## Summary description

The BlueOptics MCP7904-X002A-BL is a 3m InfiniBand fibre optic cable featuring QSFP and 4xSFP+ male connectors. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable performance and minimal signal loss.

## Long description

The BlueOptics MCP7904-X002A-BL InfiniBand Fibre Optic Cable 3m QSFP 4xSFP+ Male/Male is a 3-metre direct attach solution intended for short-range high-speed interconnects in server racks and adjacent rack connections. It provides a 40G multi-lane link using a QSFP to 4xSFP+ physical configuration and is suitable for Ethernet, InfiniBand and related high-throughput protocols when used in hardware that supports passive direct attach cabling.
Advantages
This 3m cable implements a QSFP to quad SFP+ connection designed to carry up to 40 Gbps aggregate throughput over a single assembly while keeping power consumption and latency low. The cable is manufactured to MSA-compliant form-factor standards and uses high-quality conductors and components to ensure signal integrity and long service life. Being a passive direct attach solution, it requires no external power or active transceivers in the cable itself, simplifying installation and reducing potential points of failure.
Suitable for
Short-distance interconnects between switches and servers within the same rack or adjacent racks
High-throughput links for storage systems and SAN fabrics
40G Ethernet or 4×10G breakout connections in InfiniBand and converged networks
Data centre top-of-rack and access layer connections where passive QSFP-to-4xSFP+ cabling is supported
Key specifications
Connector type: QSFP (one end) to 4×SFP+ (other end), male-to-male
Length: 3 metres
Aggregate data rate: up to 40 Gbps (4×10 Gbps lanes)
Cable type: passive direct attach twinax copper compatible with 30 AWG wiring
Form-factor compliance: MSA-compliant QSFP and SFP+ mechanical profiles
Typical applications: Ethernet, InfiniBand, FCoE and Fibre Channel over short distances
How to use
Install the cable by inserting the QSFP plug into the QSFP port of the host device and each SFP+ plug into the respective SFP+ ports of the target device or breakout module. Ensure devices are powered down or individual ports are administratively disabled if required by your hardware vendor before insertion or removal. Verify that the connected equipment supports passive QSFP-to-4xSFP+ direct attach assemblies and that port speeds and link aggregation settings are configured to match the intended 40G or 4×10G operation.
Usage recommendations
Use this cable for short, rack-level connections only; avoid routing over long conduit paths or exposure to sharp bends that exceed the manufacturer’s minimum bend radius. Confirm compatibility with the switch, router or HBA vendor firmware and port settings before deployment, and perform link testing after installation to validate signal integrity and negotiated link speeds.
