Data Center Optical Module Technology and Its Evolution
Network bandwith multiplies and power consumption of data centers increases exponentially.SiPh and co-package optics(CPO)may be long-term solutions around the technical requirements of low-power consumption and high-bandwidth.SiP chips can be optical in-terconnection.Using SiPh and CPO stacking techniques which can realize co-package of optical engines and switch chips,power consump-tion can be greatly reduced when transmission rate inreases.Besides,liquid cooling technology,linear-drive pluggable optics(LPO),coher-ent technology,and thin film lithium niobate will be main development trends of optical modules.LPO should be quick landing with vigorous promotion of high-linearity trans-impedance amplifier(TIA)/driver manufacturers.Coherent lite solution becomes competitive when solving under 2 km transmission in data centers.
