## Summary description

The BlueOptics QFX-SFP-DAC-3M-BL is a 3-meter SFP+ cable designed for high-speed data transmission. It features male connectors on both ends, ensuring compatibility with various devices. Ideal for connecting switches, routers, and servers in data centers or network environments.

## Long description

The BlueOptics QFX-SFP-DAC-3M-BL is a 3 meter SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends, designed for short-distance 10 Gbit/s links in racks and between adjacent racks. This passive twinax copper cable implements 10GBase-CR electrical signaling over 30 AWG conductors and follows MSA guidelines for SFP+ interoperability. It is suitable for connecting switches, routers, servers and storage systems that support 10G SFP+ DAC connections and is offered in a black/silver housing with a lightweight construction (approximately 0.13 kg).
Advantages
The cable provides a low-latency, low-power (passive) connection for high-speed links up to 10 Gbit/s over a fixed 3 m distance, avoiding the need for separate transceivers and fiber patching for short runs. Compliance with MSA and the use of standard SFP+ connectors ensure broad compatibility with major hardware platforms that accept SFP+ direct attach copper. Its twinax copper design and passive operation result in simple installation, reduced failure rate and predictable electrical performance for data center top-of-rack and adjacent-rack connections.
Suitable for
Top-of-rack and adjacent-rack 10G interconnects in data centers
Direct server-to-switch or switch-to-switch links supporting 10GBase-CR
Storage systems and SAN connections using 10G Ethernet, FCoE or Fibre Channel over supported platforms
Short-distance high-bandwidth links where low latency and low power are important
Key specifications

Length: 3 meters
Transmission rate: up to 10 Gbit/s (10GBase-CR)
Cable type: passive twinax copper, 30 AWG
Compliance: MSA-compliant for SFP+ interoperability
Applicable protocols: Ethernet, FCoE, Fibre Channel (where supported by hardware)
Colour: black and silver
Weight: approx. 0.13 kg
How to use
Install the BlueOptics QFX-SFP-DAC-3M-BL by inserting each SFP+ module end into SFP+ ports of the devices to be linked (for example, switch-to-switch or server-to-switch). Ensure both devices support passive SFP+ direct attach copper cables and the same transmission protocol (10GBase-CR or equivalent). Verify port settings and link status in device management interfaces after insertion. For initial deployment, power down or follow hot-plug guidelines of the equipment vendor if recommended; in most modern network devices SFP+ DACs support hot-plug insertion.
Usage recommendations
Use this 3 m passive DAC for short rack-to-rack or within-rack connections where cable length is known and within the 3 m limit. Verify vendor compatibility with passive SFP+ DACs in your switch or server documentation before purchase and test a sample cable in your environment if required.
