## Summary description

The BlueOptics CBL-NTWK-0944-MS28C30M-BL is a 3 m InfiniBand/fibre optic cable with SFP28 connectors. It features male-to-male connectors for reliable data transmission. Ideal for high-speed networking applications, this cable ensures optimal performance and connectivity in data centers and enterprise environments.

## Long description

The BlueOptics CBL-NTWK-0944-MS28C30M-BL is a 3 m InfiniBand/fibre optic direct attach cable with SFP28 male-to-male connectors designed for short-reach, high-speed links. It supports 25GBase-CR systems and is suitable for connecting rack-mounted equipment and adjacent racks where low latency and reliable data transmission are required. The cable is manufactured to MSA-compliant specifications and is available in a black and silver finish. It weighs approximately 0.13 kg and uses 30 AWG twinax construction for electrical signal transmission over a 3 m distance.
Advantages
This 3 m SFP28 cable delivers a compact and low-power connectivity option for 25 Gbit/s links with minimal latency and low insertion loss. As a passive direct attach twinax cable, it requires no additional power and offers straightforward plug-and-play installation on hardware that supports passive DACs. Built to industry MSA standards with quality subcomponents, the cable provides consistent compatibility with major networking platforms when the host devices support the specified 25GBase-CR protocol.
Suitable for
Connecting switches and routers within the same rack or adjacent racks
High-speed server-to-switch connections in data centres
Storage system links and SAN interconnects supporting 25G
InfiniBand and Fibre Channel short-reach links up to 25 Gbit/s
Key specifications
Cable length: 3 m
Connector type: SFP28 male to SFP28 male
Supported protocol: 25GBase-CR (up to 25 Gbit/s)
Cable construction: passive twinax, 30 AWG
Colour: black and silver
Weight: approx. 0.13 kg
How to use
Ensure both host devices explicitly support passive SFP28 direct attach (DAC) twinax cables and the 25GBase-CR transmission standard. Power down or follow hot-swap procedures recommended by the hardware vendor before inserting the SFP28 connectors. Align each SFP28 plug with the port and insert until it seats firmly; secure any retention mechanism provided by the port. For removal, release the port latch and withdraw the connector straight out. Verify link status through the equipment management interface after installation.
Usage recommendations
Use this cable for short-distance connections (up to 3 m) inside racks or between adjacent racks. Avoid tight bends, excessive twisting, and exposure to mechanical stress; maintain the manufacturer’s minimum bend radius for twinax construction. Confirm hardware compatibility with passive DACs and the 25GBase-CR protocol to ensure reliable operation.
