## Summary description

The BlueOptics QDD-2X200G-2M-BL is a 2-meter InfiniBand/fibre optic cable featuring a QSFP-DD connector on one end and two QSFP56 connectors on the other. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable performance and low latency. The cable is constructed with high-quality materials for durability and optimal signal integrity.

## Long description

The BlueOptics QDD-2X200G-2M-BL is a 2‑meter direct attach cable (DAC) featuring a QSFP-DD connector on one end and two QSFP56 connectors on the other. It supports 400GBase-CR8 and 2x200GBase-CR4 electrical transmission over twinax copper with 26 AWG conductors and is MSA-compliant. Designed for short-range high‑speed links in racks and between adjacent racks, this cable provides low latency and reliable signal integrity for InfiniBand, Ethernet and storage interconnects.
Advantages
The cable delivers up to 400 Gbit/s aggregate throughput using a QSFP-DD to 2xQSFP56 pinout while remaining passive, which reduces power consumption and latency compared with active solutions. Construction uses industry-standard twinax materials and compliant mechanical interfaces to ensure compatibility with hardware platforms that support the corresponding QDD/2xQSFP56 wiring. The 2 m length is suitable for typical rack-to-rack or intra-rack connections and the 26 AWG conductor provides a balance of flexibility and signal performance.
Suitable for
High-speed switch-to-switch connections within the same rack or adjacent racks
Server or storage system uplinks requiring 400G or 2x200G electrical links
InfiniBand fabrics and Ethernet backplane interconnects in data centers
Key specifications
Connector type: QSFP-DD (one end) to 2×QSFP56 (other end)
Length: 2 meters
Transmission: Passive twinax copper, 400GBase-CR8 / 2×200GBase-CR4
Conductor gauge: 26 AWG
Compliance: MSA-compliant mechanical and electrical pinout
Applications supported: Ethernet, InfiniBand, FCoE and Fibre Channel up to 400 Gbit/s over specified distance
How to use
Install the cable by inserting the QSFP-DD plug into a compatible QSFP-DD port and the two QSFP56 plugs into corresponding QSFP56 ports. Ensure both devices support passive DAC connections and the intended 400GBase-CR8 or 2×200GBase-CR4 transmission mode. Handle connectors by their housing, avoid excessive bending near the connector boot, and verify link status LEDs on connected equipment after insertion. No external power or configuration is required for the cable itself; configuration is performed on the connected hardware as needed for link negotiation and protocol settings.
Usage recommendations
Use this passive QSFP-DD to 2×QSFP56 twinax cable for short-range electrical interconnects where low latency and low power consumption are priorities. Confirm vendor compatibility with your network equipment and firmware, route the cable to avoid sharp bends and mechanical strain, and keep the operating environment within the equipment manufacturer’s temperature and humidity limits to maintain long service life.
