## Summary description

The BlueLAN 25GB-4-C02-QSFP28M is a passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 direct attach breakout cable. With a length of 2 meters and AWG26, it offers reliable high-speed data transmission for data centers and networking applications. Its durable design ensures longevity and performance, making it an ideal choice for connecting high-bandwidth devices.

## Long description

The BlueLAN 25GB-4-C02-QSFP28M is a passive direct-attach breakout cable that converts a single QSFP28 100GBASE-CR4 interface into four independent 25GBASE-CR SFP28 channels. With a 2 meter length and AWG26 conductors, this QSFP28 to 4x25GBASE-CR SFP28 cable provides a compact, low-latency copper connection for short-reach interconnects in racks and server cabinets. The cable is intended for reliable high-speed data transmission in data centres, aggregation switches and high-density network environments.
Advantages
The cable supports four 25G channels from a single QSFP28 port, enabling efficient port breakout without active transceivers. Its AWG26 construction offers predictable signal integrity for multi-lane copper links, and the passive design eliminates the need for external power. The 2 m length balances reach and manageability inside racks while the rugged jacket and connector housings ensure mechanical durability and stable electrical contact.
Suitable for
 Server to top-of-rack or leaf switch connections within the same rack or adjacent racks
 High-density aggregation and spine switch interconnects where port breakout is required
 Short-reach switch-to-switch or switch-to-router links in data centres and colocation facilities
 Environments where low-latency, low-power passive copper links are preferred over optical transceivers
Key specifications
 Interface: QSFP28 (one end) to 4 × SFP28 (other end), passive breakout cable
 Supported protocol: 100GBASE-CR4 to 4 × 25GBASE-CR
 Length: 2 meters
 Conductor size: AWG26
 Cable type: Copper direct-attach cable (DAC), passive
 Typical use: Short-reach rack- and cabinet-level interconnects
How to use
Insert the QSFP28 end into the 100G port on the source device and connect the four SFP28 ends to four corresponding 25G ports on the destination device or to four SFP28-capable modules. Ensure each connector seats fully and the retention latches engage. Confirm link status on both devices and configure port breakout or lane mapping if required by the switch or host firmware. For proper operation, verify that the devices support passive QSFP28-to-4×SFP28 direct attach breakout cables and that the port speeds are set to 25G lanes where applicable.
Usage recommendations
Route the cable with gentle bends and avoid sharp kinks; maintain the manufacturer’s minimum bend radius. Keep the cable clear of high-power heat sources and electromagnetic interference. For best performance, use this passive breakout cable for short-reach connections within racks or between adjacent racks and follow your equipment vendor’s compatibility guidance before deployment.
