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).
• Labels for the fiber that connects two devices

Content Meaning Example
MN-B-C-D-R/T
MN—Rack number
• M—Row number of the rack in the equipment
room, in the range of A to Z.
• N—Column number of the rack in the
equipment room, in the range of 01 to 99.
For example, A01.
B—Chassis number
Numbered in top-down order with two digits, for
example, 01
C—Slot number
Numbered in top-down and left-right order with
two digits, for example, 01.
D—Fiber port number
Numbered in top-down and left-right order with
two digits, for example, 05.
R—Optical receiving interface
T—Optical transmitting interface
N/A
MN-B-C-D-R/T
MN—Rack number
The meanings are the same as above. If the local
device and the peer device are not in the same
equipment room, MN can be the name of the
equipment room.
B—Chassis number
C—Slot number
D—Fiber port number
R—Optical receiving interface
T—Optical transmitting interface
