BlueLAN 834973-B22 Kompatibilný QSFP28 Direct Attach kábel - 1m, 100G, pasívny Twinax, 30 AWG 834973-B22-BL

Data center engineers connecting top-of-rack switches to high-performance servers rely on this BlueLAN 834973-B22 compatible QSFP28 direct attach cable. It provides a stable 100Gbps link over a 1-meter copper twinax assembly, eliminating the need for separate optical transceivers and reducing both cost and latency in dense rack environments.

Key specifications

• Connector type: QSFP28 to QSFP28
• Data rate: 100 Gbps
• Cable length: 1 meter
• Cable type: Passive copper twinax
• Wire gauge: 30 AWG
• Impedance: 100 Ohm
• Operating temperature: 0°C to 70°C
• Storage temperature: -40°C to 85°C
• Power consumption: < 0.1W
• Protocol support: IEEE 802.3bj (100GBASE-CR4), InfiniBand EDR/FDR

Why choose it

Passive DAC cables draw negligible power and introduce near-zero latency, making them ideal for short-reach 100G connections. The 30 AWG twinax construction balances flexibility with signal integrity, while the PVC jacket provides durability in high-density cabling.

Ideal use cases

• Top-of-rack switch to server connections
• High-performance computing clusters
• Enterprise data center interconnects

Good to know

This cable is hot-swappable and compatible with equipment using the BlueLAN 834973-B22 specification. It is RoHS compliant and supports both 100GBASE-CR4 Ethernet and InfiniBand EDR/FDR protocols.
