## Summary description

The BlueLAN QTAPCABLE28-2M is a passive direct attach breakout cable designed for high-speed data transfer. It features a QSFP28 connector on one end and four SFP28 connectors on the other, supporting 100GBASE-CR4 and 25GBASE-CR standards. With a length of 2 meters and AWG26 gauge, it ensures reliable performance and flexibility for data center applications. Its blue color provides easy identification in cable management systems.

## Long description

The BlueLAN QTAPCABLE28-2M is a passive direct attach breakout cable engineered for high-speed data center interconnects. One end terminates in a QSFP28 connector while the other end splits into four SFP28 connectors, enabling aggregation and breakout between 100G and 4×25G links. With a 2 meter length and AWG26 conductors, this blue cable provides predictable electrical performance for short-reach copper links and simple color-coded cable management.
Advantages
This passive QSFP28 to 4×SFP28 breakout cable supports 100GBASE-CR4 and 25GBASE-CR signaling, offering a cost-effective way to connect high-density switches, routers, and server NICs without external transceivers. The AWG26 gauge and direct-attach construction minimize latency and power requirements compared with active cables. The blue jacket improves visual identification in racks and cabling bundles, and the 2 m length balances reach and manageability in typical data center topologies.
Suitable for
Connecting a 100G QSFP28 port to four 25G SFP28 ports in aggregation or breakout scenarios
Short-reach copper links between switches, patch panels, and servers within a rack or between adjacent racks
High-density data center environments requiring low-latency, low-power direct attach solutions
Key specifications
Connector type: QSFP28 to 4×SFP28
Supported standards: 100GBASE-CR4, 25GBASE-CR
Length: 2 meters
Conductor gauge: AWG26
Cable color: blue
Passive direct attach (no active electronics)
How to use
Insert the QSFP28 end into the 100G port and the four SFP28 ends into their corresponding 25G ports, ensuring each connector is fully seated and the latch engages. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius recommended for AWG26 copper assemblies. The passive breakout is plug-and-play with compatible devices and does not require configuration beyond verifying link status and interface settings on connected equipment.
Usage recommendations
Use this cable for short-distance interconnects inside racks or between adjacent racks. Verify that connected ports support 100GBASE-CR4 or 25GBASE-CR operation and that device firmware/driver versions are current. Avoid running the cable near strong electromagnetic interference sources and replace the cable if the jacket or connectors show visible damage.
