Semtech and Multiphydemonstrate a single-lambda 100G solution at ECOC for DR4 modulation in a QSFP28. This included a single channel PAM-4 DSP from Multiphy, and modulator driver and TIA from Semtech.

“Single wavelength 100G is the ultimate solution for 100G in the data center, offering four times of fundamental cost improvement over existing 4x25Gbps solutions. This will be the preferred technology for high-volume applications in Cloud and colocation data centers,” said Andrew Schmitt, Founder at Cignal AI. “This new 100G chipset provides performance of greater than 2 km, effectively meeting all single mode needs for next-generation hyper-scale data centers.”
