100G QSFP28 Passive DAC

The Wolon 100G QSFP28 Passive Direct Attach Copper (DAC) Cable is a cost-effective, high-density solution for short-reach 100 Gigabit Ethernet interconnects. This twinax copper cable features hot-pluggable QSFP28 connectors on both ends, delivering full 100 Gbps throughput without the need for optical transceivers or external power. Engineered for next-generation data centers, enterprise cores, and high-performance computing clusters, it offers ultra-low latency, superior signal integrity, and seamless interoperability with all major switch and router vendors.

100 Gbps High-Speed Transmission
Supports full 100 Gbps over four 25 Gbps lanes; backward compatible with 25 GbE QSFP28ports for flexible deployment.

Passive DAC Design
No active components or power draw-delivers plug-and-play simplicity and minimal powerconsumption(≤1 W).

QSFP28 MSA Compliant
Fully adheres to QSFP28 MSA, SFF-8436, and SFF-8655 specifications, ensuring broad compatibility with Cisco, Arista, Juniper, HPE, and more.

Low Insertion Loss & Minimal Crosstalk
High-quality AWG30 twinax conductors maintain signal integrity with insertion loss typically <2dB and crosstalk <-30 dB.

Compact & Flexible
30 AWG cable gauge and minimum bend radius of 25 mm support high-density rack cablingwithout performance degradation.

RoHS & Environmental Compliance
RoHS-certified construction and PVC jacket maintain reliability across 0 °C to 70 °C operatingtemperatures and -40 'C to 85 °C storage.
