## Summary description

The BlueOptics 49Y7890-BL is a 1 m InfiniBand/fibre optic cable featuring QSFP connectors on both ends. It is designed for high-speed data transmission and reliable connectivity in data centers and networking environments.

## Long description

The BlueOptics 49Y7890-BL is a 1 m InfiniBand/fibre optic cable with QSFP connectors on both ends. Designed for short-reach, high-speed links, this cable supports up to 40 Gbps data transmission and is intended for use in rack-mounted networking hardware, switches, routers and storage systems that accept QSFP-to-QSFP direct attach connections. The cable uses a twinax/direct attach form factor suitable for electrical signal transfer over short distances and follows MSA-compliant QSFP specifications to ensure interoperability with major hardware platforms.
Advantages
The cable provides a compact, low-latency connection for 40G applications and is suited for short-distance links inside or between adjacent racks. Its QSFP male-to-male connectors and 1 m length make it practical for dense rack installations where fixed, reliable direct connections are required. Manufactured to MSA guidelines and produced with quality components, the cable is intended to offer stable performance and compatibility with equipment that supports the corresponding QSFP DAC interface.
Suitable for
40G Ethernet links within or between adjacent server racks
InfiniBand and Fibre Channel short-reach connections where QSFP DAC is supported
High-density switch-to-switch or switch-to-server direct connections
Storage system interconnects and network aggregation points
Key specifications
Connector type: QSFP male to QSFP male
Length: 1 meter
Supported data rate: up to 40 Gbps
Cable type: direct attach / twinax (passive for short-distance electrical transmission)
Form factor: QSFP DAC, MSA-compliant
How to use
Install the BlueOptics 49Y7890-BL by inserting each QSFP connector into the matching QSFP port on the two devices to be linked. Ensure that both devices support passive QSFP direct attach cables and the intended 40G protocol (Ethernet, FCoE, Fibre Channel or InfiniBand). Route the 1 m cable within the rack or between adjacent racks to avoid tight bends and mechanical strain on the connectors. Do not force the connector — align and seat it until it clicks or locks according to the hardware vendor's port guidance.
Usage recommendations
For reliable operation, verify hardware compatibility with QSFP passive DACs before deployment, avoid sharp bends and excessive pulling on the cable, and maintain port cleanliness. Use the 1 m length for short intra-rack or adjacent-rack connections where passive twinax direct attach solutions are supported by your networking equipment.
