Description

High-performance 400G active optical cable with integrated QSFP-DD transceivers for short-reach switch/server interconnects. Delivers low-latency, low-power 8x50G PAM4 lanes over multimode optics for simple, reliable 400GbE deployments. Ideal for top-of-rack to aggregation links where fixed lengths and cable management matter.

Features

- Plug-and-play QSFP-DD to QSFP-DD 400G connectivity
- Integrated optics reduce transceiver procurement and compatibility risks
- Flexible, lightweight cabling for improved airflow and cable management
- Low latency and low power versus discrete optics + patch leads
- Factory-terminated ends eliminate contamination and insertion-loss variability
- MSA-compliant for broad platform interoperability
- Ideal for TOR-to-spine and server-to-switch links up to 10m

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

FAQs

Q: Will this AOC work between two 400G QSFP-DD switch ports?
A: Yes, it is designed for 400GbE QSFP-DD ports on switches, NICs, and adapters.

Q: What is the difference between AOC and DAC?
A: AOCs use optical fiber and integrated optics for longer reaches and better cable flexibility; DACs use copper and are typically limited to shorter distances.

Q: Do I need separate transceivers with this cable?
A: No. The QSFP-DD optical modules are integrated at both ends of the AOC.

Q: Is this compatible with multimode environments?
A: Yes. It uses 850nm optics suitable for short-reach multimode applications.

Q: Can it operate bidirectionally?
A: Yes, it provides full-duplex 400GbE operation over the integrated optical lanes.
