree of overall noise immunity. Yet another factor is that for 10 Gigabit Ethernet networks using UTP cables within three compartment containment systems cautious IT management will insist on having the three compartment separators shielded, which results in additional costs.
Current Draka cable designs offer a 10 per cent less diameter advantage over many UTP designs, together with the additional security of shielding to accomodate the most up to date 10 Gigabit Ethernet applications.
