Abstract
A high-speed optical data link includes a system circuit board, a first ASIC coupled to convey electrical information to and from up level data management circuits, and a second ASIC electrically coupled to the first ASIC. A fiber optic module mounted on the system circuit board including a receiver, a transmitter and the second ASIC. The receiver includes a photo-diode positioned to receive optical signals, a trans-impedance amplifier electrically coupled to the photo diode, and a post-amplifier electrically coupled to the trans-impedance amplifier and to the second ASIC. The transmitter includes a laser positioned to convey optical signals to a remote optical receiver and a laser driver electrically coupled to the laser and to the second ASIC. Both the first and the second ASICs include clocking and equalization/retiming functions for recovering distorted data transmitted therebetween through electrical traces on the system circuit board so as to send electrical data at rates equal to or higher than 10-Gbps.
