## Summary description

The BlueOptics SFP-H25G-CU50CM-BL is a 0.5m SFP28 cable designed for high-speed data transmission. It features male connectors on both ends, ensuring compatibility with SFP28 ports. Ideal for connecting devices in data centers or network environments, this cable offers reliable performance and durability.

## Long description

The BlueOptics SFP-H25G-CU50CM-BL 0.5m SFP28 Male/Male is a passive direct attach copper (DAC) twinax cable designed for short-reach 25G connections. With SFP28 connectors on both ends and a 0.5 meter length, this cable provides a straightforward electrical connection for servers, switches and storage devices that support SFP28 25GBase-CR interfaces. The product is intended for data center rack and adjacent-rack links where a compact, low-latency and low-power cabling solution is required.
Advantages
This SFP28 DAC cable offers native 25G data rate support over a short 0.5 m span with minimal latency and power consumption. The passive twinax construction simplifies installation and reduces points of failure compared with active optical or transceiver-based links. The cable's SFP28 male-to-male connectors ensure plug-and-play compatibility with equipment that accepts SFP28 modules, while its compact form factor is suitable for dense rack environments. The product colour options (black, silver) and low weight make handling and routing in congested racks easier.
Suitable for
 Short-reach 25G connections between adjacent rack units
 Direct links between switches, routers and servers with SFP28 ports
 High-density data center top-of-rack or middle-of-row cabling
 Storage and compute interconnects supporting 25GBase-CR

How to use
Install the BlueOptics SFP-H25G-CU50CM-BL by inserting each SFP28 connector into the corresponding SFP28 port on your networking devices until the latch clicks. Verify that both endpoints officially support passive 25GBase-CR direct attach cables. After physical installation, check link status and interface settings on each device to ensure the 25G link is negotiated and operating at the expected speed. For hot-plug capable equipment, you may insert or remove the cable while the systems are powered, following the vendor's hot-swap guidelines.
Usage recommendations
Use this cable for reliable short-distance electrical links inside racks or between adjacent racks. Confirm platform compatibility with SFP28 passive DACs before deployment and avoid sharp bends or excessive mechanical stress on the twinax assembly to preserve signal integrity and service life.
