## Summary description

The BlueOptics X4DACBL1-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 and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics X4DACBL1-BL InfiniBand fibre optic cable is a 1 m direct-attach solution with a QSFP plug on one end and four SFP+ plugs on the other. Designed for short-reach high-speed links, the cable supports up to 40 Gbps aggregate throughput using a QSFP to 4×SFP+ breakout configuration and is intended for rack and adjacent-rack interconnects in data center and networking environments.
Advantages
This 1 m QSFP to 4×SFP+ cable provides a compact, low-latency connection that requires no active components when used with hardware that supports passive direct-attach copper/twinax interconnects. The assembly is produced to Multi-Source Agreement (MSA) guidelines and is compatible with systems supporting QSFP breakout to SFP+ ports. The cable offers low power usage, predictable signal performance for Ethernet, FCoE and InfiniBand applications up to 40 Gbps aggregate, and is built from industry-grade components to achieve an extended operational lifetime.
Suitable for / Применение / Piemērots
High-density switch-to-switch and switch-to-server connections in racks
Short-distance links between adjacent racks or within rack enclosures
40GBase-CR4 and 4×10GBase-CR environments where QSFP-to-4×SFP+ breakout is required
Environments using Ethernet, FCoE, Fibre Channel or InfiniBand protocols
Key specifications
Cable length: 1 metre
Connector type: QSFP (one end) to 4 × SFP+ (other end)
Aggregate data rate: up to 40 Gbps (QSFP breakout to 4×10 Gbps lanes)
Cable type: direct-attach passive twinax (suitable for short reaches)
Wire gauge (typical): 30 AWG
MSA-compliant mechanical and electrical interface
Suitable for Ethernet, FCoE, Fibre Channel and InfiniBand applications
How to use
Install the cable by inserting the QSFP connector into a QSFP port and each SFP+ connector into the target SFP+ ports on the remote device. Ensure both devices support passive QSFP-to-4×SFP+ direct-attach connections and the same protocol speeds (for example QSFP configured as 4×10 Gbps lanes for 40GBase-CR4 or 4×10GBase-CR). Avoid bending the cable sharply near the connectors and route it to prevent strain on the plugs. Verify link status and negotiated speeds in the device management interface after connection.
Usage recommendations
Use this direct-attach cable for short-reach, high-bandwidth links where low latency and low power consumption are priorities. Confirm compatibility with your switch, router or storage hardware and consult vendor documentation if passive DAC support or specific QSFP breakout configuration is required.
