400G QSFP-DD AOC (Active Optical Cable) is a high-speed active optical cable used to connect data centers, computer networks, and communication equipment. It utilizes the QSFP-DD (Quad Small Form-factor Pluggable Double Density) interface and supports a transmission rate of 400Gbps. The AOC cable consists of an active optical module and optical fibers, with the optical module containing optoelectronic converters that convert electrical signals to optical signals for high-speed transmission through the optical fibers. This cable offers high bandwidth, low latency, and stable data transmission, making it suitable for applications that demand high-speed data transfer performance. It is capable of high-speed data transmission over short distances while maintaining low power consumption and high reliability.

A1: An Active Optical Cable (AOC) integrates fiber optic technology with built-in transceivers to deliver high-speed data transmission (10G-400G) without separate optical modules. Unlike traditional fiber patch cables, AOCs offer plug-and-play simplicity for data center interconnects. Q2: Why Choose AOC Over DAC for Data Center Networking? A2: AOC cables outperform Direct Attach Copper (DAC) in four key ways: longer reach (up to 100m vs 7m), EMI immunity, lower power consumption (30% less than active DAC), and lighter weight - critical for high-density 100G/400G deployments. Q3: What Are the Maximum Speeds Supported by Modern AOC Cables? A3: Today's AOC solutions support: 10G/25G (SFP+/SFP28) 40G/56G (QSFP+) 100G (QSFP28) 200G/400G (QSFP-DD/OSFP) Perfect for hyperscale data centers upgrading to 400G Ethernet. Q4: What's the Maximum Reliable Distance for QSFP28 AOC Cables? A4: Standard 100G QSFP28 AOCs reliably transmit up to 100m (OM4 fiber), with premium models reaching 300m - ideal for campus data center interconnects and HPC clusters. Q5: How Do AOC Cables Reduce Data Center OPEX? A5: Three OPEX advantages: 40% lower power than copper alternatives Zero maintenance (no signal degradation) 60% lighter weight reduces cooling costs Q6: Can I Use QSFP+ AOC for Breakout to SFP+ Connections? A6: Absolutely! Our QSFP+ to 4x SFP+ breakout AOCs enable: Cost-effective 40G migration Flexible spine-leaf architectures Simplified cable management Q7: Do AOC cables require special maintenance? A7: No, AOC cables are durable, require no signal conditioning, and are more resistant to environmental factors than copper cables, reducing maintenance needs in data center environments. Q8: Can AOC cables be used for breakout configurations? A8: Yes, our QSFP+ to 4x SFP+ AOC breakout cables enable flexible 40G to 10G migration paths for cost-effective network upgrades. Q9: How do AOC cables compare to traditional optical transceivers? A9: AOC offer plug-and-play simplicity by eliminating separate transceivers, reducing points of failure while maintaining the benefits of optical transmission. Q10: Are AOC cables compatible with major switch brands? A10: Yes, our AOC cables are MSA-compliant and work with major networking equipment brands for seamless 40G/100G connectivity.
