The general description of cable (including ground wire, power cable, network cable, mini SAS cable, and serial port cable) and optical fiber layout can effectively guide you to master the overall wiring principle and avoid unnecessary losses caused by wrong wiring.
General principle of cable laying
In a room with brackets and anti-static floors, cables can be routed down the line, and all cables can be routed through the floor mezzanine or walkway. If you use up-wire, you need to lay the walk-through rack at the top of the cabinet, and the cable is routed through the walk-through rack.
The specifications, routes, sections and positions of the cables should be pre-designed and the cables must be arranged in a neat arrangement.
Do not damage the cable insulation.
Cable turns should be uniform and smooth, and the minimum bending radius of cable turns should be greater than 60mm.
Cables should be clothed for easy maintenance and future expansion.
It is recommended that strong wire cables (power cords and ground wires) be separated from the signal cables and spaced by more than 30mm, and between power cords and ground wires separately and at a distance greater than 150mm to reduce electromagnetic interference.
General principle of optical fiber placement
When the fiber is put on, there should be no strong pull hard pull and unnatural bends.
When the fiber is put on, the bending radius of the fiber must not be less than 50mm.
No other cables should be pressed against the fiber after the fabric is put.
When installing in the cabinet, the fiber should be fitted into the bellows. The bellows should reach into the cabinet about 100mm.
In hardware installation, the shipped bellows need to be cut off according to the actual length used. After cutting the bellows cut is relatively sharp, easy to wear fiber, so it is necessary to tape the intestion of the bellows, so as not to wear fiber.
In the room where brackets and anti-static floors are installed, optical fibers are routed down the line under the protection of bellows, all of which are routed through the floor mezzanine or the walkway.
When using the upper line, it is required to lay the carrier above the cabinet, and the fiber is protected by the bellows through the walk frame at the top of the cabinet.
If the distance between the carrier and the top of the cabinet is greater than 0.8 meters, a line ladder should be set up above the cabinet.
