BlueLAN 980-9I48H-00C003 Compatible QSFP28 to 4x SFP28 Passive Copper Breakout DAC Cable, 3m, 100G to 4x25G 980-9I48H-00C003-BL

Aggregate 100 Gbps over a passive copper breakout cable: this BlueLAN 980-9I48H-00C003 compatible DAC splits a QSFP28 port into four SFP28 links, each running at 25 Gbps, over a 3-meter span.

Overview

The BlueLAN SC282701L3M26 is a direct attach copper (DAC) breakout cable engineered for NVIDIA networking equipment, including Mellanox switches and adapters. It connects a single QSFP28 port on one end to four independent SFP28 ports on the other, enabling high-density 25G server connectivity from a 100G uplink. The cable is passive, drawing no additional power, and is hot-pluggable for simple installation and replacement.

What stands out

• Aggregate data rate of 100 Gbps, with four lanes of 25 Gbps each
• QSFP28 to 4x SFP28 breakout configuration for flexible top-of-rack deployments
• Passive copper design for low latency and zero power consumption
• 3-meter length suits adjacent rack connections
• Compatible with NVIDIA Ethernet standards: 100GBASE-CR4 to 4x 25GBASE-CR
