Engineering Labels for Optical Fibers
- One is for the fiber that connects the optical interfaces on two devices.
- The other is for the fiber that connects the device and the ODF.
Labels for the Optical Fibers Connecting Devices
Meaning of the Label

Meaning |
Example |
|---|---|---|
MN-B-C-D-R/T |
MN: cabinet number |
M: The cabinet rows from front to back are numbered from A to Z. N: The cabinet columns from left to right are numbered from 01 to 99. For example, A01 is the cabinet in row A and column 01. |
B: chassis number |
Numbered in bottom-up order with two digits, for example, 01. |
|
C: physical slot number |
Numbered in top-down and left-right order starting from 01. For example, 01 is the first slot at the top left of the chassis. |
|
D: optical interface number. |
Numbered in top-down and left-right order, consistent with the port sequence number on the device. | |
R: Receiving interface T: optical transmitting interface |

Example of the Label
Figure 14-21 shows a sample label on an optical fiber.
- "A01-01-05-01-R" indicates that the local end of the optical fiber is connected to the optical receiving interface 01 in slot 5, chassis 01 in the cabinet in row A, column 01 in the machine room.
- "G01-01-01-01-T" indicates that the opposite end of the optical fiber is connected with optical transmitting interface 01 in slot 01, chassis 01 in the cabinet in row G, column 01 in the machine room.

Example of the Label
Figure 14-22 shows a sample label on an optical fiber.
- "ODF-G01-01-01-R" indicates that the local end of the optical fiber is connected to the optical receiving terminal in row 01, column 01 of the ODF in row G, column 01 in the machine room.
- "A01-01-05-01-R" indicates that the opposite end of the optical fiber is connected to optical receiving interface 1 in slot 05, chassis 01 in the cabinet in row A, column 01 in the machine room.
