DOCSIS, not FTTH, is Technology to Watch
In a sign that consumers and businesses are willing to invest in faster communications despite a slower economy, Dittberner Associates, a market research firm, is reporting this week that shipments of optical fiber-based network architecture systems increased 71 percent in 2008. The company says say that fourth-quarter fiber-to-the-home, or "FTTH" shipments didn't rise as much as first projected, but still topped 3 million for the first time. According to Dittberner, the new technology to watch is not FTTH - the fiber optic cable connection that runs directly from a telephone switch to a subscriber's home - but rather DOCSIS 3.0-based subscribers. The technology - short for "Data over Cable Service Interface Specification" - defines interface standards for cable modems and supporting equipment. The technology lets manufacturers produce cable modems for retail, so consumers no longer have to depend on leased cable modems from their cable providers. Devices that recognize and support the DOCSIS standard include HDTVs and Web enabled set-top boxes for regular televisions.
