## Summary description

The BlueOptics QSFP28-DAC-1M-RW is a 1 meter long passive DAC cable with QSFP28 connectors on both ends. It is designed for high-speed data transmission in data centers and networking applications, providing a reliable and efficient connection for servers and switches.

## Long description

The BlueOptics QSFP28-DAC-1M-RW is a 1 metre passive direct-attach copper (DAC) cable with QSFP28 male connectors on both ends, designed for short-reach, high-speed interconnections in data centres and enterprise networks. It provides a reliable, low-latency link for QSFP28 ports supporting 100 Gigabit Ethernet and other high-bandwidth applications. The cable's compact design and fixed length simplify installation between switches, routers, servers and NICs in rack-mounted environments.
Advantages
This QSFP28 DAC cable offers low power usage compared with active optical alternatives, minimal signal latency and deterministic performance typical of copper DACs. Its one-metre length reduces cable clutter while maintaining signal integrity over short distances. The robust QSFP28 connectors ensure secure mechanical mating and compatibility with standard QSFP28 ports, while the passive design eliminates the need for external transceivers or power.
Suitable for
Short-reach server-to-switch 100GbE connections in racks
Inter-switch links in data centre top-of-rack and leaf-spine architectures
Direct connections between QSFP28-capable network interface cards and switches
Test lab setups and temporary deployments requiring reliable high-bandwidth links
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 1 metre (fixed)
Type: Passive direct-attach copper (DAC)
Supported data rate: up to 100 Gbit/s per cable when used with compatible QSFP28 ports
Cable colour: blue
Form factor: compact, low-profile cable assembly for high-density racks
How to use
Install the BlueOptics QSFP28-DAC-1M-RW by inserting each QSFP28 male connector into the corresponding QSFP28 port on your devices until the latch engages. Ensure both devices support passive DAC connections and matching speed settings. No additional drivers or power supplies are required; the cable functions as a direct electrical connection. For initial configuration, verify link status and negotiated speed on connected devices and adjust port settings if necessary.
Usage recommendations
For optimal performance, use this 1m passive DAC for short-distance connections within the same rack or adjacent racks. Avoid sharp bends and excessive pulling force when routing the cable. Confirm compatibility with your switch or NIC vendor's QSFP28 port policies and, when deploying in high-density environments, maintain appropriate airflow and cable management to prevent interference with cooling.
