Latest Patents

One of Ruai Yu's latest patents is titled "Dynamically optimizing a decision threshold voltage in an optical transponder." This invention involves a transponder equipped with a dynamic remapping circuit that adjusts the decision threshold voltage (Vdtc) and optical power (RXP) to minimize the bit error rate (BER) in communication systems. The dynamic remapping circuit employs a bilinear mapping technique to align the remapped value of Vdtc_opt to a selected normalization value, Vdtc_norm. This innovation ensures that the BER remains below a specified threshold, regardless of variations in RXP or optical signal-to-noise ratio (OSNR).

Another notable patent focuses on "Circuit topologies for high speed, low cost optical transceiver components." This invention presents a new topology that includes an electrical signal interface stage, a data timing and signal reformatting stage, and an optical fiber interface stage. By partitioning functions with the most jitter into the electrical signal interface stage, the design allows for improved performance and production yield. The resulting 40 G transceivers are expected to be smaller, more cost-effective, and more efficient than existing models.
