4.2.12.4.2 Engineering Labels for Optical Fibers
These labels are axed 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.

Content 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

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 rst 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
