Coherent Introduces Advanced 2x400G-FR4 Lite Transceivers
Coherent Introduces Cutting-Edge 2x400G-FR4 Lite Optical Transceiver
Coherent Corp. (NYSE: COHR), a renowned innovator in photonics, has rolled out its latest optical transceiver, the 2x400G-FR4 Lite. This new module is tailor-made for AI-driven data centers and high-speed Ethernet networks. One of its standout features is its impressive reach of 500 meters, all while minimizing power consumption, making it ideal for extensive deployment scenarios. The 2x400G-FR4 Lite complements Coherent's existing lineup, including the advanced 800G-DR8 transceiver, which also leverages silicon photonics technology but is designed for broader wavelength multiplexing and fiber efficiency.
The Growing Demand for Efficient Optical Interconnects
The surge in artificial intelligence (AI) and machine learning (ML) workloads is significantly shaping the landscape for optical interconnects. These workloads necessitate high-density and energy-efficient connections that seamlessly fit into the Ethernet-based networks prevalent today. By integrating silicon photonics, the 2x400G-FR4 Lite provides a streamlined design that enhances efficiency and presents a modern alternative to conventional electro-absorption modulated laser (EML) solutions, especially for applications that require shorter reach.
Technological Leadership and Innovation
Dr. Lee Xu, Executive Vice President of Datacom Transceivers at Coherent, emphasized the advantages of the silicon photonics approach, stating, "The 2x400G-FR4 Lite embodies our dedication to selecting the technology that best suits each application. Our diverse technology portfolio incorporates vertical cavity surface-emitting lasers (VCSEL), EML, directly modulated lasers (DML), along with silicon photonics. This enables us to customize our solutions for optimal performance, efficiency, and cost-effectiveness." This commitment to innovation is evident in every facet of the new transceiver, enabling it to excel in demanding environments.
Technical Features of the New Transceiver
Integrating a silicon photonics integrated circuit (PIC) into the 2x400G-FR4 Lite has led to a reduced component count, streamlining the manufacturing process. This optical transceiver features continuous wave (CW) lasers, photodetectors, and passive optical components, eliminating the necessity for thermoelectric coolers, thus enhancing its overall efficiency and reliability.
Availability and Industry Engagement
Currently, samples of the 2x400G-FR4 Lite are available for evaluation, with a full product release scheduled for April 1, 2025. Industry professionals are invited to visit booth #1519 at OFC 2025 in San Francisco from April 1 to 3 for an in-depth exploration of this innovative transceiver and other silicon photonics solutions from Coherent.
