Mesh Optical Technologies is a startup founded by former SpaceX engineers focused on mass-producing optical transceivers. These devices are crucial for converting optical signals to electrical signals for computers, particularly in data centers that train and operate large deep learning models. The company aims to address limitations in the current optical transceiver market, which is largely dominated by Chinese firms, by building a supply chain outside of China and leveraging automated manufacturing techniques for more efficient and lower-cost components. Their technology can also reduce GPU cluster power usage.
