BlueOptics QSFP28 Active Optical Cable BO282803L3M 3 m

BlueOptics QSFP28 Active Optical Cable BO282803L3M is a 3 m high-speed interconnect designed for 100G links between switches, routers and servers equipped with QSFP28 ports. The active optical design converts electrical signals to optical and back, enabling longer reach and lower latency than equivalent copper assemblies. The cable reduces electromagnetic interference and simplifies cabling in dense rack and data center environments while remaining a plug-and-play solution for short to medium range connections.

Advantages

The active optical cable offers a compact, lightweight form factor with improved signal integrity over longer distances compared to copper. It supports 100G data rates with low insertion loss and minimal crosstalk, helping maintain line-rate performance. Its QSFP28 interfaces ensure hot-pluggable installation and compatibility with standard 100G QSFP28 ports. The optical medium reduces susceptibility to electromagnetic interference and eliminates the need for complex shielding and grounding associated with copper alternatives.

Suitable for

• 100G interconnects between network switches in data centers
• High-speed links between routers and aggregation devices
• Server-to-switch connections in top-of-rack and end-of-row deployments
• Short- to medium-reach optical links where low latency and EMI immunity are required

Key specifications

• Connector type: QSFP28 to QSFP28
• Cable type: Active Optical Cable (AOC)
• Supported data rate: 100 Gbit/s
• Length: 3 meters
• Form factor: Compact, lightweight optical assembly
• Latency: Low-latency optical transmission suitable for line-rate applications
• EMI performance: Immune to electromagnetic interference compared to copper

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding port on the network devices until the latch engages. The cable is plug-and-play and typically requires no additional configuration; the host devices detect the link and negotiate 100G operation automatically. Route the cable to avoid tight bends and sharp edges, and ensure the length and port details match the intended topology. For best results, follow equipment vendor recommendations for QSFP28 interoperability and firmware compatibility.

Usage recommendations

Use this 3 m active optical cable for short- to medium-length 100G connections within racks or between adjacent racks. Avoid excessive bending radii and exposure to mechanical strain. Verify compatibility with your switch and server QSFP28 ports and update device firmware if needed to ensure full 100G operation.
