## Summary description

Passive direct-attach breakout cable by BlueOptics (MPN BN-QS-SP-CBL-5M-BL) converts a single QSFP 40GBASE-CR4 link into four independent 10GBASE-CR SFP+ connections. The 5-meter AWG26 copper assembly provides a cost-effective solution for short-reach server-to-switch and switch-to-switch interconnects where QSFP ports must be split into multiple 10GbE ports. Compatible with NVIDIA BN-QS-SP-CBL-5M specification.

## Long description

BlueOptics passive QSFP-to-4xSFP+ Direct Attach Breakout Cable 5 m is a copper DAC assembly that converts a single 40GBASE-CR4 QSFP interface into four independent 10GBASE-CR SFP+ links. The 5 metre AWG26 construction is intended for short-reach, boardroom and data center top-of-rack interconnects where a 40GbE port needs to be split into multiple 10GbE connections. This passive breakout cable provides a plug-and-play electrical path without active components, reducing power consumption and simplifying deployment in compatible network equipment.
Advantages
The passive design offers low latency and no external power requirement, while the AWG26 copper conductors ensure reliable signal integrity over the specified 5 m distance. Using a single QSFP end that breaks out into four SFP+ connectors saves port resources and cabling complexity when consolidating uplinks or connecting multiple 10GbE servers to a 40GbE switch. The cable’s fixed assembly eliminates the need for transceivers and reduces total cost of ownership for short-distance links.
Suitable for
Splitting a 40GbE QSFP port into four 10GbE SFP+ ports in racks and server cabinets
Short-reach switch-to-switch or switch-to-server connections within the same rack or adjacent racks
Top-of-rack aggregation where consolidation of uplinks is required
Environments where passive, low-power cabling is preferred over optical transceivers
Key specifications
Connector types: 1×QSFP (40GBASE-CR4) to 4×SFP+ (10GBASE-CR)
Cable length: 5 m
Conductor gauge: AWG26
Signal type: Passive copper direct attach
Intended reach: short-reach data center and rack-level interconnects
Latency: electrical passive, minimal added latency
How to use
Insert the QSFP end into the 40GbE QSFP port on the source device and connect each SFP+ plug to the target 10GbE ports on switches or servers. Ensure both devices support passive QSFP-to-SFP+ breakout operation and that link speed/negotiation settings on the network equipment are configured for 10GbE per SFP+ lane. Route the cable to avoid tight bends and secure it to prevent strain on the connectors. No additional power or transceivers are required for operation.
Usage recommendations
Verify compatibility with the switch and server vendor documentation for passive breakout cables before installation. Use within the specified 5 m length and handle the assembly carefully to maintain connector integrity; avoid kinking the cable and keep it clear of high-interference power sources.
