Coherent to demonstrate 1.6T-DR8, 800G-DR4 transceivers at ECOC 2024

Coherent Corp. announced the demonstration of two advanced transceiver modules at the European Conference on Optical Communication 2024, set to take place in Frankfurt, Germany, September 23-26. These modules, both operating at 200 Gbps per lane, demonstrate the company’s commitment to continued leadership and innovation across multiple optical technologies. The next-generation 1.6T-DR8 transceiver module in the OSFP standard enables data center interconnects, with eight electrical and eight optical lanes each running at 200 Gbps for a total capacity of 1.6 terabits per second. The module incorporates an advanced digital signal processor provided by NVIDIA and is purpose-built for artificial intelligence and networking applications. Capable of transmitting over distances of up to 500 meters via eight pairs of single-mode fiber, this transceiver showcases silicon photonics technology from Coherent, which balances top-tier performance with scalability. The second featured demonstration will be the 800G-DR4 transceiver, also in the OSFP format. Equipped with eight electrical lanes running at 100 Gbps and four optical lanes at 200 Gbps, this module is designed for a 500-meter range over four pairs of single-mode fiber. It utilizes the proprietary 200G differential electro-absorption modulated laser technology from Coherent, which enhances signal integrity compared with conventional single-ended EML solutions. This advancement ensures superior performance, especially in next-generation high-speed data center environments, where maintaining signal fidelity is crucial.
