Engineering labels for optical fibers
These labels are affixed to optical fibers that connect the fiber ports on the cards in a chassis, or
connect fiber ports on box-type devices. There are two types of labels for optical fibers: labels for a
fiber that connects the fiber ports on two devices, labels for a fiber that connects the device and the
optical distribution frame (ODF).
