Q1: What is an Active Optical Cable (AOC)?
A: An Active Optical Cable (AOC) is a fiber-based cable assembly with integrated transceivers on both ends, designed to provide high-speed data transmission over longer distances compared to copper cables.
Q2: What data rates are supported by AOC cables?
A: AOC cables support multiple data rates, including 10G, 25G, 40G, 100G, 200G, and 400G, depending on the connector type and cable design.
Q3: What are the main advantages of using AOC cables?
A: AOC cables offer longer reach, lighter weight, better EMI resistance, and lower power consumption compared to traditional copper cables, making them ideal for data center environments.
Q4: What is the typical transmission distance of AOC cables?
A: AOC cables typically support distances from 5m up to 100m or more, depending on the data rate and fiber type.
Q5: How do AOC cables differ from DAC cables?
A: AOC cables use optical fiber for signal transmission, while DAC cables use copper conductors. AOCs are better suited for longer distances, while DACs are typically used for very short-range connections.
Q6: Are AOC cables compatible with Cisco, Juniper, and HPE devices?
A: Yes. These AOC cables are fully compatible with Cisco, Juniper, HPE, and other major networking brands, and are coded to meet MSA and device compatibility standards.
Q7: What connector types are available for AOC cables?
A: AOC cables are available with SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, and QSFP112 connectors, depending on the supported data rate.
Q8: What is an AOC breakout cable?
A: An AOC breakout cable allows a single high-speed port to be split into multiple lower-speed ports, enabling flexible port utilization in high-density network deployments.
Q9: What breakout configurations are available for AOC cables?
A: AOC breakout cables typically support 1×2 and 1×4 configurations, depending on the data rate and switch port capabilities.
Q10: Which data rates support AOC breakout cables?
A: AOC breakout cables are commonly available for 40G, 100G, 200G, and 400G applications.
Q11: What is a 40G AOC breakout cable commonly used for?
A: A 40G AOC breakout cable is commonly used to split one 40G QSFP+ port into four 10G SFP+ ports for server or access-layer connectivity.
Q12: How are 100G AOC breakout cables typically configured?
A: 100G AOC breakout cables are typically configured as 1×100G to 4×25G or 2×50G, enabling flexible network scaling.
Q13: What breakout options are available for 200G and 400G AOC cables?
A: 200G AOC cables can be configured as 1×200G to 2×100G or 4×50G, while 400G AOC cables support 1×400G to 2×200G or 4×100G configurations.
Q14: Do AOC breakout cables require special switch configuration?
A: Yes. The connected switch must support breakout functionality, and the port configuration must be properly set in the switch operating system.
Q15: Can AOC cables be used for top-of-rack (ToR) connections?
A: Yes. AOC cables are widely used for top-of-rack, leaf-spine, and server-to-switch connections where longer reach and cable flexibility are required.
Q16: Are AOC cables hot-swappable?
A: Yes. AOC cables support hot-swappable installation, allowing them to be connected or replaced without powering down network equipment.
Q17: Do AOC cables support Digital Diagnostic Monitoring (DDM)?
A: Yes. Most AOC cables support DDM, enabling monitoring of temperature, voltage, and optical signal parameters.
Q18: What environments are AOC cables best suited for?
A: AOC cables are ideal for data centers, cloud computing environments, AI and HPC clusters, and enterprise networks requiring high-speed, medium-distance connectivity.
Q19: Are these AOC cables tested before shipment?
A: Yes. Each AOC cable is individually tested for signal integrity, compatibility, and performance before shipment.
Q20: Can AOC cable length and compatibility be customized?
A: Yes. AOC cables can be customized in length and coded for specific switch or server models upon request.
Q21: Are AOC cables immune to electromagnetic interference (EMI)?
A: Yes. Because AOC cables use optical fiber, they are highly resistant to electromagnetic interference, making them suitable for dense or noisy environments.
Q22: What is the difference between AOC and optical transceivers with fiber patch cables?
A: AOC cables integrate transceivers and fiber into a single assembly, offering simplified installation, while optical transceivers with patch cables provide more flexibility for longer or modular links.
Q23: What warranty is provided for AOC cables?
A: All AOC cables are backed by a standard warranty and professional technical support, ensuring long-term reliability and customer confidence.
