BlueOptics QTAPCABLE28-2M Compatible BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 2m, AWG26

The BlueOptics QTAPCABLE28-2M compatible BlueLAN passive direct attach breakout cable is designed for high-performance data center and enterprise network environments. It provides a cost-effective, low-power solution for 100 Gigabit Ethernet connectivity by breaking out a single QSFP28 port into four independent 25 Gigabit SFP28 links. This cable is fully compliant with the 100GBASE-CR4 and 25GBASE-CR standards and is an ideal replacement for the Chelsio QTAPCABLE28-2M.

Advantages

This passive twinax cable offers ultra-low latency and power consumption under 0.5W, making it an energy-efficient choice for high-density deployments. The breakout design allows for flexible network architecture, enabling connection of a 100G switch port to four 25G servers or switches. The 2-meter length with AWG26 gauge provides reliable signal integrity for short-reach interconnects.

Suitable for

• Data center top-of-rack and end-of-row cabling
