Light Reading's projection on adoption rates by carriers of technologies by 2003 lightreading.com First, grooming switches, which pack circuits into wavelengths before switching them. The CoreDirector from Ciena Corp. (Nasdaq: CIEN - message board) is a notable example of this. Second, wavelength switches, which switch whole wavelengths. These come in OEO form (think Tellium Inc. [Nasdaq: TELM]) and OOO form (think Calient Networks Inc. and Corvis Corp. [Nasdaq: CORV]). Third, fiber switches, which are really automated patch panels that switch all of the wavelengths from one fiber to the next, as a group. The early version of LambdaRouter from Lucent Technologies Inc. (NYSE: LU - message board) is an example. In most instances, manufacturers start by making a fiber switch and then add some multiplexing functions to offer a wavelength switch. All three types of switch appear to be heading for widespread deployment. Interestingly, grooming switches don’t seem any more popular than wavelength or fiber switches – in spite of all of the market noise surrounding Ciena’s Core Director.
