## Summary description

Direct-attach copper (DAC) QSFP28 cable BlueOptics SFP-DAC100-2M-BL provides a 2 m 100GBASE-CR4 connection between QSFP28 ports. Designed for short-reach interconnects in data centers and high-speed networking equipment, it supports 100 Gbit/s links and offers a fixed QSFP28-to-QSFP28 connection in a black jacket.

## Long description

BlueOptics SFP-DAC100-2M-BL is a passive QSFP28 Direct Attach Cable (DAC) designed for short-range 100G electrical connections in racks and between adjacent racks. The 2 m twinax copper cable provides a QSFP28-to-QSFP28 connection for use with network switches, routers and storage systems that support passive 100G DAC links. The cable is black, lightweight and intended for data-center and high-density rack environments where short, high-bandwidth links are required.
Advantages
The passive DAC design requires no active components in the cable itself, resulting in very low power consumption and low latency. Manufactured to common MSA standards with components from established suppliers, the cable offers predictable interoperability and a long service life. Its simple construction yields a low failure rate and cost-effective deployment for short-range 100G links.
Suitable for
Short-distance interconnects inside racks
Connections between adjacent racks in data centres
High-density switch-to-switch 100G links
Switch-to-storage or server 100G links that accept passive QSFP28 DACs
When it may not be suitable
This passive QSFP28 DAC is intended for short-range electrical transmission and is not suitable for long-distance links or fibre runs. It requires networking equipment that explicitly supports passive 100G DAC (QSFP28) modules; it will not function if the host hardware mandates active or optical transceivers.
Key specifications
Cable type: Direct Attach Copper (DAC), twinax
Connector A: QSFP28 male
Connector B: QSFP28 male
Maximum data rate: 100 Gbit/s
Length: 2 m

How to use
Install the QSFP28 connectors into compatible QSFP28 ports on the two devices you wish to connect, ensuring the ports support passive 100G DAC cables. Align the connector latch, insert until it seats firmly and secure any cage latches if present. No additional configuration is required at the cable level; configuration and link activation are handled by the connected devices and their firmware.
What to consider before purchase
Verify that both devices support passive QSFP28 100G DAC connections
Confirm that a 2 m length is appropriate for your rack layout
Ensure QSFP28-to-QSFP28 compatibility with your switch or server ports
Usage recommendations
Use in clean, secure rack environments and avoid tight bends or strain on the twinax cable. Check device compatibility lists and, if possible, test a sample in your environment to confirm full interoperability.
