## Summary description

The BlueLAN LSWM1QSTK3 is a passive 40GBASE-CR4 QSFP to 4x10GBASE-CR SFP+ direct attach breakout cable. With a length of 1 meter and AWG30, it ensures high-speed data transmission and reliable connectivity. Ideal for data centers and high-performance computing environments, this cable provides excellent performance with minimal signal loss, making it a perfect choice for network expansion and upgrades.

## Long description

The BlueLAN LSWM1QSTK3 is a passive QSFP to 4xSFP+ direct attach breakout cable designed for short-reach 40GBASE-CR4 interconnects. At 1 meter length and constructed with AWG30 twinax, this blue network cable provides a compact, low-latency physical link for connecting a 40G QSFP port to four 10G SFP+ ports. The cable is intended for use in dense networking environments where reliable, low-loss copper connections are required for server, switch and storage aggregation.
Advantages
The passive construction reduces power draw and complexity by avoiding active electronic components while maintaining the signal integrity needed for 40GBASE-CR4 and 10GBASE-CR links. A 1 m length minimizes insertion loss and latency for short-reach applications. AWG30 conductors and quality shielding provide consistent performance across the four SFP+ breakout channels. The single-unit QSFP to 4xSFP+ design simplifies cabling in racks and saves space compared with separate transceivers and patch cables.
Suitable for
 Data center top-of-rack and spine aggregation
 Direct server-to-switch connections in high-density racks
 High-performance computing clusters requiring 40G to 4×10G breakout
 Network upgrades and expansion where short copper links are preferred
Key specifications
 Connector type: QSFP to 4 × SFP+
 Data rate: 40 Gbit/s aggregated (4 × 10 Gbit/s lanes)
 Cable type: Passive twinax copper
 Conductor size: AWG30
 Length: 1 meter
 Color: Blue
How to use
Insert the QSFP end into the 40G QSFP port and insert each SFP+ end into the corresponding 10G SFP+ ports. Ensure both devices are powered off or follow hot-plug guidelines from the equipment manufacturer when connecting or disconnecting. Verify link status and interface settings on the connected network equipment after installation. Use cable management to avoid excessive bending or strain on the connectors; maintain the recommended minimum bend radius for twinax cables.
Usage recommendations
For optimal performance, use this 1 m passive breakout cable in short-reach aggregated links within the same rack or neighboring racks. Avoid routing through sharp bends, cable crush zones, or high-interference environments. Confirm compatibility with the switch or server vendor's supported direct-attach cables if vendor-specific interoperability lists are required.
