When network or optical cables are installed in a building or cabinet, the task of fitting cables into an organized bundle is called ‘cable dressing’. This dressed bundle is called a ‘loom’. A dressed loom of cables is typically a bundle of cables with the outermost cables – that is, the visible cables made to look neat and organized with cable lengths running parallel to one another.
Cables in close proximity to each other, especially those oriented in parallel or in loops, can create electromagnetic interference (EMI) through induction. EMI can result in erratic or error-prone data transfers. To minimize the effects of EMI, power cables should be segregated from data cables as much as possible:
- Dress all signal cables on the left side of the rack and all power cables on the right side of the rack.
- Arrange and secure excess power and data cabling separately.
Rack Dressing is of 3 types:
- Back Dressing (Left).
- Back Dressing (Right).
- Jack Panel Dressing.
