WaveSplitter X DWDM components can be used on any fiber-optic system. They address the needs and resources of the metro, campus, and other MAN providers. The system begins with a 100-GHz, 1ٶ Base-wave device. System output meets any wavelength defined by the ITU grid and within the EFA bandwidth. The Base-wave device can stand alone, providing four channels with 0.8-nm separation, or it can be combined with sub-splitter components in a tree or cascade configuration. By the addition of from one to 20 sub-splitters, system output can expand to any number of channels on the ITU grid, from four to 64.
