Overlay maps of fiber routes through Louisiana

Hi, Does anyone have any links, maps, etc, that shows an overview of which fiber providers traverse Louisiana, touching Baton Rouge, which do not have eastbound paths dependant on New Orleans facilities? I am not looking for exact routes, yet. I know the general one that was generated for the state in 2002. Looking for OC-48 links. Please contact me off list. Providers contacting me is ok. Thank you G
