Suitable for rack‑to‑rack or intra‑rack interconnects.

## Long description

CBO DAC QSFP-4X10G-C3M is a 3-meter direct attach copper cable with QSFP connector supporting four independent 10 Gbps channels. It is designed for short-reach, high-density connections in data center environments, providing a low-latency, energy-efficient link between switches, servers and storage systems without the need for separate optical transceivers. The cable is suitable for rack-to-rack and intra-rack interconnects where reliable 40 Gbps aggregate bandwidth and simple deployment are required.
Advantages
The direct attach copper construction delivers consistent electrical performance across four 10 Gbps lanes while minimizing power consumption compared with active optical solutions. The QSFP connector provides a compact, hot-pluggable interface that simplifies installation and replacement. With a fixed 3 m length, the cable reduces signal management complexity and supports high-density port layouts commonly found in modern server racks and network switches.
Suitable for
Short-reach 40 Gbps links between top-of-rack or leaf switches and aggregation equipment
Server-to-switch connections within the same rack or adjacent racks
Storage array interconnects requiring low latency and stable throughput
High-density data center environments where cost and power efficiency are priorities
Key specifications
Connector type: QSFP (Quad Small Form-factor Pluggable)
Aggregate bandwidth: 40 Gbps (4 × 10 Gbps lanes)
Length: 3 meters
Media: Direct attach copper (passive copper cable)
Typical use: Short-reach, rack-to-rack or intra-rack interconnects
Design: Hot-pluggable, high-density compatible
How to use
Insert each QSFP connector into the QSFP ports on the devices to be linked, ensuring the latch engages securely. Avoid excessive bending or twisting of the cable; follow the minimum bend radius guidelines of the equipment. No external power or transceivers are required. For best performance, verify that both endpoints support 4×10 Gbps lanes and configure link settings on the connected devices according to vendor recommendations.
Usage recommendations
Install the cable in organized cable runs and avoid routing near high-power electrical sources to reduce electromagnetic interference. For long-term reliability, keep the connectors clean and handle the cable by the booted connector area when plugging or unplugging.
