Huawei AP4050DN-E - Engineering Labels for Optical Fibers; Labels for the Optical Fibers Connecting Devices

5.4.2 Engineering Labels for Optical Fibers
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 One is for the fiber that connects the optical interfaces on two devices.
l The other is for the fiber that connects the device and the ODF.
