## Summary description

The BlueOptics 1NT7G-BL is a 5 m InfiniBand/fibre optic cable featuring SFP28 connectors. Designed for high-speed data transmission, it ensures reliable performance in data centers and networking environments. The male-to-male configuration allows for easy connectivity between devices, making it ideal for various applications.

## Long description

The BlueOptics InfiniBand/fibre optic cable 5 m SFP28 Male/Male 1NT7G-BL is a 5 metre, SFP28-terminated direct attach twinax cable designed for short-distance, high-speed interconnects in racks and between adjacent racks. It supports 25GBase-CR electrical signalling and is compatible with hardware platforms that accept SFP28 direct attach cables. The cable is intended for data centre and networking environments requiring low-latency, high-throughput connections between switches, routers, servers and storage systems.
Advantages
This direct attach twinax cable provides up to 25 Gbit/s per lane over a 5 m distance while remaining passive, which reduces power consumption and latency compared with active optical transceivers. The SFP28 male-to-male configuration enables plug-and-play connectivity for standard SFP28 ports. Manufactured to MSA-compliant mechanical and electrical specifications and built from high-quality components, the cable offers consistent signal integrity and a long service life suitable for professional installations.
Suitable for
High-speed server-to-switch or switch-to-switch connections within racks
Short-distance links between adjacent racks in data centres
Connections for storage systems, routers and InfiniBand-ready equipment
Environments requiring low-latency, energy-efficient interconnects
Key specifications
Length: 5 metres
Connector type: SFP28 male to SFP28 male
Rated throughput: up to 25 Gbit/s (25GBase-CR)
Cable type: passive twinax (copper) suitable for short-reach electrical signalling
Conductor gauge: 30 AWG
Industry compliance: MSA-compliant SFP28 mechanical/electrical interface
How to use
Ensure both devices have SFP28 ports that support passive DAC twinax cables and that their firmware or software allows passive connections. Align the SFP28 connectors with the ports and insert each end until the latch engages. Verify link status through the connected devices' management interface or indicator LEDs. For removal, depress the latch and withdraw the connector straight out to avoid stressing the cable or port. Use appropriate cable routing to prevent sharp bends and mechanical strain near the connectors.
Usage recommendations
Position the cable to avoid tight bends and keep it away from sources of mechanical abrasion or heat. Use the 5 m length for intra-rack and adjacent-rack connections where passive twinax is supported. Confirm device compatibility before installation and consider ordering a test sample if integration with specific hardware and software environments needs verification.
