## Summary description

BlueOptics BL290701X1M26-BL is a 1 m InfiniBand/fibre optic cable with a QSFP-DD male connector on one end and two QSFP56 male connectors on the other. Designed for high-speed data interconnects and server or switch breakout applications, the black 0.35 kg cable provides compact, short-reach connectivity between QSFP-DD ports and dual QSFP56 ports.

## Long description

BlueOptics BL290701X1M26-BL is a 1 m InfiniBand/fibre optic direct attach cable with a QSFP-DD male connector on one end and two QSFP56 male connectors on the other. The black, compact cable is intended for short-reach high-speed links and breakout connections between a single QSFP-DD port and two QSFP56 ports. It provides a simple physical connection for server, switch and storage hardware that requires up to 400 Gbit/s aggregated throughput over a one-meter reach.
Advantages
The cable supports high aggregated bandwidth and is designed for short-distance rack and adjacent-rack interconnects where low latency and compact cabling are required. As a passive direct attach type, it delivers low power consumption and a straightforward installation without active transceivers. The single-meter length reduces excess slack in dense rack environments and its standardized QSFP-DD and QSFP56 interfaces ensure compatibility with equipment that follows common multisource agreements.
Suitable for
Breakout connections from QSFP-DD ports to two QSFP56 ports
Short-reach links inside racks or between adjacent racks
High-performance Ethernet, InfiniBand and storage interconnects up to aggregated 400 Gbit/s
Server, switch and storage hardware that supports QSFP-DD/QSFP56 direct attach cabling
Key specifications
Cable length: 1 m
Connector type (end A): QSFP-DD male
Connector type (end B): 2 × QSFP56 male
Supported aggregated data rate: up to 400 Gbit/s (protocol-dependent)
Cable type: passive direct attach twinax (short-reach electrical link)
Weight: approx. 0.35 kg
Colour: black
How to use
Install the cable by inserting the QSFP-DD end into the source device port and the two QSFP56 ends into the corresponding destination ports, ensuring correct orientation and secure latching. Verify that the connected hardware supports passive DAC twinax cabling and the intended transport protocol (for example, 400GBase-CR8 or 2×200GBASE-CR4) in its firmware or compatibility list. After physical connection, check link status indicators and configure the host devices as required by the network or storage setup.
Usage recommendations
Use this 1 m BlueOptics QSFP-DD to 2×QSFP56 cable for short, high-bandwidth interconnects in dense rack deployments. Confirm device compatibility with QSFP-DD/QSFP56 passive DACs and select the one-meter length when minimal cable slack and reduced latency are priorities.
