AOC CBO QSFP28-100G-AOC-5M active optical cable QSFP28 100G 5 m

The AOC CBO QSFP28-100G-AOC-5M active optical cable is a 5-metre QSFP28 100G interconnect designed for high-density data center and enterprise networking environments. This plug-and-play cable establishes a fixed 100 Gigabit Ethernet link between compatible QSFP28 ports on switches, routers and network interface cards, offering a compact alternative to separate transceivers and fibre patchcords. Its integrated optical transceivers eliminate the need for additional modules and simplify cabling for short-reach connections.

Advantages

This active optical cable delivers full-duplex 100G throughput with low latency and consistent signal quality over a 5 m reach. The integrated design reduces power consumption and frees up front-panel space compared with pluggable transceiver plus fibre assemblies. Being hot-pluggable and vendor-compatible with QSFP28 ports, it simplifies installation and maintenance while providing predictable performance for demanding network fabrics.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections in data centers
• High-density top-of-rack aggregation and spine-leaf architectures
• Connecting 100G network interface cards (NICs) to switches or routers
• Environments where reduced power, space savings and simplified cabling are priorities

Key specifications

• Interface: QSFP28 to QSFP28 compatible
• Nominal bandwidth: 100 Gigabit per second (full duplex)
• Cable type: Active optical cable with integrated transceivers
• Length: 5 metres
• Typical reach: short-reach campus and data centre links
• Connector form factor: QSFP28 compliant housing
• Latency: low, suitable for high-performance Fabrics

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your networking devices until the latch engages. Ensure both devices support QSFP28 100G links and that firmware or driver compatibility is met where required. The module is hot-pluggable; devices will typically negotiate the link automatically. Verify link status and performance via the switch or NIC management interface after installation.

Usage recommendations

For reliable operation, route the cable to avoid tight bends and excessive torsion; observe the manufacturer’s minimum bend radius. Use the 5 m active optical cable for intra-rack or short inter-rack connections where 100G density is needed. Confirm QSFP28 compatibility with your hardware and keep device firmware updated to ensure full interoperability.
