Metro Fiber Maps: California

5 Comments

A collection of metro fiber maps for networks within the state of California.  There was a temptation to break this one up into northern and southern portions, given the size of the state.  But as it turns out there are fewer independent metro fiber providers in California than I thought – especially those with public maps.  If the situation warrants, I could split it up later.

Name Maps Lit/dark Comments
Atlantic Metro Los Angeles both On-net list
Charter Business Los Angeles, Bakersfield, San Luis Obispo, Santa Cruz, San Francsico, Modesto, Redding, Crescent City lit
Crown Castle Los Angeles, San Francisco, San Diego, Bakersfield, Sacramento, Fresno both
Digital West San Luis Obispo lit
Edison Carrier Solutions Los Angeles Metro Area both
Level 3 SF Bay Area, Los Angeles/Orange County
San Diego, Sacramento, Fresno, San Luis Obispo
both  Google Maps interface, zoom in
Wave Broadband Bay Area both
Zayo Los Angeles, San Diego, San Francisco, San Jose both
Still seeking maps for the following known providers:
AT&T both
Cogent lit On-net buildings tool
Point to Point Inc dark
Telepacific lit via MPower, former ICG assets in CA
TW Telecom both
XO Communications both

Where possible, all links are to material offered on the websites of the company operating the fiber.  I prefer such links, but will sometimes host the files myself where the operator agrees, and in rare cases may point to third party sources.  Where available, links to on-net building lists are also given.

Additional maps of metro fiber networks that ought to be on this list are very welcome, as are corrections to the above links.  Please just leave a comment below or send an email to info@telecomramblings.com.
