Abstract
Following the field's general trend to enhance system transport capacity by increasing the formats' carrier frequencies and payloads, a novel approach is reported for 2.5 Gbit/s signalling at a carrier frequency of 625 GHz. Duobinary baseband modulation on the transmitter side generates a signal with a sufficiently narrow spectral bandwidth to pass an upconverting frequency multiplier chain. Power, bit error rate, and signal-to-noise ratio measurements on the receiver side describe the signal performance.Keywords
