The Optical Transceiver 800G OSFP-Flat 2×VR4 is designed to deliver high-speed, short-reach optical connectivity for AI-driven and hyperscale data center environments. Supporting eight 106.25Gbps PAM4 channels, this transceiver enables efficient 800G Ethernet and InfiniBand connectivity over multimode fiber using parallel optical interfaces.
Built with VCSEL transmitters and PIN receivers, the module operates at an 850nm wavelength and features dual MPO-12 connectors to support two independent VR4 optical links. It delivers reliable optical performance over distances of up to 30 meters on OM3 and up to 50 meters on OM4/OM5 fiber. The OSFP-Flat form factor enables integration in systems with tighter mechanical or thermal constraints, while commercial temperature operation and a maximum power consumption of 15W ensure stable performance in dense deployments. This transceiver is well suited for production-ready AI clusters and modern data center architectures requiring scalable, short-reach 800G optical solutions.
