## Long description

The BlueOptics JG331A-BL is a 5 m direct-attach twinax cable with a QSFP connector on one end and four SFP+ connectors on the other, designed for male-to-male connections. It supports aggregated 40G links using a 40GBase-CR4 / 4x10GBASE-CR breakout topology and is intended for short-range electrical connections inside racks or between adjacent racks. The cable is a passive twinax copper assembly with 26 AWG conductors and a black outer jacket for standard datacentre installations.
Advantages
This BlueOptics passive DAC provides low latency and low power consumption compared with active optical modules. Being MSA-compliant, it follows industry-defined mechanical and electrical interfaces for QSFP-to-4xSFP+ breakout use and is compatible with systems that support equivalent HPE JG331A-style breakout cables. The cable’s construction uses robust materials to deliver reliable signal integrity over the specified 5 m distance and a long service lifetime when used within recommended conditions.
Suitable for
40G to 4x10G breakout connections between QSFP ports and multiple SFP+ ports
Short-reach links inside server racks or between adjacent racks
Switch-to-switch, switch-to-router or switch-to-storage connections supporting 40GBase-CR4 / 4x10GBASE-CR
InfiniBand, Ethernet, FCoE or Fibre Channel applications at supported speeds over 5 m
Key specifications
Cable length: 5 m
Connector configuration: QSFP to 4 × SFP+
Cable type: Passive twinax (direct attach copper)
Conductor gauge: 26 AWG
Colour: Black
Typical use: 40GBase-CR4 / 4×10GBASE-CR breakout
Weight: 0.25 kg
How to use
Ensure both devices support passive QSFP-to-4xSFP+ breakout cables and the intended transmission protocol (e.g., Ethernet, InfiniBand, FCoE) before installation. With both devices powered down or as recommended by the equipment vendor, insert the QSFP plug into the QSFP port and the four SFP+ plugs into the corresponding SFP+ ports. Secure the connectors by seating them fully until the retention latches engage. After installation, verify link status and negotiated speeds in the host equipment management interface.
Usage recommendations
Use this cable for short-distance, high-bandwidth interconnects where passive twinax is supported. Avoid tight bends, excessive pulling force, and installation near strong EMI sources. Confirm vendor compatibility for passive DACs in your hardware to ensure proper operation and to preserve warranty and support terms.
