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

AOC BlueOptics QSFP28 BO282803L5M is an active optical cable providing 100G connectivity over a 5 m duplex optical link. The QSFP28 form-factor cable is designed for short-reach multimode transmission in data centers and network racks, delivering a plug-and-play solution for switch-to-switch, server-to-switch and storage interconnects. The cable reduces electromagnetic interference compared with copper alternatives and supports low-latency high-bandwidth links suitable for modern 100G network architectures.

Advantages

The active optical construction enables high-speed 100G transmission with lower power dissipation and longer reach than equivalent copper direct attach cables. Multimode optics provide stable short-reach performance while minimizing crosstalk and EMI. The QSFP28 connector housing ensures compatibility with QSFP28 ports and simplifies installation with hot-pluggable operation. The 5 m duplex length is optimized for intra-rack and adjacent-rack connections without excess cable slack.

Suitable for

• Data center switch-to-switch uplinks and spine-leaf architectures
• Server-to-switch 100G connections in high-performance computing racks
• Storage array interconnects requiring short-reach 100G links
• Top-of-rack and adjacent-rack cabling where reduced EMI is required

Key specifications

• Interface: QSFP28 to QSFP28 duplex
• Data rate: 100 Gbit/s
• Cable type: Active optical cable (AOC), multimode
• Length: 5 meters
• Form factor: QSFP28 compatible transceiver housing
• Typical use: Short-reach intra-rack and adjacent-rack links

How to use

Ensure both network devices support QSFP28 100G ports and are powered off or in a stable state for hot-plug operations as required by your equipment. Align the QSFP28 connector with the port and insert until it latches; repeat for the second end. After connection, verify link status via the switches or servers management interface and confirm 100G speed negotiation. Route the 5 m cable to avoid tight bends and mechanical stress; maintain recommended bend radius for optical assemblies and secure excess cable to prevent accidental disconnection.

Recommendations

For optimal performance, use this 5 m AOC for intra-rack or adjacent-rack 100G links and avoid mixing with long passive copper runs. Keep connectors clean and inspect ends before insertion; follow equipment vendor guidelines for transceiver compatibility and firmware settings to ensure stable 100G operation.
