Connecting Procedure for HDOS Fiber
Optic Cables
General
Fiber jumpers must be single mode with ST

type connectors at the HDOS
Optical Unit (OU) end. The other end’s connector must match the connector of the
vendor’s fiber cross-connect panel.
Use care when routing the fiber cable in order not to pinch or severely bend the
cable especially when routing in the left duct. Route the fiber in accordance with
Figure 3-47 and the instructions below.
NOTE
:
The minimum bending radius of the fiber cable is two inches (four inches
diameter).
Fiber cables should be run apart from other cables in a separate protected duct.
Connections
Step 1:
Label both ends of the fiber cables in accordance with their associated
OU position, i.e. 1/2, 9/10, etc.
Step 2:
Remove the protective rubber cap from the assigned position at the rear
of the HDOS and connect one end of the optical fiber jumper cable.
Step 3:
Route the fiber cable over the ribbed cage to the bottom of the shelf and
then into one of the eight plastic troughs associated with the set of four
OU positions (J1-J4, J6-J9, through J36-J39).
Step 4:
Bring the fiber cable to the left cable duct (as viewed from the front) by
way of the other plastic duct located at the bottom and running the width
of the shelf.
Step 5:
Route these fiber cables to share the same fiber duct as the ARM Shelf
fiber cables.
