## Summary description

The BlueOptics CBL-NTWK-0944-MS28C10M-BL is a 1 m InfiniBand/fibre optic cable featuring SFP28 Male/Male connectors. It provides high-speed data transfer and reliable connectivity for networking applications.

## Long description

The BlueOptics CBL-NTWK-0944-MS28C10M-BL is a 1 m InfiniBand/fibre optic cable with SFP28 male-to-male connectors designed for short-range, high-speed connectivity. Built to support 25GBase-CR applications, this direct attach cable (DAC) implements a passive twinax copper design with 30 AWG conductors and SFP28 interfaces, offering low latency and low power consumption for rack-to-rack and within-rack links. The cable is MSA-compliant and intended for use with networking hardware that supports SFP28 direct attach connections.
Advantages
This 1 m SFP28 male/male cable provides reliable 25 Gbit/s data transfer for Ethernet, FCoE, Fibre Channel and InfiniBand protocols on short links. Passive twinax construction yields minimal power draw and latency while keeping physical complexity and failure points low. Manufacturing to MSA standards and the use of quality components ensure consistent electrical characteristics and long operational life suitable for data centre and enterprise environments.
Suitable for
Direct connections between switches and servers within the same rack or adjacent racks
High-speed links for storage arrays and storage networks
Short-range InfiniBand or 25G Ethernet interconnects in data centres
Upgrading or replacing SFP28 DAC links where 1 m cable length is required
Key specifications
Connector type: SFP28 male to SFP28 male
Length: 1 meter
Transmission rate: up to 25 Gbit/s
Cable type: passive twinax copper (DAC), 30 AWG conductors
Standards: MSA-compliant SFP28 direct attach
Typical applications: Ethernet, FCoE, Fibre Channel, InfiniBand
Power consumption: passive (very low, typically ~0.1 W at link)
How to use
Insert the SFP28 connectors into the corresponding SFP28 ports on your compatible switches, servers or storage devices until they latch. Ensure both devices support passive SFP28 DAC connections and the chosen protocol (for example 25GBase-CR for Ethernet). Route the cable to avoid sharp bends and mechanical strain; secure within the rack to prevent tugging on the connectors. No additional configuration is required at the physical layer beyond verifying link settings and supported speeds on connected equipment.
Usage recommendations
Verify hardware compatibility and port firmware support for passive 25G SFP28 DACs before deployment. Use the 1 m length for short, direct links inside racks or to adjacent racks. Avoid repeated excessive flexing and maintain minimum bend radius to preserve signal integrity.
