400G QSFP-DD SR8 100m
Posted on 2025-06-26

The 400G QSFP-DD SR8 100m transceiver is a high-speed optical module in QSFP-DD form factor, delivering 400Gbps bandwidth through 8-channel 850nm VCSEL arrays and PAM4 modulation. Operating on OM4 multimode fiber (supporting 100-meter reach), it features an MPO-16/APC connector to minimize reflections. With sub-10W power consumption and compliance to IEEE 802.3cm/QSFP-DD MSA standards, it enables seamless integration with 200G/100G infrastructure. Ideal for high-density data center interconnects, this module efficiently supports leaf-spine switching, HPC clusters, and cloud networks requiring cost-effective, low-latency 100m connectivity.
