## Summary description

BlueOptics Atto CBL-0130-001 is a QSFP twinaxial Direct Attach Cable (DAC) rated for 40Gbps. Designed for short-reach connectivity between network devices with QSFP ports, it provides a fixed, low-latency copper link ideal for switches, servers and storage in data centers and rack-to-rack connections. Passive construction suits environments where cost-effective, high-bandwidth interconnects are required.

## Long description

BlueOptics Atto CBL-0130-001 is a QSFP twinaxial Direct Attach Cable (DAC) engineered for 40Gbps short‑reach connections. The cable provides a fixed copper link between QSFP ports on switches, servers and storage devices, delivering low latency and predictable performance for data center and rack‑to‑rack interconnects. Its passive construction makes it a cost‑effective solution where high bandwidth over short distances is required.
Advantages
The Direct Attach Cable delivers native 40Gbps throughput with minimal signal conversion, reducing latency compared with optical transceivers and separate fiber assemblies. Being a factory‑terminated twinaxial assembly, it eliminates the need for additional connectors or transceivers, simplifying deployment and reducing total system cost. The robust QSFP housing and cable design ensure reliable electrical contact and consistent impedance for stable performance in dense networking environments.
Suitable for
 Short‑reach connections between switches within a rack or between adjacent racks
 Direct server-to-switch or server-to-storage links requiring 40Gbps bandwidth
 High-density top-of-rack and spine-leaf network deployments in data centers
Key specifications
 Interface: QSFP (Quad Small Form‑factor Pluggable) twinaxial direct attach
 Data rate: 40 Gbps aggregate
 Cable type: Passive twinax copper assembly
 Typical use case: Short‑reach, rack‑to‑rack and intra‑rack interconnects
 Connector housing: QSFP form factor for direct plug‑in to QSFP ports
How to use
Insert each QSFP connector end into the corresponding QSFP port on the two network devices until the connector latches. Verify that device port LEDs indicate a proper link and that network interfaces are configured for 40Gbps operation if required by the equipment. For removal, press the latch mechanism and withdraw the connector straight out to avoid stress on the cable or port. Handle the cable by the connector housings and avoid tight bends at the connector transition to maintain signal integrity.
Usage recommendations
Use the DAC for connections within the specified short‑reach distance supported by QSFP passive twinax assemblies; avoid routing through patch panels or across excessive lengths. Ensure airflow and cable management practices in the rack do not compress or sharply bend the cable near connectors. Confirm compatibility with the QSFP ports on your switches and servers by checking supported link speeds and passive DAC support in device documentation.
