It provides an efficient, low-latency connectivity solution for high-performance computing and data center environments.

## Long description

The BlueOptics 400G OSFP to OSFP passive twinaxial copper Direct Attach Cable (DAC) is a high-performance connectivity solution designed for rapid data transmission over short distances. With a length of 0.5 meters, this cable provides a reliable, low-latency link between networking hardware such as switches, routers, and storage systems within data centers or server racks.
Advantages
This passive DAC offers exceptional efficiency by requiring minimal power, making it an environmentally friendly and cost-effective choice for high-speed network environments. Its robust construction ensures high signal integrity and durability, significantly reducing the risk of link failures. By utilizing high-quality components, the cable is engineered for long-term reliability, supporting demanding applications that require consistent 400G throughput without the complexity of active optical components.
Suitable for
High-performance computing clusters
Data center rack-to-rack connectivity
Switch-to-server high-speed links
Storage area network (SAN) infrastructure
When it may not be suitable
This cable is a passive copper solution and is not intended for long-distance connections, as it is limited to a 0.5-meter reach. It is also not suitable for environments where active signal amplification is required or where the connected hardware does not explicitly support the 400G OSFP passive copper standard.
Key specifications
Cable length: 0.5 m
Connector type: OSFP to OSFP
Data rate: 400 Gbit/s
Cable type: Passive twinaxial copper
Weight: 0.15 kg
Colour: Orange
How to use
To install the cable, simply insert the OSFP connectors into the corresponding ports on your networking equipment until they click securely into place. Ensure that both devices are powered on and configured to support the 400G connection. No additional software configuration is typically required, as the cable functions as a direct physical link between the ports.
What to consider before purchase
Verify that your hardware ports support OSFP connectors
Ensure the 0.5-meter length is sufficient for your rack layout
Confirm that your equipment supports passive 400G copper DAC technology
Usage recommendations: For optimal performance and to maintain signal integrity, avoid bending the cable beyond its minimum bend radius during installation. Ensure that the connectors are kept clean and free of dust before insertion into your networking hardware.
