## Summary description

The BlueOptics QSFP-DAC-2M-BL is a 2-meter QSFP to QSFP direct attach copper cable designed for high-speed data transmission. It features male connectors on both ends, ensuring a secure connection for networking equipment. Ideal for data centers and high-performance computing environments, this cable offers reliability and efficiency in data transfer.

## Long description

The BlueOptics QSFP-DAC-2M-BL is a 2‑meter QSFP to QSFP direct attach copper cable designed for 40G high-speed links in racks and between adjacent racks. This passive twinax cable uses 30 AWG conductors and QSFP male connectors on both ends, follows MSA guidelines and supports electrical 40GBase-CR4 transmission for short-range connections. It is intended for use in switches, routers, storage systems and other network devices that accept QSFP DAC modules and support 40 Gbit/s protocols such as Ethernet, FCoE, Fibre Channel and InfiniBand.
Advantages
The cable provides a low-latency, low-power direct attach solution with passive operation that does not require active electronics. Manufacturer-grade components and MSA-compliant design ensure mechanical compatibility, reliable signal integrity and long service life. The fixed 2 m length simplifies rack planning for short links and reduces the need for additional transceivers and fiber infrastructure, offering a cost-effective option for dense data-center topologies.
Suitable for
 40G links between switches inside racks or between adjacent racks
 High-performance computing interconnects requiring low latency
 Direct attach connections for storage arrays and routers
 Environments that support passive QSFP DACs for Ethernet, FCoE or InfiniBand
Key specifications
 Cable type: QSFP to QSFP direct attach copper (twinax), passive
 Length: 2 meters
 Connector: QSFP male on both ends
 Data rate: up to 40 Gbit/s (40GBase‑CR4 compatible)
 Wire gauge: 30 AWG
 Standards: MSA-compliant mechanical/electrical interface
 Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand (short range)
How to use
Install the BlueOptics QSFP-DAC-2M-BL by inserting the QSFP connectors into the QSFP ports of the devices to be linked. Ensure both host devices explicitly support passive QSFP DACs and the 40GBase-CR4 electrical protocol. Handle the cable by the connector housings to avoid stress on the twinax assembly and follow standard ESD precautions when connecting hardware. No external power or configuration is required for passive operation; link negotiation and speed settings are managed by the connected devices according to their firmware and platform capabilities.
Usage recommendations
Use this 2 m DAC for short, direct rack-to-rack or intra-rack connections where passive twinax is supported. Verify device compatibility in device vendor documentation and firmware before deployment. Avoid sharp bends, excessive pulling force and exposure to high temperatures to maintain signal integrity and maximize service life.
