Model: X-100G-QSFP28-4xSFP28

Overview

100G QSFP28 to 4x SFP28 Direct Attach Cable (DAC) series provides a high-density, cost-efficient solution for optimizing network flexibility in data centers and enterprise environments. This breakout cable splits a single 100G QSFP28 port into four independent 25G SFP28 channels, enabling seamless connectivity between high-speed switches and multiple 25G devices, such as servers, storage systems, or access switches. Supporting an aggregate bandwidth of 100Gbps (4x25Gbps), it ensures ultra-low latency and reliable data transmission over distances up to 3 meters.

Constructed with premium shielded copper, the passive DAC series eliminates the need for additional transceivers, reducing power consumption and complexity. Its plug-and-play design simplifies deployment, while robust shielding minimizes electromagnetic interference (EMI) in high-density setups. Backward compatible with 10G/25G SFP28 interfaces, this series offers future-proof scalability for evolving network architectures.

Ideal for cloud computing, AI clusters, and distributed storage, the 100G QSFP28 to 4x SFP28 DAC series maximizes port utilization, lowers infrastructure costs, and delivers a power-efficient alternative to optical modules for short-reach, high-speed applications.
