S-CDMA

(Synchronous CDMA) A cable modem technology from Terayon Communication Systems, Santa Clara, CA (www.terayon.com) that provides 10 Mbps transmission in both directions. Certified to the DOCSIS 2.0 specification in 2003, S-CDMA works well in noisy environments. It is suited for cable plants that are entirely coax based or that do not have optimum systems. In 2007, Terayon was acquired by Motorola.
