BlueLAN FN-CABLE-QSFP28-50CM-BL Cable Direct Attach QSFP28 0,5m, 100G, Twinax pasivo

Data center technicians connecting high-density switches and servers rely on the BlueLAN FN-CABLE-QSFP28-50CM-BL for short-reach 100G links. This 0.5-meter passive QSFP28 direct attach cable delivers 100 Gbps throughput with minimal latency and power draw, making it ideal for top-of-rack and adjacent-rack interconnects.

Key specifications

• Length: 0.5 m (50 cm)
• Connectors: QSFP28 to QSFP28
• Data rate: 100 Gbps
• Cable type: Passive twinax copper
• Protocol support: Ethernet, InfiniBand
• Compliance: SFF-8665 (QSFP28 MSA)
• Compatibility: BlueLAN systems and QSFP28 MSA-compliant ports

Why choose it

Passive twinax cables consume less power than active optical cables and introduce near-zero latency. The 50 cm length reduces cable clutter in dense racks while maintaining signal integrity for 100G connections.

Ideal use cases

• Top-of-rack switch-to-server links
• Adjacent rack interconnects in data centers
• High-performance computing clusters
• Short-reach 100G Ethernet or InfiniBand fabric

Good to know

This DAC is hot-pluggable and designed for use with BlueLAN equipment and any QSFP28 port that follows the MSA standard. It is a cost-effective alternative to fiber optic transceivers for short distances.
