## Summary description

The BlueOptics DAC-0.5M-EX-BL is a 0.5m long DAC cable featuring SFP+ connectors on both ends. It is designed for high-speed data transmission in data centers and networking applications. The male/male configuration ensures compatibility with various devices, providing reliable connectivity and reduced latency. Ideal for connecting servers, switches, and storage devices.

## Long description

The BlueOptics DAC-0.5M-EX-BL is a 0.5 m direct attach copper (DAC) cable with SFP+ male connectors on both ends designed for short‑reach, high‑speed links in racks and between adjacent racks. It implements a passive twinax copper design suitable for 10GBase‑CR applications and is compatible with equipment that supports standard SFP+ passive DAC connections. The cable is intended for low‑latency, low‑power connections between servers, switches and storage devices where short, reliable point‑to‑point links are required.
Advantages
This DAC cable provides a fixed 0.5 m copper link with SFP+ male/male connectivity, offering predictable electrical performance for 10 Gbps applications without additional transceivers. The passive twinax construction keeps power consumption and latency low while simplifying installation and reducing component count. Built to MSA‑compliant mechanical and electrical dimensions, the cable uses high‑quality materials and components to support long service life and stable signal integrity in short‑distance data center environments.
Suitable for
Short‑reach connections between rack‑mounted switches and servers
Direct server‑to‑storage or switch‑to‑switch links within the same rack or adjacent racks
10 Gbps Ethernet, FCoE and other protocols supported over SFP+ passive DAC twinax
Key specifications
Connector type: SFP+ male to SFP+ male
Length: 0.5 meter
Cable type: passive twinax copper (DAC)
Supported data rate: up to 10 Gbps (10GBase‑CR)
Wire gauge: 30 AWG twinax conductor
MSA‑compliant electrical and mechanical characteristics for SFP+ interfaces
How to use
Install the BlueOptics DAC‑0.5M‑EX‑BL by inserting each SFP+ connector into the SFP+ ports of the corresponding devices until the retention latch engages. Ensure both ends are seated firmly and that connected devices support passive SFP+ DAC cables. No external power or transceivers are required; protocol support (Ethernet, FCoE, etc.) must be enabled and configured on the connected hardware according to the device manufacturer’s instructions.
Usage recommendations
Use this 0.5 m passive DAC for short, fixed links inside racks or between adjacent racks to minimize latency and power draw. Avoid sharp bends and excessive mechanical strain on the cable and keep the cable path clear of heat sources. Verify device compatibility with passive SFP+ twinax DACs before deployment and follow rack‑level grounding and cable management practices to maintain signal integrity and accessibility.
