The passive copper assembly offers low-latency, high-throughput connectivity for short-reach links in data centers and network racks.

## Long description

BlueOptics DAC cable QSFP28 QSFP-100G-D-CAB-1M-BL is a 1 m direct attach copper (DAC) cable engineered for 100G networking. The cable provides a direct QSFP28-to-QSFP28 link for compatible switches, routers and servers, enabling short-reach, high-throughput connections inside data centre racks and network equipment clusters. As a passive copper assembly, it delivers low-latency performance and reliable electrical signalling for 100 Gigabit Ethernet interconnects over a one-metre distance.
Advantages
This DAC cable offers a compact, cost-efficient alternative to optical transceivers for short-distance 100G links. The one-metre length reduces excess cabling in dense rack environments while preserving signal integrity for high-bandwidth traffic. Passive construction eliminates the need for external power, simplifies installation and provides stable latency characteristics appropriate for switch-to-switch, server-to-switch and switch-to-router connections.
Suitable for
 Short-reach 100 Gigabit Ethernet links within data centre racks
 Interconnecting QSFP28 ports on switches, routers and servers
 High-throughput, low-latency connections for aggregation and spine-leaf topologies
 Environments where cost-effective, low-power connections are required
Key specifications
 Connector type: QSFP28 to QSFP28 direct attach
 Link rate: 100 Gigabit Ethernet
 Cable type: Direct attach copper (passive)
 Length: 1 metre
 Form factor: QSFP28 compatible assembly for data centre equipment
 Typical use case: Short-reach, intra-rack and adjacent-rack connections
How to use
Install the DAC cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch engages. Ensure both ends are fully seated and that connected equipment is compatible with passive QSFP28 DACs and supports 100G links. For best results, connect devices that are powered off or follow hot-plug procedures recommended by the equipment manufacturer. Route the cable to avoid sharp bends and mechanical strain and verify link status using device LEDs or management interfaces.
Usage recommendations
Use this 1 m passive DAC cable for short-distance interconnects where optical modules are unnecessary. Keep the cable within recommended bend radius, avoid exposure to excessive heat or moisture, and confirm device compatibility with QSFP28 passive DACs to ensure stable 100G operation.
