Description

Short-reach Active Optical Cable breakout that splits one 400G QSFP56-DD port into four 100G QSFP28 links. Ideal for very short but flexible optical runs in dense racks when copper isn’t suitable. Implements 400GBASE-SR8 and 100GBASE-SR4 for seamless interoperability.

Features

- Ultra-short 1m optical breakout for dense deployments
- 400G-to-4x100G with 1x4 fan-out using QSFP56-DD and QSFP28
- Standards-based 400GBASE-SR8/100GBASE-SR4 compatibility
- Integrated optics with digital diagnostics
- Lightweight and flexible cable assembly
- Low EMI and easy cable management

FAQs

Q: Is this suitable for top-of-rack connections?
A: Yes. The 1m AOC is ideal for very short, flexible runs within the rack when optical cabling is preferred.

Q: Does the host need to be configured for breakout?
A: Yes. Enable 1x4 breakout on the 400G port so it presents as four 100G interfaces.

Q: Is external fiber required?
A: No. The AOC includes integrated multimode fiber and optical engines.

Q: Is FEC required?
A: Yes. RS-FEC is generally required by the 400GBASE-SR8/100GBASE-SR4 standards.

Q: Can I intermix with DAC breakouts?
A: Yes, provided your topology and port settings support the mix; ensure all links meet their reach and loss budgets.
