## Summary description

CBO CBL-405-BO is a 5-meter QSFP to QSFP cable that supports 40 Gbit/s data rates with QSFP male connectors on both ends. Designed for short-reach high-speed interconnects between switches, servers and network devices, it provides a simple direct-attach solution without transceivers. Use cases include rack-to-rack links, top-of-rack switch connections and high-density data center cabling.

## Long description

CBO CBL-405-BO is a 5 m direct-attach QSFP to QSFP active cable engineered for 40 Gbit/s short-reach connections. With QSFP male connectors on both ends, this cable provides a straightforward, low-latency link between high-density network devices without the need for separate transceivers. It is intended for rack-to-rack links, top-of-rack switch connections and other data centre cabling where compact, reliable 40 Gbit/s interconnects are required.
Advantages
The active design improves signal integrity over the 5 m length while keeping power consumption and insertion loss low. QSFP male-to-male connectors simplify installation and reduce component count by eliminating separate optical or electrical transceivers. The cable supports full 40 Gbit/s aggregated throughput, enabling high-throughput traffic between switches, servers and storage appliances. Its form factor is compatible with standard QSFP ports and high-density switch panels.
Suitable for
 Rack-to-rack 40 Gbit/s links in data centres
 Top-of-rack switch connections
 Short-reach server-to-switch interconnects
 High-density networking panels and blade chassis
Key specifications
 Nominal length: 5 metres
 Supported data rate: 40 Gbit/s
 Connector type: QSFP male to QSFP male
 Cable type: active direct-attach cable (DAC)
 Typical use: short-reach high-speed interconnect
How to use
Verify that both devices have compatible QSFP ports and that the switch or server supports direct-attach QSFP active cables at 40 Gbit/s. With devices powered down or ports inactive if required by your maintenance procedure, insert each QSFP male connector into the corresponding QSFP socket until it latches. Enable or configure the ports in the network device management interface according to your network plan and verify link status and speed. If needed, perform basic diagnostics such as link LEDs, port counters and switch logs to confirm stable operation.
Usage recommendations
Route the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius specified by the equipment vendor. Use the 5 m length for direct short links inside racks or between adjacent racks; for longer distances consider active optical solutions. Keep firmware and port settings consistent across devices to ensure proper negotiation at 40 Gbit/s.
