Marketing Information ADD-GMC-2SFP is a Media Converter with two Open SFP Port slots, allowing for the conversion among a variety of fiber types. First, it acts as a wavelength switch device, and can provide transmission between two wavelengths, 1310nm to 1550nm, 1310 to 850nm or 850nm to 1550nm. Second, ADD-GMC-2SFP also acts as a mode switch device, and can provide transmission between multi-mode (850nm, 1310nm) and single mode (1310nm, 1550nm). Finally, ADD-GMC-2SFP acts as a fiber switch device and provide data transmission between single-fiber and dual-fiber.
