Ideal for short-distance connections, it offers reliable performance and low latency, making it suitable for data centers and enterprise networks.

## Long description

The BlueOptics DAC-SFP-25G-50CM-BL is a 0.5 m Direct Attach Copper (DAC) cable with SFP28 male connectors on both ends, designed for short-distance, high-speed links in rack and adjacent-rack installations. The cable supports electrical 25GBase-CR connections and is intended for use with networking equipment that accepts SFP28 interfaces. With a compact 0.5 m length and twinax copper construction, this DAC cable provides a straightforward physical link for switches, routers and storage hardware in data center and enterprise environments.
Advantages
The BlueOptics DAC-SFP-25G-50CM-BL offers low latency and low power consumption typical of passive twinax DACs, making it suitable for high-throughput short-reach connections. Manufactured to MSA-compliant form factors and using quality components, the cable provides reliable electrical transmission for 25 Gbit/s applications and a stable mechanical fit in SFP28 ports. Its short length helps minimize signal degradation and simplifies cable management inside racks.
Suitable for
 Short-distance interconnects between rack-mounted switches and adjacent racks
 Direct connections between SFP28 ports on switches, routers and servers
 High-performance 25GBase-CR Ethernet and related storage or converged network links
Key specifications
 Length: 0.5 m
 Connector type: SFP28 male to SFP28 male
 Data rate: up to 25 Gbit/s
 Cable type: passive twinax copper (30 AWG)
 Typical application: 25GBase-CR electrical links
 Product colour: Black, Silver
 Weight: 0.08 kg
How to use
Install the DAC by inserting each SFP28 male connector into the corresponding SFP28 port on the devices to be linked. Ensure both devices support passive DAC twinax copper connections and the 25GBase-CR electrical protocol. Secure the cable routing inside the rack to avoid stress on the connectors and prevent sharp bends. No external power or configuration on the cable itself is required; link negotiation and protocol settings are handled by the connected hardware.
Usage recommendations
Use this 0.5 m DAC for direct, short-reach connections within racks or between adjacent racks where a low-latency, low-power, cost-effective 25G electrical link is required. Verify device compatibility with passive SFP28 DACs before deployment and avoid excessive bending radii or mechanical strain to preserve connector integrity and long-term reliability.
