Cox Communications 122-fiber-strand optic cable is being used to deliver high speed Internet and San Diego Padres to the residents of Tijuana, Mexico according to San Diego. This is the only US fiber optic cable to cross an international boundry, reports San Diego Union Tribune. The cable stretches across the Tijuana River Valley on utility poles before it drops in and connects to the lines owned by Cablems, a Tijuana cable TV company.
