Abstract
A plug-in, optical add/drop (OAD) device includes a filter for adding and dropping a light beam of wavelength (λ) from a combined light beam having individual beams of different wavelengths (λ). Several devices can be selectively integrated to create an optical communications system that will handle 'n' different optical communications circuits. In operation, the devices are individually connected (plugged-in) to a GBIC, and they are serially connected (plugged-in) to each other. Consequently, immediately upstream from a device, the combined light beam includes wavelengths (λthrough λ). On the other hand, the combined light beam immediately downstream includes (λthrough λand λthrough λ).
