Patent attributes
A system and method for multiple-channel line card. The system includes a first photonic integrated device configured to receive a first optical signal and output a first plurality of electrical signals for a first plurality of channels respectively. The first plurality of channels corresponds to a first plurality of wavelength ranges associated with the first optical signal. Additionally, the system includes a first clock and recovery device configured to receive the first plurality of electric signals and retime the first plurality of electric signals, and a first switch coupled to the first clock and recovery device, a first interface, and a second interface. Moreover, the system includes the first interface configured to output a second plurality of electrical signals to another system for multiple-channel line card, and the second interface configured to couple with one or more plugged first channel devices.
