## Summary description

The BlueOptics 02310MUL-BL is a 3 m InfiniBand/fibre optic cable featuring a QSFP connector and 4x SFP+ connectors. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics InfiniBand/fibre optic cable 3 m QSFP 4x SFP+ Black is a 3-metre direct-attach cable (DAC) with a QSFP connector on one end and four SFP+ connectors on the other. Designed for short-distance, high-speed interconnects in racks and between adjacent racks, this passive 40GBase-CR4 / 4x10GBASE-CR twinax cable supports InfiniBand, Ethernet, FCoE and Fibre Channel applications up to 40 Gbit/s over the 3 m length. The cable follows MSA guidelines and is intended for use in hardware platforms that support QSFP to 4xSFP+ passive DAC connections.
Advantages
This BlueOptics 3 m QSFP to 4xSFP+ cable offers a low-latency, low-power connection suitable for dense rack environments. As a passive twinax DAC it does not require additional power for transceivers and provides a cost-effective option for short-range links. The construction uses quality components and adheres to industry MSA standards to ensure compatibility with major switches, routers and storage systems that accept QSFP-to-SFP+ passive connections.
Suitable for
High-speed links between switches and top-of-rack devices in data centers
Server-to-switch and switch-to-switch connections over short distances (up to 3 m)
Applications using 40GBase-CR4 or aggregated 4×10GBase-CR lanes
InfiniBand, Ethernet, Fibre Channel and FCoE traffic in supported hardware
Key specifications
Cable type: passive twinax direct-attach cable (DAC)
Length: 3 metres
Connector configuration: QSFP (one end) to 4 × SFP+ (other end)
Data rate: supports aggregated 40 Gbit/s (4 × 10 Gbit/s lanes)
Wire gauge: 30 AWG twinax conductors
Use case: short-reach, rack-to-rack and intra-rack interconnects
How to use
Install the cable by inserting the QSFP plug into a compatible QSFP port and the SFP+ plugs into the corresponding SFP+ ports on connected devices. Ensure both devices support passive QSFP-to-4xSFP+ DACs and that ports are powered off or follow hot-plug recommendations of the hardware vendor during installation. Verify link status after connection and consult device documentation for lane mapping or port trunking configuration when using aggregated 4×10G lanes.
Usage recommendations
For reliable operation, route the cable to avoid tight bends and compressive forces; maintain minimum bend radius as specified by the rack or cable manufacturer. Use this 3 m passive DAC for short-distance, high-throughput interconnects where low latency and low power draw are priorities. Confirm compatibility with target hardware and firmware versions prior to deployment; request a test sample when compatibility needs to be validated in complex environments.
