c) All fasteners should be firmly and reliably connected, and the sealing strip of the box should be flat and firmly bonded.
d) The opening angle of the box door shall not be less than 180o, and the opening and closing of the door lock shall be flexible and reliable.
e) When introducing optical cables, their bending radius should be greater than 15 times the diameter of the cable.
f) When fiber optic cables are laid inside the box, regardless of where they turn, their curvature radius should not be less than 30mm.
g) The minimum bending radius after fixing the butterfly shaped fiber optic cable should not be less than 10mm, and the reserved length inside the box should not be less than 0.5m.
h) The optical splitter installed inside the optical splitter box should be fixed inside the box with sturdy materials, and the performance indicators of the optical splitter must meet the requirements of the bidding technical specifications.
