Intel has unveiled a new and powerful transceiver for 2019 at the the Optical Fiber Communications (OFC) conference in San Diego. This module, the Stratix 10 TX, enables data-transmission rates of as much as 58 gigabits per second (Gb/s). In practice, this translates to Ethernet bandwidth of up to 400Gb.
