100G QSFP28 passive DAC cable for short-distance data center interconnects.
When connecting switches and servers within the same rack, optical modules often add unnecessary cost and power overhead. This QSFP28 passive copper cable assembly provides a direct, energy-efficient alternative for short-reach 100G links.
Supporting up to 100Gb/s bi-directional data rates with less than 0.1W power consumption, this 3-meter 28AWG cable eliminates active component latency while ensuring signal integrity via shielded differential pairs. Its compliance with IEEE 802.3bj guarantees interoperability in demanding environments.
Ideal for intra-rack connections in AI clusters and cloud data centers, the LRDAC-QSFP28-3M delivers high reliability at a fraction of optical transceiver costs. It enables dense, low-latency networking without compromising on performance or thermal management.
Supports up to 100Gb/s bi-directional data links compliant with QSFP28 MSA.
Passive design consumes less than 0.1W, reducing data center cooling costs.
All-metal housing provides superior EMI performance for reliable signal integrity.
Fully compliant with IEEE 802.3bj, 802.3by and Infiniband EDR specifications.
