Introduction

Mellanox direct attach copper (DAC) passive cable assemblies are high speed, cost-effective alternatives to fiber optics in InfiniBand EDR 100Gb/s applications.

Based on the QSFP28 electrical connector, 100G EDR DAC cables are configured as 4 channels of 25G NRZ. Each QSFP28 connector includes an EEPROM providing product information which can be read by the host system.

Mellanox’s unique quality, passive, copper cable solutions provide power-efficient connectivity for short distance interconnects. They enable higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers.

Rigorous cable production testing ensures best out-of-the-box installation experience, performance and durability.
