SKU: ROADM
The Reconfigurable Optical Add/Drop Multiplexer (ROADM) switch is built on a proprietary micro-optics and micro-actuator platform with athermal grating packaging for stable wavelength performance. When a multi-wavelength optical signal enters the Input Port (IN), the ROADM dynamically routes a selected wavelength channel to the Drop Port while passing the remaining channels to the Express Port (EXP). A channel can also be inserted through the Add Port to enable simultaneous add-and-drop operation. The standard configuration supports up to 48 ITU channels with 100-GHz or 200-GHz spacing, with the option to add or drop up to any four channels at once. Extended versions covering the full C-band, full L-band, or customized band-partitioned drop configurations are available upon request.
Due to inherent computer delays under Windows, response speed can be improved by using a Linux-based controller or executing stored switching sequences directly on the board. In this mode, the host computer simply issues start, pause, and repeat commands.
