Santa Fe Fiber maintains a separate fiber path, independent of other carriers, from the State IT Center on Alta Vista to the Railyard and on to Santa Fe Main (the CenturyLink Central Office) on East Alameda. It can provide dark fiber between each of its three points of presence. In particular, carrriers that co-locate at the State IT Center and Santa Fe Main can benefit from the availibility of dark fiber. Please give us a call at 795-7000.
