400G QSFP-DD SR8

Overview

The 400G QSFP-DD SR8 transceiver uses 8-lane parallel 850nm VCSEL with PAM4 modulation and an MPO-16 interface to deliver 400G short-reach over multimode fiber (70m OM3 / 100m OM4), with flexible breakout — a high-density interconnect for data center Spine-Leaf and server access.

Features

Ultra-high bandwidth: 400Gbps with 8-lane parallel transmission for massive throughput.

High density: QSFP-DD packaging suits large-scale data center deployment.

Flexible breakout: Splits into 2x200G or 8x50G links for higher port utilization and lower cost.

Short-reach cost-effective: Pairs with OM3/OM4 multimode fiber within 100m.

Hot-swappable: Online replacement and upgrades without service disruption.

Applications

AI/HPC intra-rack low-latency high-bandwidth data paths, data center Spine-Leaf switching, TOR-to-server access, mixed-rate 200G/50G networking via breakout.
