Copper cabling has been the workhorse for moving data inside of AI and HPC data centers, but fiber is nipping at its heels. Optics brings three possible bandwidth multipliers — wavelength-division ...

A direct modulation bandwidth of 66 GHz has been achieved from two daisy-chained VCSELs, and the principle could be scaled up to reach over 100 GHz. An international research team has shown that a ...

As optical bandwidth requirements increase, system designers are turning to “coherent” modulation schemes that can place more data on the same laser light, and lower power over long connections. A ...

Ever increasing data-transmission speeds coupled with the need to contend with higher-order modulation schemes are presenting optical-communications test-and-measurement challenges. Products ranging ...
