Coherent Corp. announced the launch of its 2x400G-FR4 Lite optical transceiver, a silicon photonics-based module optimized for AI-driven data centers and high-speed Ethernet networks. This transceiver is designed for high-volume deployments and delivers a 500-meter reach while significantly reducing power consumption.
The 2x400G-FR4 Lite complements the company’s existing 800G-DR8 transceiver with a wavelength-multiplexed variant that is more fiber-efficient. Dr. Lee Xu, Executive Vice President, Datacom Transceivers, emphasized that silicon photonics was the optimal choice for this application, reinforcing Coherent's commitment to selecting the best technology for each use case.
The module integrates a silicon photonics integrated circuit (PIC) to reduce component count and streamline production, including CW lasers, photodetectors, and passive optical components, and eliminates the need for thermoelectric coolers. Samples are available now, with general availability planned for April 1, 2025.
