Description

Description:

The MMF Optical Transceiver Module QSFP-DD 400G is a high-performance, hot-pluggable optical module designed for ultra-high-speed data transmission in modern data center networks and high-performance computing (HPC) environments. Compliant with the QSFP-DD (Quad Small Form-Factor Pluggable Double Density) standard, this module supports 400Gbps aggregate bandwidth over multimode fiber (MMF), delivering reliable and efficient connectivity for short-reach applications.

Highlights:
  • 400Gbps High-Speed: 8 lanes × 50Gbps PAM4 for maximum throughput
  • QSFP-DD Hot-Pluggable: Easy installation and maintenance without downtime
  • Optimized for MMF: Reliable short-reach performance up to 100m (OM4)
  • Energy Efficient: Low power consumption for dense deployments
  • Standards Compliant: Fully compatible with QSFP-DD MSA, CMIS, IEEE 802.3
  • Robust & Reliable: Designed for high-density switches, AI, and cloud data centers
