AOC CBO BlueOptics QSFP28 BO282803L5M 100G active optical cable 5 m

The AOC CBO BlueOptics QSFP28 BO282803L5M 100G active optical cable 5 m is a multimode fiber link engineered for 100 Gigabit Ethernet environments. It uses a QSFP28 connector on each end to provide a direct, high-bandwidth connection between servers, switches or other data‑center devices over a 5‑meter distance. The active optical design reduces electromagnetic interference and power loss compared with equivalent copper cables while supporting high-speed, low-latency data transmission in dense networking racks.

Advantages

This active optical cable offers stable 100G throughput with low insertion loss and improved signal integrity across the 5 m multimode span. The QSFP28 form factor enables compact, high-density port utilization in switches and servers. Because the cable is optical and active, it reduces susceptibility to EMI and crosstalk and typically consumes less power than longer copper DAC alternatives. The plug-and-play design requires no additional transceivers or fiber termination, simplifying installation and maintenance.

Suitable for

• Direct server-to-switch or switch-to-switch 100G connections in data centers
• Top-of-rack and spine-leaf network architectures requiring short-reach 100G links
• High-density switch panels where QSFP28 ports are used

Key specifications

• Data rate: 100 Gigabit per second
• Cable type: Active optical multimode
• Connector type: QSFP28 on both ends
• Nominal length: 5 meters
• Typical application: Short-reach data center interconnects
• Benefits: Low electromagnetic interference and improved signal integrity compared with copper

How to use

Install the cable by inserting each QSFP28 connector into the matching QSFP28 port on your network devices until the latch engages. Ensure ports are powered and compatible with 100G QSFP28 modules or host adapters. No additional transceivers or fiber patching are required. Verify link status and interface settings on connected equipment and update firmware or driver settings if necessary to enable full 100G operation. Handle the cable by the connector boot and avoid tight bends to maintain optical performance.

Recommendations

For reliable operation, route the cable away from high-heat sources and maintain a bend radius consistent with manufacturer guidelines. Use the AOC for short-reach 100G links inside racks and between adjacent racks; for longer distances, consider optical transceivers with appropriate fiber types. Confirm QSFP28 port compatibility with your switch or server vendor documentation before deployment.
