AOC Cables

An AOC (Active Optical Cable) is a high-speed, It uses electronic modules at both ends to convert electrical signals into optical signals and then convert them back.Fiber-optic cabling solution,Engineered for data centers, cloud and HPC environments, our AOC cables support speeds from 10Gbps up to 800Gbps over multimode fiber—eliminating bulky transceiver modules and fully IEEE 802.3 compliant and compatible with all leading switch and server vendors. Lightweight and flexible, they simplify installation and reduce total cost of ownership—making them the ideal choice for modern, high-density optical interconnects.

FAQs About Active Optical Cables

What are the primary uses of Active Optical Cables?

AOC cables are ideal for data centers, high-performance computing (HPC), and telecom applications, including rack-to-rack connections, storage systems, and switch-to-server interconnects requiring high bandwidth and low latency.

What data rates do Active Optical Cables support?

AOC cables support a variety of speeds, including 10Gbps (SFP+), 25Gbps (SFP28), 40Gbps (QSFP+), 100Gbps (QSFP28), 200Gbps (QSFP56), 400Gbps  and up to 800Gbps.

What’s the difference between AOC and DAC Cables?
  • AOC Cables: Use fiber optics, support longer distances (up to 100m), are lighter, and are immune to electromagnetic interference (EMI). They’re ideal for high-density, longer-range connections.
  • DAC Cables: Use copper, are limited to shorter distances (up to 7m), are more cost-effective, and consume less power but are heavier and susceptible to EMI.
Are AOC Cables compatible with my equipment?

AOC cables are designed to comply with industry standards (e.g. SFP+, QSFP28). Please be sure to confirm the compatibility of AOC with your equipment or consult your supplier.

What are breakout AOC Cables?

Breakout AOC cables split a high-speed port into multiple lower-speed ports (e.g., 100G QSFP28 to 4x 25G SFP28), offering a cost-effective way to connect devices with different port speeds within or across racks.

How do AOC Cables compare to traditional optical transceivers?
  • AOC cables: Integrate transceivers and cables into a single unit, reducing costs and simplifying installation. However, they’re fixed-length and less flexible for rewiring.
  • Transceivers: Require separate cables, offering more flexibility but higher costs and maintenance due to exposed optical interfaces.
What lengths are available for AOC Cables?

AOC cable are available in lengths from 1 meter to 100 meters, with common lengths being 3m, 5m, 10m, 30m, and 50m. Custom lengths may be offered by Fibrecross.

How do I choose the right AOC Cable?

Consider:

  • Data Rate: Match the cable to your equipment’s speed (e.g., 40G, 100G).
  • Length: Select based on your setup’s distance requirements.
  • Form Factor: Ensure compatibility (e.g., QSFP+ or SFP28).
  • Protocol: Verify support for Ethernet, InfiniBand, etc.
  • Environment: Account for EMI or cable management needs.
What should I do if my AOC Cable isn’t working?
  • Confirm compatibility with your equipment.
  • Check that connectors are securely plugged in.
  • Verify the cable length is within specifications.
  • Test with another port or device to isolate the issue.
  • Contact your supplier for support or replacement.
