Hi Arpita Gupta,
in order to represent the optical code for each user. you can use even just one optical source. since one source is applicable to support up to 20 wavelengths. in that, you can use WDM Demus to slice the broadband spectrum. As mentioned above, FBG can be used to represent each code length.
Regards
