Description

Long-reach 400G active optical cable designed for QSFP-DD switch and adapter ports across Ethernet or InfiniBand fabrics. The integrated 850nm optics provide consistent performance up to 50m while minimizing weight and heat compared to copper. Ideal for row-to-row or aggregation uplinks in HPC and AI clusters. Blue jacket for quick visual identification.

Features

- 400G performance over 50 meters for flexible rack-to-rack runs
- QSFP-DD integrated optics—no separate modules or patch cords
- Lightweight and easy to manage in overhead trays

FAQs

Q: When should I choose a 50m AOC instead of transceivers plus patch fiber?
A: Choose a 50m AOC for simplified installation, guaranteed end-to-end performance, and predictable cost when reach needs exceed typical DAC limits but stay within 50m.

Q: Is it suitable for AI/ML cluster interconnects?
A: Yes. It is commonly used for spine–leaf and GPU node uplinks in AI/HPC fabrics using QSFP-DD 400G ports.

Q: Does it support link monitoring?
A: Yes. The integrated QSFP-DD ends provide DOM/diagnostics and inventory information where supported by the host.

Q: What bend radius should I follow?
A: Follow standard fiber handling practice and the equipment vendor’s guidelines to avoid tight bends or pinches that could degrade performance.
