## Summary description

CBO CBL-QSFP-40GE-PASS-2M is a 2-meter passive DAC (direct-attach copper) cable with QSFP+ connectors supporting 40GbE links. Designed for short-range server, switch and storage interconnects, it provides a low-latency, low-power physical connection without separate transceivers. Suitable for top-of-rack and aggregation use where cost-effective, reliable 40GbE connectivity is required.

## Long description

CBO CBL-QSFP-40GE-PASS-2M is a 2‑metre passive DAC (direct-attach copper) cable with QSFP+ connectors that supports 40GbE links. It is intended for short-reach connections between servers, switches and storage devices where a direct copper connection minimizes latency and power consumption. The cable is a factory-terminated solution that eliminates the need for separate optical transceivers, simplifying rack-level cabling for top-of-rack and aggregation deployments.
Advantages
The passive QSFP+ to QSFP+ assembly offers low electrical latency and minimal power draw compared with active optics or transceiver-based links. Its 2 m length provides a predictable signal path suitable for intra-rack and short inter-rack connections. As a direct-attach copper solution it reduces component count and total cost of ownership for high-density 40GbE environments, while maintaining compatibility with standard QSFP+ ports and link speeds.
Suitable for
Short-range server-to-switch connections within racks
Top-of-rack and aggregation switch interconnects
High-density switch-to-switch links in data centres
Storage array connections requiring 40GbE bandwidth
Key specifications
Cable type: passive direct-attach copper (DAC)
Connector type: QSFP+ to QSFP+
Nominal data rate: 40 Gigabit Ethernet (40GbE)
Length: 2 metres
Typical use range: short-reach, intra-rack and close inter-rack
Power profile: passive (no active electronics in cable)
How to use
Insert each QSFP+ plug into the corresponding QSFP+ port on the two devices to be connected, ensuring the latch engages and the module is fully seated. Verify link negotiation on both endpoints and confirm 40GbE operation via device management interfaces. Handle the cable by its connectors and avoid sharp bends; maintain the specified bend radius and secure excess cable to prevent strain on the plugs. If the link does not come up, check port configuration and compatibility with passive DAC modules on the equipment.
Usage recommendations
Use this 2 m passive DAC for short-distance connections where low latency and low power consumption are priorities. Avoid using passive copper assemblies for distances beyond the recommended intra-rack and nearby inter-rack ranges; for longer runs, consider active DACs or optical transceivers with fiber cabling. Ensure device port compatibility with passive QSFP+ cables and consult switch vendor documentation for any required settings or supported cable lists.
