## Long description

The BlueOptics DAC Cable SFP-25G-CU1M-BL is a 1 m passive Direct Attach Copper (DAC) twinax cable with SFP28 connectors on both ends, supporting 25G Ethernet (25GBase-CR). Designed for short-reach, high-speed interconnects, this black SFP28-to-SFP28 cable is intended for use in data centers and rack environments to connect switches, routers, servers and storage hardware that support passive DAC connections.
Advantages
This DAC cable provides low-latency, energy-efficient 25G connectivity over a one-metre distance and requires no external transceivers or active components. Its passive twinax construction typically yields low power consumption and a simple, reliable electrical interface. The SFP28 connector form factor ensures compatibility with SFP28 ports that accept passive DAC cables, and the black jacket offers a discreet, professional appearance in rack installations.
Suitable for
Short-reach connections inside racks and between adjacent racks
High-density switch-to-switch or switch-to-server links at 25G
Top-of-rack and leaf-spine network architectures with SFP28 ports
Environments requiring low latency and low power interconnects
Key specifications
Cable type: Passive Direct Attach Copper (DAC), twinax
Nominal data rate: 25 Gbps per link (25GBase-CR)
Connectors: SFP28 to SFP28
Length: 1 m
Colour: Black
How to use
Ensure both network devices have SFP28 ports that support passive DAC cables. With devices powered down or following hot-plug guidance from your equipment vendor, insert each SFP28 connector fully into the corresponding port until the retention latch engages. After installation, verify link status and speed in the device management interface and confirm the equipment recognizes a 25G connection. If the link does not come up, consult the host hardware compatibility list and check that the ports are configured for the intended speed.
Usage recommendations
Use this 1 m DAC cable for intra-rack or adjacent-rack interconnects where short, cost-effective 25G links are required. Confirm host compatibility with passive SFP28 DACs and avoid excessive bending or strain at the connector ends to maintain signal integrity and cable lifetime.
