Quick Start 01

This solution prevents the introduction of sudden heavy currents into the
network box, thereby protecting the device inside the network box
against heavy currents. (A long-distance armored optical cable may
introduce sudden heavy currents into the network box if the outer
insulation layer is broken and connects to a heavy-current power line.)
Solution 1 is implemented as follows:
i. Strip the outer insulation layer and armored tube from the fiber
strength member at the ground point. Then, clean bare optical fibers
and use a protection tube to protect them. (Use outdoor tubes in
outdoor scenarios and common tubes in indoor or corridor scenarios.
Use waterproof tape produced by 3M or COTRAN.)
ii. Use a piece of sandpaper to polish burrs at the stripped position of
the optical cable. Then, use insulation tape to wrap the stripped
optical cable. When wrapping the waterproof tape, ensure that fiber
cores are force-free.
iii. Cut excess fiber strength member for grounding.
