Lumentum and Marvell exhibit integrated 450G optical interface
Photonics firm Lumentum and Marvell Technology, a maker of data infrastructure chips, has announced an industry-first demo integrating Marvell 400G/per lane PAM4 technology operating at 225 Gbaud with Lumentum’s InP monolithically-integrated DFB-MZI optical transmitter.
The combination is being shown at the 2025 Optical fibre Communications Conference and Exhibition (OFC) in San Francisco, California, April 1-3 2025.
Lumentum's DFB-MZI transmitter integrates a 450G PAM4 distributed feedback (DFB) laser with a Mach-Zehnder (MZI) modulator, using the company’s InP technology.
According to the company, the integrated DFB-MZI solution offers clear performance advantages over silicon photonics, particularly in applications where signal integrity and efficiency are critical.
