## Summary description

Direct-attach passive breakout cable by BlueOptics converting a 400GBASE-CR8 QSFP-DD interface into four 100GBASE-CR QSFP56 links. 1 meter length, AWG26 construction suitable for short-reach copper connections between switches, routers or NICs supporting 400G QSFP-DD and 100G QSFP56 ports. Intended for data center aggregation, server uplinks and high-density switch interconnects where passive copper breakout simplifies cabling.

## Long description

Passive 400GBASE-CR8 to 4×100GBASE-CR QSFP-DD to 4×QSFP56 Direct Attach Breakout Cable BlueOptics 1 m AWG26 is a passive copper breakout cable designed to split a single 400G QSFP-DD connection into four independent 100G QSFP56 channels. With a 1 meter length and AWG26 conductor gauge, this cable provides a short-reach physical layer solution for connecting high-density switches, routers and network interface cards that support 400G QSFP-DD and 100G QSFP56 interfaces. The construction and pinout follow the established CR8 to CR breakout mapping to ensure compatibility with devices that accept passive copper breakout assemblies.
Advantages
This passive breakout cable offers a compact and low-latency interconnect option without active electronics, reducing power consumption and eliminating the need for external transceivers. The AWG26 copper conductors provide reliable signal integrity for short-reach links while the single-cable breakout simplifies rack cabling and saves port density. The standardized QSFP-DD to QSFP56 pinout enables straightforward integration into data center aggregation layers, server uplinks and high-density top-of-rack switch deployments.
Suitable for
 Data center aggregation and spine-leaf interconnects
 Server uplinks to top-of-rack or aggregation switches
 High-density switch-to-switch connections in short-reach scenarios
 Lab and test environments for validating QSFP-DD to QSFP56 breakout functionality
Key specifications
 Interface: QSFP-DD (400GBASE-CR8) to 4 × QSFP56 (100GBASE-CR)
 Cable type: Passive direct attach copper breakout
 Length: 1 meter
 Conductor gauge: AWG26
 Reach: short-reach copper connections (rack/row level)
 Color: Blue
How to use
Install the cable by inserting the QSFP-DD end into the 400G port and the four QSFP56 ends into the corresponding 100G ports on the target devices. Ensure that devices support passive breakout cabling and the required port modes (CR8 to 4×CR). Confirm link status and lane mapping in device management interfaces after insertion. There is no separate power or configuration required for the cable itself; any required settings are applied on the connected equipment.
Usage recommendations
Use this passive AWG26 breakout cable for short-distance connections within the same rack or adjacent racks. Verify compatibility with vendor documentation for QSFP-DD passive breakouts and check that devices support the intended lane splitting and speed negotiation before deployment. Avoid routing through tight bends or sharp edges and maintain appropriate strain relief at connectors to preserve signal integrity.
