TS-QDO-854H-01C-V/400G QSFP-DD VR4 VCSEL 850nm 50m MMF MPO Optical Transceiver

       The 400G QSFP-DD VR4 is a hot-pluggable optical transceiver optimized for high-speed 400G Ethernet links in data centers, AI clusters, and HPC environments. Leveraging 4-channel 850nm VCSEL technology and 100G PAM4 modulation, it delivers 425Gb/s full-duplex data transfer over 4 pairs of parallel multimode fiber (OM3/OM4) with FEC enabled, supporting up to 50m on OM4 fiber. Compliant with QSFP-DD MSA, IEEE 802.3db, and CMIS standards, it features an MPO12/APC connector, low power consumption (<8W), and built-in DDM for real-time monitoring. This module offers a cost-effective, high-density solution for short-reach, high-bandwidth data center interconnects, ensuring reliable, low-latency performance for mission-critical applications.
