Where fibre is concerned it is crucial that the cabling has adequate support over longer runs while maintaining an optimum bend radius throughout .

It is essential that cable going into the rack maintains its optimum bend radius , without excessive pulling or stress on the cable . As soon as these are compromised , the performance of the entire network could be affected . However , by using patch panel with rear cable management , any unnecessary stress or strain on the cable can be alleviated . A rear cable management bar or a tray solution could be specified , with further protection offered by the use of a flexible conduit . It is also worth noting that front cable management within the rack with the use of bars and panels can also maintain the bend radius and aid cable and port identification .
The key to infrastructure design is maintaining the optimum bend radius throughout the network , supporting the weight of the cable wherever possible and keeping exposure to external elements such as dust and dirt to minimum with the use of lids and covers . Copper pre-terminated systems are often bundled together in a loom adding additional protection and rigidity to the cable . This can relieve a number of issues . Allowing the cable loom to be laid out in an overhead or underfloor cable tray provides for a neat and tidy network infrastructure .
When it comes to data centre design and infrastructure it is important to remember that one size doesn ’ t fit all . So it is vitally important that the right system , installation and cable management is chosen from the outset . Electrical contractors need to research the type , weight and amount of cables the system is required to carry , as well as the installation environment and the amount of space available , before making a decision . Contractors need to consider the context of the build , and develop a deep understanding of the installations environment .
