CBO QSFP-naar-QSFP-actiefkabel CBL-405-BO 5 m – 40 Gbit/s, QSFP stekker op stekker

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.

Key specifications

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.

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.
