Optical transceiver speeds are scaling from 100 Gbps to 400 Gbps, quickly advancing to 800 Gbps, and further toward 1.6 Tbps and beyond. This evolution not only enhances the transmission capacity of optical transceivers but also places greater demands on optical interconnect subassemblies in terms of reliability, coupling efficiency, and compactness. Based on seven core technology platforms, HYC offers flexible customizable integrated subassemblies for 800G/1.6T, Silicon Photonics, optical transceivers.
