A.5.2 Engineering Labels for Optical Fibers
This section describes the engineering labels for optical fibers, including the labels for the
optical fibers between devices and the labels for the optical fibers between a device and an
ODF.
These labels are affixed to the optical fibers that connect the optical interfaces on the boards
in a chassis or on the device boxes. There are two types of labels for optical cables:
l
Label for the fiber that connects the optical interfaces on two devices
l
Label for the fiber that connects the device and the ODF
