If using the shielded cable, ensure that the shielded layer well contacts with the
metal shell of the router at the router interface. We should install the signal arrester
at the corresponding interface of the router after the cable enters the indoor.
When the outdoor cable without any protection is connected to the router, we
should install the signal arrester at the corresponding interface.
When laying the fibers, it is required that the wiring is smooth and the bundling is
neat. It is required that the internal core wire is grounded before the outdoor fiber
enters the indoor. The fiber cannot be stretched or bundled too tightly.
D2.2 Installation Method of Cable Wiring
Installation Method of Power Cable
One end of the power cable is connected to the router and the other end is connected
to the power strip or lightning protection bar. The excessive part is folded to the shape
of S and fixed in the chassis. Keep a distance of more than 20cm with other cables.
Installation Method of Cables
The signal cables should be installed and bundled by indoor and outdoor, drawn from
the outlet holes of different chassis to the user terminal or cascading router.
Precautions for Using Fiber
When using the fiber to connect the network router, first confirm whether the type of
the optical connector and the fiber type conform to the used optical port type.
Before connecting the fiber, first confirm that the optical power of the receiving end
does not exceed the upper threshold of the receiving optical power of the optical
module. Otherwise, it may burn the optical module.
If the optical interface is not connected to the optical connector, please be sure to
wear a dust cap.
If the optical interface is not connected to the optical connector and the dust cap is
opened, maybe some invisible rays emitted from the optical interface, so you do not
directly look at the optical interface.
The fiber connector should have the safe and reliable packaging and the connector
should wear the dust cap. When not using, the fiber connector should wear the dust
cap, avoiding scratching the insert core of the fiber connector, and affecting the
performance index. If the dust cap is too loose or polluted, change it in time.
Before connection, we should use the dust-free paper to soak the anhydrous
alcohol and wipe the insert core of the fiber connector. You can wipe in one direction
