At the end of each fiber, a flag can be attached with the 

identification of the fiber. The identification is as follows:
Ix.y:  

I=Incoming fiber of the splitter

    

x=splitter number

  y=splitter 

port

Ox.y:  O=Outgoing fiber of the splitter
  x=splitter 

number

  y=splitter 

port

In case of asymmetrical splitters, the identification of the ports can be 
made through the dB value that is written on the back of the flag at the 
end of the fiber.

5.3    Select the appropriate fiber to be spliced, cut the identification 
flag when available and do all necessary steps till the splice protector is 
installed.

Note

: Make sure not to lose fiber identification.

The fiber end can be deformed to create a higher Return Loss on the 
unused fibers.
Make sure to cut the fiber end (50 mm, 2” or behind the ID flag) 
before starting with the splicing steps.

5.4  Proceed with the storage of the splices and the fibers according to 
the installation instruction delivered with the enclosure.

Note

: Make sure the splice protector has cooled down before storing in 

the splice protector modules.
