In Part 1, we saw that, at transmission rates over about 30 Gbaud and especially for notoriously noise-limited PAM4 (4-level pulse amplitude modulation) signals, S-parameter mask requirements (Figure ...
Jenoptik is one of the few companies in the world to address the market for pulse modulation of high and low power lasers. The Digital Imaging business unit presents at Photonics West their highly ...
Cyanobacteria, an ancient lineage of bacteria that perform photosynthesis, have been found to regulate their genes using the same physics principle used in AM radio transmission. New research ...
PAM-4, which could be a catalyst for reaching 400-Gb/s Ethernet, will also likely find homes in high-speed serial interfaces such as FibreChannel. Pulse amplitude modulation (PAM) is a way to pack ...
