Coherent: Coherent launches 2x400G-FR4 Lite silicon photonics-based optical transceiver

Materials, networking and laser technology firm Coherent Corp of Saxonburg, PA, USA has launched its 2x400G-FR4 Lite optical transceiver, a silicon photonics-based module optimized for AI-driven data centers and high-speed Ethernet networks. Designed for high volume deployments, the transceiver delivers 500m reach while significantly reducing power consumption. It complements the firm's existing 800G-DR8 transceiver (also built with silicon photonics technology) with a wavelength-multiplexed variant that is more fiber-efficient than the DR8...
