These labels are axed to the optical bers 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:
● One is for the ber that connects the optical interfaces on two devices.
● The other is for the ber that connects the device and the ODF.
