The growing demand for data centers, backbone, access, and wireless networks requires innovative concepts for the transmission and distribution of digital or analog signal waveforms. We present a new, extremely simple transceiver concept that differs fundamentally from conventional approaches. It does not require high-speed electronics and enables the transmission of various time-multiplexed analog waveforms or digital data signals at the maximum possible symbol rate in the same rectangular optical spectral band B. The total symbol rate of N signal channels corresponds to B or twice the electro-optical bandwidth of the modulator used. By modifying the system, it can be increased to three times the modulator bandwidth. Since no optical filter, high-speed signal processing, or unconventional photonic components are required, the system can be easily integrated into any platform and offers an economical and energy-efficient solution for future communication networks and microwave photonic connections.
