Remove the side doors and the front door before installing and routing cables.
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.

When routing fiber jumpers outside the cabinet, a corrugated pipe or a winding
pipe must be added for protecting the fiber jumpers.
One corrugated pipe can contain 12–15 pieces of fiber jumpers. One 12 mm
winding pipe can wind thirty pieces of fiber jumpers, while one 6 mm winding

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).

This section guides you to install and route internal fiber jumpers. Internal fiber
jumpers are used to connect boards in a subrack or connect the boards with other
devices (COA, for example) in the cabinet.
Internal fiber jumpers can be routed:

Between optical interface boards in the subrack. In this case, the fiber spool
box is installed above the subrack.

Between the subrack and other devices (for example, SS62COA) in the
cabinet. In this case, the fiber spool box is installed below the subrack and
above the COA.
For details of the fiber spool box, refer to Chapter 8 "Installing the Fiber Spool
Box". For details of the COA, refer to Chapter 7 "Installing the COA and DCM"


All fiber jumpers are nicely bundled in even spacing with appropriate
tightness.

Fiber jumpers can be moved freely in the cable tie.

Fiber jumpers routed from the equipment to the ODF must be covered with a
protective pipe. Both ends of the protective pipe shall extend into the
equipment or the ODF.

In routing, the fiber jumpers shall not be pulled or dragged with great force or
bent forcibly.

Fiber jumpers are routed in a way convenient for maintenance and capacity
expansion.


Routing of the fiber jumpers complies with the engineering design.

The fiber jumpers are secured smoothly and interconnected reliably in the
ODF. The redundant fiber jumpers are coiled tidily.

There shall be no other cable or article on the fiber jumpers.
