2.1 Regulations for Routing and Bundling the Indoor CableIn actual situations, you must strictly observe the regulations when routing and bundling theindoor cable.

2.1.1 CablingWhen routing cables, ensure that signals are transmitted reliably, and also ensure that futuremaintenance is easy.

2.1.2 BundlingCables must be tightly bundled. The bundled cables should be neatly arranged.

2.1.3 Bundling Fiber JumpersUse a special binding strap to bundle fiber jumpers.

2.1.1 Cabling When routing cables, ensure that signals are transmitted reliably, and also ensure that futuremaintenance is easy.

The cabling requirements are as follows:

l Signal cables should be routed separately from power cables, fiber jumpers, and jumpers.

l The specifications and cross-sectional area of the cable, and the route and position for thecabling should be designed beforehand. All the cables should be arranged neatly.

l Cable turns should be smooth. The bending radius of cable turns should be larger than 60mm, and the bending radius of fiber turns should be larger than 40 mm.

l There should be no damage to the insulating layer of the conducting wire.l Cables that are routed along the wiring frame must be bundled.

They should be bundled closely with appropriate tightness. The spacing between cable tiesshould be even.

l Cables in troughs do not need to be bundled. They should be placed neatly and in a straightmanner without any crossover. The cables should not protrude from the trough. The cablesshould be bundled with cable ties at the inlets, outlets, and at the turns of the trough.

l IDU cables should be routed along the left and the right to facilitate operations, and shouldnot cover the board indicators.

In other words, the cables of the boards in the left slots should be routed to the left of thecabinet and those in the right slots should be routed to the right of the cabinet.

l Leave enough slack when connecting cables to the IDU to facilitate insertion and removalof the boards and the fan box. If the IDU is equipped with a fan box, the cables of the IDUhave enough slack so that they can be routed away from the front of the fan box.

2.1.2 Bundling Cables must be tightly bundled. The bundled cables should be neatly arranged.

The bundling requirements are as follows:

l Do not b ind the power cable with other types of cables.

l The cab les should be bundled neatly.

l Use cable ties of different specifications according to actual circumstances.

l Do not connect two or more cable ties and use them as one to bundle cables in case thetightness is reduced.

l After the cable ties are fixed, the extra part of the cable ties should be trimmed such thatno burrs exist.

l The spacing between the cable ties should be even and should be three or four times thediameter of the bundle.

l When making turns for bundled cables, ensure that the bending radius is as large as possibleso that the cable cores do not break.

2.1.3 Bundling Fiber JumpersUse a special binding strap to bundle fiber jumpers.

Observe the following requirements when bundling fiber jumpers:

l Arrange fiber jumpers tidily into a bundle before bundling them.

l Ensure that the mat side, and not the hook side, of the binding strap is in contact with thefiber jumpers.

l Bundle fiber jumpers with appropriate tightness. Do not bind them too tightly.

l The spacing between two binding straps should not exceed 40 cm.

l Do not bundle too many fiber jumpers together.

In the case of the 2 mm fiber jumpers, a maximum of 100 pieces can be bound together. Inthe case of the 3 mm fiber jumpers, a maximum of 60 pieces can be bound together. If thereare a large number of fiber jumpers, bind them into several bundles.

2.2 Routing and Bundling the IF CableIn actual situations, you must strictly observe the regulations when routing and bundling the IFcable.

The routing requirements are as follows:l The IF cable should be routed from top downwards and should be bound at the time of

routing.l The specifications and cross-sectional area of the cable, and the route and position for the

cabling should be decided beforehand. The cable should be arranged neatly without anyoverlapping or crossover.

l The IF cable should be curved for waterproof consideration under the ODU and beforeentering the IDU room.

l The bending radius of the IF cable should be larger than 30 cm.

The bundling requirements are as follows:

l The IF cable routed along the wiring frame must be bundled. Whether to use binding tapesor cable clamps to fix the IF cable depends on the actual situations. It should be closely

bundled with appropriate tightness. The spacing between the cable ties for outdoor use (thecable ties for outdoor use are in black) should be even.

l The IF cable should be bound by using the cable ties for outdoor use every one meter.

l The cable ties for outdoor use should face the same direction. There should be a slack of 3mm to 5 mm before cutting the cable ties.
