## Summary description

The BlueOptics 25G-SFP28-TWX-P-0301-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors. It features a male/male configuration, designed for high-speed data transmission in networking applications. Ideal for connecting devices in data centers and enterprise networks, ensuring reliable performance and minimal signal loss.

## Long description

The BlueOptics 25G-SFP28-TWX-P-0301-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors in a male-to-male configuration. Designed for short-reach, high-speed interconnects, this 25GBase-CR compatible direct attach cable (DAC) supports data rates up to 25 Gbit/s over a 3 meter distance and is intended for linking switches, routers, servers and storage systems in racks and adjacent rack rows. The cable uses twinax copper construction with 30 AWG conductors and complies with relevant MSA physical interface specifications to ensure consistent electrical performance for Ethernet, FCoE, Fibre Channel and InfiniBand applications.
Advantages
The cable offers a passive twinax design that does not require active components, resulting in low power consumption and low latency suitable for short-distance connections. Components are selected to meet MSA standards and common vendor platform requirements, providing reliable signal integrity and long operational lifetime. The 3 m length and SFP28-to-SFP28 form factor allow straightforward, tool-free connections inside racks and between adjacent racks while minimizing signal loss and crosstalk typical for copper DACs.
Suitable for
 Short-reach connections between switches and routers within racks
 Server-to-switch links in data center top-of-rack or middle-of-row configurations
 Storage system connections and Fibre Channel/InfiniBand short links
 Environments where low-latency, low-power passive 25G links are required
Key specifications
 Connector type: SFP28 male to SFP28 male
 Length: 3 meters
 Data rate: up to 25 Gbit/s
 Cable type: passive twinax copper (DAC), 30 AWG conductors
 Supported protocols: Ethernet, FCoE, Fibre Channel, InfiniBand (up to 25G)
 Form factor: direct attach cable for short-distance rack connectivity
 Compliance: MSA-compliant physical interface
How to use
Connect each SFP28 plug to the SFP28 port of the network devices to be linked, ensuring proper orientation and a secure seating in the transceiver slot. Use within the specified 3 m distance for optimal signal integrity and verify that the connected hardware supports passive DAC connections and the 25GBase-CR electrical protocol. No additional power or configuration on the cable itself is required; any necessary link negotiation or protocol settings must be handled by the connected devices and their firmware or operating system.
Usage recommendations
Install the cable in a clean, strain-free path inside the rack to avoid sharp bends and mechanical stress; maintain the minimum bend radius specified by the device or cable vendor. Confirm compatibility with the target hardware platform before deployment and, where possible, test a sample link to validate performance and link stability in your environment.
