visaris writes " reports researchers at IBM have set a new record for data transmission over a multi-mode optical fiber. The record data rate of 64Gb/s was achieved over a cable 57 meters long, using non-return-to-zero (NRZ) modulation with a type of laser called a vertical-cavity surface-emitting laser (VCSEL). Researcher Dan Kuchta notes, "Others have thought that this modulation wouldn't allow for transfer rates much faster than 32 Gb/s." Indeed, many researchers thought that achieving higher transmission rates would require turning to more complex types of modulation, such as pulse-amplitude modulation-4 (PAM-4). The achievement demonstrates that standard, existing technology for sending data over short distances should be able to meet the growing needs of servers, data centers and supercomputers through the end of this decade, according to the researchers. "What we're showing is that [...] this technology has at least one or two more generations of product life in it," says Kuchta."
