## Summary description

Passive BlueOptics breakout direct-attach cable QDD-4X100G-1M connects a single QSFP-DD 400GBASE-CR8 port to four QSFP56 100GBASE-CR ports. Length 1 meter, conductor gauge AWG26, designed for short-reach copper interconnects in data centers and network racks. Suitable for aggregation, switch-to-switch links and cross-connects where 400G-to-4×100G splitting is required.

## Long description

BlueOptics passive QSFP-DD to 4×QSFP56 breakout cable QDD-4X100G-1M is a 1 metre copper direct-attach cable designed to split a single 400G QSFP-DD interface into four independent 100G QSFP56 channels. The cable implements 400GBASE-CR8 to 4×100GBASE-CR electrical signalling and uses AWG26 conductors for short-reach, high-density interconnects in racks and patch panels. It is a passive, fixed-length breakout solution intended for use in data centres and enterprise network environments where cost-effective, low-latency copper connections are required for aggregation and cross-connect applications.
Advantages
This passive breakout cable offers a compact and simple method to convert a single 400G QSFP-DD port into four 100G QSFP56 links without the need for additional transceivers or active electronics. The AWG26 conductor gauge provides a balance between flexibility and signal integrity for short distances. Its 1 m length and direct-attach design reduce connector count and insertion complexity, enabling straightforward installation in dense switch and server topologies while keeping power consumption minimal due to the lack of active components.
Suitable for
Aggregating multiple 100G links from a single 400G port in top-of-rack and leaf-spine architectures
Switch-to-switch connections and cross-connects within the same rack or adjacent racks
Short-reach copper interconnects where fibre transceivers are not required
High-density patching scenarios in data centre environments
Key specifications
Connector breakout: QSFP-DD (single end) to 4×QSFP56 (other end)
Data rate: 400G to 4×100G
Cable type: Passive copper direct-attach (breakout)
Transmission standard: 400GBASE-CR8 to 4×100GBASE-CR
Length: 1 m
Conductor gauge: AWG26
Compatibility: Designed for QSFP-DD and QSFP56 ports supporting passive DAC connections
How to use
Install the breakout cable by plugging the QSFP-DD end into the 400G port and the four QSFP56 ends into the corresponding 100G ports on the destination devices. Ensure both ends are fully seated and that port indicators or management software report link status. No external power or configuration is required for the passive cable itself, but verify that the connected switches or servers support passive DAC connections and the necessary lane mapping or breakout mode. Route the cable to avoid sharp bends and maintain recommended bend radius for AWG26 cables.
Usage recommendations
Use this cable for short-reach connections within racks or between adjacent racks up to 1 m. Confirm compatibility with your networking equipment vendor regarding passive DAC support and QSFP-DD to QSFP56 breakout mapping. Avoid running the cable near high-interference sources and maintain proper airflow in racks to prevent thermal stress on connectors.
