Datacomm (Data Communications) refers to optical and electrical technologies used to transmit digital data between systems such as servers, switches, and storage equipment. In photonics, datacomm commonly includes short- and medium-reach fiber links using transceivers, lasers, and photodiodes operating at defined wavelengths and data rates. Performance is driven by bandwidth, sensitivity, and signal integrity. GPD Optoelectronics manufactures photodiodes used in datacomm optical receivers.
Everyone’s talking GPUs, but the AI buildout has a quieter bottleneck: getting data into and out of chips fast enough. As data centers push toward 800G and 1.6T, silicon can’t detect the light. Germanium and InGaAs photodiodes are the unsung heroes making it work.
