A quad small form-factor pluggable (QSFP) parallel optical transceiver with data rate up to 10 Gbit/s per channel for very short reach(VSR) interconnection based on system in package(SiP) technology is implemented and tested.An 850 nm vertical cavity surface emitting laser(VCSEL) array with a laser driver is used as the light source of the transmitter,and a photodiode(PD) array with a trans-impedance amplifier plus limiting amplifier(TIA/LA) is used as the detector of the receiver.An innovative ...
