## Summary description

The BlueOptics CAB-S-S-25G-1M-BL is a 1 meter InfiniBand/fibre optic cable featuring SFP28 connectors on both ends. Designed for high-speed data transfer, this cable ensures reliable connectivity in data centers and networking applications. Its male-to-male configuration makes it versatile for various setups.

## Long description

The BlueOptics CAB-S-S-25G-1M-BL is a 1 meter SFP28-to-SFP28 direct attach cable designed for short-range high-speed links in racks and between adjacent racks. As a passive 25GBase-CR twinax copper assembly with 30 AWG conductors, it provides a compact, low-power physical connection compatible with devices that support 25GBase-CR and SFP28 interfaces. The cable is intended for use in data center environments, network switches, routers and storage systems where reliable 25 Gbps electrical connectivity is required over a 1 m distance.
Advantages
This SFP28 male-to-male cable offers predictable electrical performance for 25 Gbps applications while consuming minimal power because it is a passive direct attach cable. The twinax construction with 30 AWG conductors reduces insertion loss over the 1 m span and supports low latency links. Manufactured to industry MSA guidelines and assembled with quality components, the cable is suitable for continuous operation in dense rack environments and simplifies short-distance connectivity without transceivers.
Suitable for
Connecting switches and servers within the same rack or adjacent racks
Direct 25 Gbps links for top-of-rack and leaf-spine architectures
Storage array connectivity and host bus adapter links supporting SFP28
FCoE, Ethernet and InfiniBand-compatible short-reach electrical links where 25GBase-CR is supported
Key specifications
Length: 1 meter
Connector type: SFP28 male to SFP28 male
Data rate: up to 25 Gbps per channel
Cable type: passive twinax copper (Direct Attach Cable)
Conductor gauge: 30 AWG
Compliance: MSA-compliant SFP28 mechanical/electrical interface
Typical use: short-range rack-level interconnects
How to use
Insert each SFP28 plug into the corresponding SFP28 port on your network device until the latch engages. Ensure both devices support passive 25GBase-CR DAC cables and that firmware or driver compatibility is met. Route the cable to avoid sharp bends and avoid placing it under strain; maintain recommended bend radius for twinax assemblies. After physical connection, verify link status in the devices' management interfaces and run link tests or diagnostics as required by your deployment procedures.
Usage recommendations
Use this 1 m passive SFP28 DAC for short, rack-level connections where low latency and low power consumption are priorities. Confirm device compatibility with passive twinax DACs and keep the cable free from kinks, high mechanical stress and strong electromagnetic sources to maintain optimal signal integrity and long-term reliability.
