DESC: CWDM GBICs are transceivers that link Gigabit Ethernet ports with fiber optic networks. WDM technology consolidates multiple optical channels on a common optical fiber, using specific wavelengths to expand available bandwidth.??CWDM GBICs are a component in the optical routing system designed to support high-speed data communication for Metropolitan Area Networks (MANs). The system uses a grid of eight CWDM optical wavelengths in both ring and point-to-point configurations. All components are color-coded by wavelength.??The wavelength color code of this converter is violet.
