CBO QSFP AA1404001-E6-BO 40 Gbps Copper Transceiver Module

The CBO QSFP AA1404001-E6-BO 40 Gbps Copper Transceiver Module is a compact QSFP form-factor module engineered for short-reach copper interconnects. It aggregates four 10 Gbps lanes into a single 40 Gbps link and is intended for use in equipment that supports QSFP copper modules. The module offers a plug-and-play interface for high-throughput links between switches, routers and network appliances in data centre and enterprise environments.

Advantages

This transceiver provides four-lane aggregation to deliver 40 Gbps bandwidth over copper, enabling high-density connectivity without fiber cabling. Its QSFP form factor supports hot-pluggable installation into compatible ports and reduces port hardware complexity by consolidating multiple 10 Gbps channels. Built for short-reach copper links, the module simplifies cabling and can lower overall link cost where fiber is not required.

Suitable for

• Short-reach interconnects between switches and routers in data centres
• Top-of-rack and aggregator switch connections
• Server-to-switch high-throughput links within racks
• Lab, testing and development environments requiring 40 Gbps copper links

Key specifications

• Aggregate data rate: 40 Gbps (four lanes of 10 Gbps)
• Form factor: QSFP (quad small form-factor pluggable)
• Media type: Copper twinax or compatible copper cabling for short-reach links
• Interface: Hot-pluggable electrical QSFP connector
• Typical use case: Short-reach direct attach copper connections

How to use

Install the module into a compatible QSFP port on a switch, router or network adapter while the host is powered per vendor guidance for hot-pluggable modules. Connect the appropriate copper twinax cable between the module and the corresponding QSFP port on the peer device, ensuring secure seating of connectors at both ends. Verify link status and lane aggregation in the host equipment management interface and confirm operating speed at 40 Gbps after link negotiation.

Recommendations

Use certified copper twinax cables of appropriate length for short-reach connections and verify compatibility with the host equipment. Monitor port temperatures and link diagnostics in high-density deployments to ensure stable operation. For longer distances or environments requiring electrical isolation, consider fiber-based QSFP options instead of copper.
