5.4.2 Engineering Labels for Optical Fibers
These labels are affixed to the optical fibers 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:
l One is for the fiber that connects the optical interfaces on two devices.
l The other is for the fiber that connects the device and the ODF.

Meaning of the Label
Table 5-27 lists information on both sides of the labels affixed to the optical fibers that
connect two devices.

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
