## Summary description

The BlueOptics 49Y7886-BL is a 1 m InfiniBand/fibre optic cable featuring a QSFP connector and 4xSFP+ connectors. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics 49Y7886-BL is a 1 m InfiniBand / fibre optic direct attach cable with a QSFP connector on one end and four SFP+ connectors on the other. Designed for short-reach, high-speed links in racks and between adjacent racks, this cable supports 40GBase-CR4 and 4×10GBase-CR electrical transmission and is compatible with hardware platforms and transceivers that accept QSFP-to-4×SFP+ DAC connections. The cable is a passive twinax copper type with 30 AWG conductors and follows MSA guidelines for form factor and signal mapping.
Advantages
This 1 m QSFP-to-4×SFP+ cable provides a compact, low-latency connection for short-distance interconnects in data centers. As a passive direct attach cable it requires no additional power or active electronics for standard 10G lane operation, reducing power consumption and heat generation. The design complies with industry MSA specifications and uses high-quality components to ensure reliable signal integrity and consistent performance in Ethernet, FCoE and InfiniBand environments up to 40 Gbit/s over the specified distance.
Suitable for
High-density switch-to-switch links inside racks
Server-to-switch and storage-to-switch short-reach connections
Aggregation ports that require QSFP to multiple SFP+ lanes
Environments using 40GBase-CR4 or 4×10GBase-CR electrical interfaces
Key specifications
Cable length: 1 metre
Connector types: QSFP (one end) to 4×SFP+ (other end)
Transmission type: passive twinax copper direct attach cable
Supported protocols: 40GBase-CR4, 4×10GBase-CR, Ethernet, FCoE, InfiniBand
Conductor gauge: 30 AWG
MSA-compliant QSFP and SFP+ pin mapping
Typical use case: short-reach, within-rack and adjacent-rack links
How to use
Install the cable by inserting the QSFP connector into a compatible QSFP port and the four SFP+ connectors into the corresponding SFP+ ports of the target devices. Ensure both ends are fully seated and that the connected devices support passive QSFP-to-4×SFP+ DAC operation and the intended protocol (for example 40GBase-CR4 or 4×10GBase-CR). No external power or transceiver modules are required for passive operation. Verify link status and speed via the connected devices’ management interfaces after connection.
Usage recommendations
Use this cable for short, fixed connections inside racks or between adjacent racks; avoid running it in long cable trays or across long distances where attenuation and signal integrity requirements exceed its design. Confirm hardware compatibility with the device vendor documentation before deployment and perform a link test after installation.
