Which of the following order is correct about the internal tail fiber？ ()

①Insert the tail fiber between subracks in the related interface, and bind the extra optical fiber by the yellow adhesive tap, fixing it on the cable immobility board inside the routing area to the right of the rack after routing the fiber through the routing slot in subrack.

②Insert the tail fiber between subracks in the related interface, and fix the extra optical fiber in the fiber-coiling box on the right of the subrack after routing it through the wire-routing slot. When there is very few internal fiber, you can also put the fiber-coiling box on the left of the rack.

③Arrange the optical fiber neatly, and put optical fiber tag on it.

④Decide the wiring path of the optical fiber and put tag on it according to the position of the interfaces on both ends of the optical fiber.

⑤Adopt a sequence of bottom up and from left to right when connecting the optical fiber on the ODU and the OMU board, and the fiber connection order on the OTU board should be the same. When there are multiple OTU subracks on the ODU or the OMU board, first connect the optical fiber between subracks first, and then connect the optical fiber inside the subrack.
