## Summary description

The BlueOptics X66120-1-BL is a 1 m InfiniBand/fibre optic cable featuring a QSFP connector and 4 x SFP+ connectors. It is designed for high-speed data transmission in data centers and networking applications. This cable ensures reliable performance and efficient connectivity for your devices.

## Long description

The BlueOptics X66120-1-BL is a 1 m InfiniBand/fibre optic direct attach cable with a QSFP plug on one end and four SFP+ connectors on the other. Designed for short-reach high-speed connections, this cable supports 40GBase-CR4 and 4x10GBASE-CR applications and provides a reliable copper twinax link between switches, routers, storage systems and other rack-mounted equipment. The passive design and 30 AWG construction follow MSA guidelines for compatibility with major hardware platforms that accept QSFP-to-4xSFP+ direct attach assemblies.
Advantages
This 1 m QSFP to 4 x SFP+ cable offers low latency and low power consumption due to its passive twinax construction, making it suitable for dense rack and adjacent-rack connections. It is manufactured to MSA-compliant specifications and assembled from high-quality components to deliver consistent electrical performance for Ethernet, FCoE, Fibre Channel and InfiniBand traffic up to 40 Gbit/s over the specified distance. The compact form factor and integrated connectors simplify installation and reduce points of failure compared with multiple separate patch cables.
Suitable for
Connecting QSFP ports to multiple SFP+ ports within racks and between adjacent racks
40GBase-CR4 direct attach applications and 4x10GBASE-CR aggregated links
High-density data centre top-of-rack and spine-leaf topologies
Short-distance links for switches, routers, and storage arrays supporting QSFP/ SFP+ interconnects
Key specifications
Cable length: 1 metre
Connector configuration: QSFP to 4 × SFP+
Transmission types supported: 40GBase-CR4 and 4×10GBASE-CR
Cable type: passive twinax copper, 30 AWG
Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 40 Gbit/s over 1 m)
Form factor: direct attach cable (DAC) for short-reach connections
How to use
Insert the QSFP connector into the QSFP port on the source device and plug each SFP+ connector into the corresponding SFP+ ports on the target device or patch panel. Ensure both devices support passive QSFP-to-4xSFP+ direct attach cables and the intended transmission protocol (for example 40GBase-CR4 or 4x10GBASE-CR). Route the cable to avoid sharp bends; maintain minimum bend radius recommended for twinax cables to preserve signal integrity. No external power or transceivers are required for passive operation.
Usage recommendations
Use this cable for short-distance, high-throughput links within racks or between adjacent racks. Verify hardware compatibility and firmware settings before deployment, and perform link validation after installation. For longer distances or active optical requirements, choose appropriate active DACs or optical transceivers and fibre cables.
