2.10 Fiber Optic labels:

A. The jacket of the OSP cable shall be labeled at each end and inside each pull box with the MINES
assigned cable number with black on orange for multi mode and black on yellow for single mode.

B. The assigned cable numbers for multi mode are 1000-1xxx to be assigned by MINES CCIT (add M5 to
the end of the cable number for 50 micron fiber). The assigned cable number for single mode is 2000-
2xxx to be assigned by MINES CCIT. The assigned cable number for any hybrid cable is 3000-3xxx to
be assigned by MINES CCIT.

C. These cable numbers must be preceded with MINES building codes. Example: An OSP fiber cable from
Berthoud Hall to the GRL building would be BE-RL-1025.

D. The inside plant fiber optic cables shall be labeled at each end with the assigned MINES cable
numbers, black on orange for multi mode and black on yellow for single mode.

E. The assigned cable number for multi mode is 4000-4xxx (add M5 to the end of the cable number for
50 micron fiber). The assigned cable number for single mode is 5000-5xxx.

G. On the patch panels themselves the labels should be a set of 2 lines for each fiber. The labels are
of the format:


[Far end]

[Near end]



a. Where each code is:


[Building] [TR room code] – [Fiber LIU #] – [fiber port] [S or M or M5]

b.
Example: For a single mode fiber between Berthoud Hall and the GRL building, if the
fiber is in LIU 3 in Berthoud Hall and in LIU 1 at the GRL building, the code at the GRL
building is:
BE2-3-10S
RL1-1-10S

This would be a single mode fiber strand that is terminated in the GRL building data
room 1, in LIU 1 on port 10. The other end is in Berthoud Hall data room 2 (where the
GRL cable terminates), on LIU 3, port 10.

c.
For the intra-building fiber, an example would be:
RL2-1-24M
RL1-1-12M
This is a multi mode fiber terminated in data room 2, in LIU 1, port 24. The other end of
the fiber is in data room 1, LIU 1, port 12.
