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. The following two types of labels are used for optical fibers:
• Labels for a fiber that connects the fiber ports on two devices
Table 86 Information on labels affixed to the fiber between 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
