## Summary description

The BlueOptics X66120-3-BL is a 3 m InfiniBand fibre optic cable featuring a QSFP connector and four SFP+ connectors. Designed for high-speed data transmission, it ensures reliable connectivity in data centers and networking environments. The male/male configuration allows for easy installation and compatibility with various devices, making it an ideal choice for enhancing network performance.

## Long description

The BlueOptics X66120-3-BL InfiniBand fibre optic cable is a 3 m direct attach solution with a QSFP plug on one end and four SFP+ plugs on the other. Designed for short-reach, high-throughput links, this passive twinax-style cable supports 40GBase-CR4 or 4x10GBase-CR operation and is intended for use in rack and adjacent-rack connections where low latency and high availability are required. The cable follows MSA electrical and mechanical guidelines to ensure interoperability with compatible network switches, storage systems and host adapters that accept QSFP-to-4xSFP+ breakout assemblies.
Advantages
This 3 m cable offers a compact, low-power connection option for high-density network environments. Its QSFP to 4xSFP+ male/male configuration enables direct breakout from a 40 Gbps port into four 10 Gbps links without intermediate transceivers. As a passive copper/twinax-style direct attach solution, it provides low latency and minimal power consumption and is manufactured using industry-grade components to deliver consistent electrical performance for short-distance interconnects.
Suitable for
 High-density rack-to-rack or intra-rack links in data centres
 Connecting QSFP ports to multiple SFP+ ports for server, switch or storage interconnects
 40GBase-CR4 and 4x10GBase-CR passive breakout applications
 Environments where low latency and low power consumption are priorities
Key specifications
 Cable length: 3 metres
 Connector type: QSFP (one end) to 4 × SFP+ (other end), male/male
 Supported data rates: up to 40 Gbps aggregate (4 × 10 Gbps lanes)
 Cable type: passive direct attach (twinax-style) suitable for short-reach electrical signalling
 Wire gauge: 30 AWG conductor specification for short-distance high-speed links
 Compliance: designed to meet MSA electrical/mechanical breakout DAC guidelines and common industry standards
How to use
Install the BlueOptics X66120-3-BL by inserting the QSFP connector into the 40G-capable QSFP port and inserting each SFP+ connector into the corresponding 10G-capable SFP+ ports. Ensure that both ends are fully seated and that connected devices are powered down or follow hot-plug guidance per the device manufacturer. Verify that the host ports and firmware support passive QSFP-to-4xSFP+ breakout operation and confirm link status through the equipment management interface after connection.
Usage recommendations
Use this cable for short-distance links within or between adjacent racks; avoid extending beyond the intended 3 m range for reliable signal integrity. Confirm device compatibility and firmware support for passive breakout DACs before deployment. Store and route the cable without sharp bends and avoid mechanical strain on connectors to maintain long service life.
