BlueLAN Compatible Mellanox MCP7H50-V003R26 Passive 200G QSFP56 to 2x100G QSFP56 Direct Attach Breakout Cable, 3m, AWG26 MCP7H50-V003R26-BL

Aggregate 200 Gbps throughput over a passive copper breakout cable that splits a single QSFP56 port into two 100 Gbps QSFP56 links. Built for Mellanox MCP7H50-V003R26 environments, this 3-meter AWG26 cable delivers dense, low-latency connectivity without active components.

Overview

The BlueLAN MCP7H50-V003R26-BL is a passive Direct Attach Breakout Cable (DAC) that connects a 200GBASE-CR4 QSFP56 port to two 100GBASE-CR2 QSFP56 ports. It is engineered for short-reach, high-bandwidth interconnects in data centers, high-performance computing clusters, and enterprise network fabrics. The cable uses 26 AWG copper conductors and is fully hot-pluggable.

What stands out

• Aggregate data rate of 200 Gbps across one QSFP56 to two QSFP56 breakout
• Passive copper design: no power draw, no signal regeneration, minimal latency
• 3-meter length with AWG26 conductors for rack-level and adjacent-rack cabling
• Compatible with Mellanox MCP7H50-V003R26 and equivalent QSFP56 ports
• Hot-pluggable for fast deployment and maintenance
