Patent attributes
An optical bridge for switching between a plurality of electrical chips, the optical bridge comprising: a passive optical router; and a plurality of Bridge Interface Chips optically connected to the passive optical router; each Bridge Interface Chip being connectable to one of the plurality of electrical chips to form a connection between that electrical chip and the passive optical router at which electrical signals from the electrical chip are converted into wavelength tunable modulated optical signals for transmission to the passive optical router and at which an optical signals from the passive optical router are converted into electrical signals to be received by the electrical chip; wherein each Bridge Interface Chip includes a wavelength tunable laser input and a modulator for modulating the wavelength tunable laser input to provide the wavelength tunable modulated optical signals.
