## Summary description

The BlueOptics CBL-NTWK-0944-SS28C30M-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors. It features male-to-male connectivity, ensuring high-speed data transmission for networking applications. Ideal for data centers and high-performance computing environments.

## Long description

The BlueOptics CBL-NTWK-0944-SS28C30M-BL is a 3 m InfiniBand/fibre optic cable with SFP28 male-to-male connectors designed for short-reach, high-speed links. It supports 25GBase-CR direct attach connections and is suited for rack-to-rack or in-rack connections where reliable, low-latency data transmission is required. The cable follows MSA-compliant SFP28 form-factor guidelines and is compatible with hardware platforms that accept SFP28 direct attach twinax or similar 25 G electrical interfaces.
Advantages
The cable provides a straightforward passive direct attach solution with low power consumption and minimal latency for short-distance interconnects. Construction uses high-quality twinax copper and industry-standard components to deliver consistent electrical performance over the specified 3 m length. Compatibility with common switches, routers and storage systems that support SFP28 direct attach modules enables flexible deployment in data center and high-performance computing environments.
Suitable for
 Rack-to-rack and in-rack networking within data centers
 25G Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand short links
 Switch-to-switch, switch-to-server and switch-to-storage connections
Key specifications
 Length: 3 meters
 Connector type: SFP28 male to SFP28 male
 Data rate support: up to 25 Gbit/s per link (25GBase-CR)
 Cable type: passive twinax copper (30 AWG)
 Form factor compliance: SFP28, MSA-compliant
 Typical power consumption: low passive operation (~0.1 W per link when applicable)
How to use
Insert each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring proper orientation and a secure latch. Use this 3 m direct attach cable for short, point-to-point electrical connections between compatible network equipment; no external power or transceiver modules are required for passive operation. Verify that the connected devices support passive DAC or SFP28 direct attach connections at 25GBase-CR to ensure link negotiation and correct signalling.
Usage recommendations
For reliable operation, avoid sharp bends and excessive strain on the cable; maintain bend radii recommended by the equipment vendor. Confirm device compatibility and firmware support for passive SFP28 direct attach cables before deployment. For critical links, test the cable in your environment to verify link stability and performance.
