Molex Debuts 100G PAM-4 Based 25G/50G/100G/400G Product Solutions

Molex today announced a portfolio of 100G and 400G products based on its 100G PAM-4 optical platform, including multi-Rate 25G/50G/100G PAM-4 DWDM QSFP28, 100G FR QSFP28, 400G DR4 and 400G FR4 QSFP-DD and OSFP.

"Molex (News - Alert) is a leader in the development of the foundational building blocks for 100G PAM-4 optoelectronics, and in collaborations for digital signal processing (DSP) integrated circuits. By leveraging these combined capabilities, we support high bandwidth requirements for a wide range of applications across intra-data center, data center interconnect (DCI) and 5G wireless. In addition, 100G PAM-4 technology also lays the foundation for cost-effective and high-density 400G solutions," said Rang-Chen (Ryan) Yu, vice president of business development, GM of optoelectronic solutions at Oplink, a Molex Company and co-chair of 100G Lambda MSA.

Molex is actively promoting an industry-wide adoption of 100G PAM-4 technologies through standards such as the IEEE (News - Alert), and multi-source agreement (MSA) forums such as the 100G Lambda MSA (
