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

BlueOptics BO282803L5M is an active optical cable (AOC) with QSFP28 connectivity designed for 100G Ethernet links at a fixed 5 m length. The cable provides a compact, low-power alternative to copper for short-reach connections inside racks, between adjacent racks or within rows in data centers. Using optical transmission reduces electromagnetic interference and supports high-density server and switch interconnects where cable management and thermal performance matter.

Advantages

This QSFP28 100G active optical cable delivers high data throughput with lower power consumption compared to equivalent copper solutions. The optical medium reduces susceptibility to electromagnetic interference and crosstalk, enabling more stable links in dense environments. Its factory-terminated QSFP28 interfaces simplify installation and ensure consistent signal quality while the 5 m fixed length eliminates the need for field termination and minimizes excess cabling.

Suitable for

• Short-reach 100G connections between switches in the same rack
• Server-to-switch links in high-performance computing and storage environments
• Within-cabinet and adjacent-rack data center interconnects
• High-density patching panels and top-of-rack deployments

Key specifications

• Connector type: QSFP28 duplex optical interface
• Data rate: 100 Gbit/s
• Length: 5 metres (fixed)
• Cable type: active optical cable (AOC)
• Transmission medium: multimode optical fiber with integrated transceivers
• Typical use: short-reach direct interconnect within racks and rows
• Electrical characteristics: low power consumption compared to equivalent copper twinax solutions

How to use

Install the AOC by inserting the QSFP28 connector into compatible QSFP28 ports on switches, routers or servers. Ensure both endpoints support 100G operation and that port settings (speed, lane mapping, and auto-negotiation) are configured according to the host devices’ documentation. Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s recommended bend radius. For hot-pluggable systems, the cable can be inserted or removed while equipment is powered, but follow your equipment vendor’s hot-swap guidelines to avoid link disruptions.

Recommendations

Use this 5 m active optical cable for short, fixed-length links where optical immunity to interference and reduced power draw are priorities. Verify QSFP28 port compatibility and firmware support on both devices before deployment, and keep cable runs free from excessive bending or kinking to preserve signal integrity and service life.
