Reinstall all these doors after installing and routing all cables and fibers. Refer to Chapter 12 "Installing the Doors of the Cabinet". This chapter guides you to install and route fiber jumpers. The fiber jumpers of the OptiX OSN 3500 are divided into internal fiber jumpers and external fiber jumpers. Internal fiber jumpers are used for connecting optical interfaces within a cabinet. While external fiber jumpers are used for connecting optical interfaces of a cabinet with those of other cabinets or peripherals.

In this section the corrugated pipe is taken as an example. Appropriate length of the corrugated pipe is required. This length is the distance from the cabinet to the ODF plus the length the pipe will extend into the cabinet and the ODF (so long as the fiber jumpers do not touch the upper beam when routing inside the cabinet). 10 0 This procedure guides you to connect and route the fiber jumpers between the subrack and the ODF. *23 Corrugated pipe or winding pipe Binding strap Labels 04 The ODF in the equipment room has been installed properly, with interfaces reserved for use. 42#  Required if the fiber jumpers are upward routed.
