## Summary description

Passive Direct Attach Breakout cable BlueOptics A1DN-BL converts one QSFP 40GBASE-CR4 interface to four 10GBASE-CR SFP+ links. The 5 m, AWG26 copper assembly is intended for short-reach server, switch and aggregation connections in data centers or network racks. It supports passive electrical connectivity without transceivers and is suitable for 40 Gbps to 4×10 Gbps breakout applications.

## Long description

The BlueOptics A1DN-BL Direct Attach Breakout Cable is a passive QSFP-to-4×SFP+ copper assembly designed to convert a single 40GBASE-CR4 QSFP port into four independent 10GBASE-CR SFP+ links. With a 5 m length and AWG26 conductors, this cable provides short-reach electrical connectivity for server-to-switch, switch-to-switch or top-of-rack aggregation connections in data centers and network racks. The breakout construction eliminates the need for additional transceivers, enabling direct electrical breakout of 40 Gbps lanes into four 10 Gbps channels.
Advantages
This passive breakout cable offers a compact and cost-effective solution for high-density environments where rack-level or adjacent-rack connections are required. By converting one QSFP 40G link into four SFP+ 10G links it simplifies cabling topologies and reduces component count. The AWG26 copper wires deliver adequate signal integrity for short distances while the passive design minimizes power consumption compared with active or optical alternatives. The 5 m length balances flexibility and containment of signal attenuation for typical data center spans.
Suitable for
Short-reach server to top-of-rack switch connections
Switch uplinks and aggregation within the same or adjacent racks
High-density port breakout in network closets and data center patching
Direct electrical breakout where fiber transceivers are not required
Key specifications
Connector conversion: QSFP to 4 × SFP+
Standards supported: 40GBASE-CR4 to 4 × 10GBASE-CR
Cable type: passive copper breakout
Wire gauge: AWG26
Length: 5 meters
Data rate: 40 Gbps aggregated, 4 × 10 Gbps channels
Typical application: short-reach rack-level electrical connections
How to use
Plug the QSFP end into the 40GBASE-CR4 port of the switch or device and insert each SFP+ plug into the corresponding 10GBASE-CR SFP+ ports on the connected devices. Ensure ports are powered down or follow hot-swap guidance from equipment vendors if live insertion is required. Verify link negotiation and port configuration on both ends to confirm each 10 Gbps lane is recognized as a separate interface. Route the cable to avoid tight bends and secure within the rack to prevent strain on connectors.
Usage recommendations
Use this passive breakout cable for short-distance electrical connections inside racks or between adjacent racks; avoid runs beyond the specified length to prevent signal degradation. Confirm compatibility of the switches and servers with passive QSFP-to-SFP+ breakouts and check port settings for correct lane mapping and speed configuration.
