These utilize light-emitting diodes (LEDs) and laser diodes to transmit data over fiber-optic cables at massive speeds. Recent research has even demonstrated Mach-Zehnder modulators reaching rates of 480 Gbit/s .
The field of communications engineering is built upon specialized circuits designed to manipulate signals with extreme precision. From the earliest radio transmissions to modern fiber-optic 5G networks, these circuits perform the critical tasks of amplifying, filtering, and converting data into formats suitable for transmission across various media. 1.
