Cable de fibra óptica InfiniBand BlueOptics 720-084606-BL 5 m SFP28 conector macho/macho

The BlueOptics 720-084606-BL is a 5 m InfiniBand/fibre optic solution with SFP28 male connectors on both ends. Engineered for short-range, high-speed links in racks and adjacent-rack environments, this cable supports 25G data rates and is suitable for connecting switches, routers, storage systems and other SFP28-capable devices. The cable is a passive 25GBase-CR direct attach solution using twinax construction with 30 AWG conductors, designed to transmit electrical signals reliably over a 5 metre distance while conforming to MSA guidelines.

Advantages

The cable provides a straightforward, low-latency connection for short-distance links with minimal power consumption because it is a passive direct attach cable. Built to MSA-compatible specifications, it offers broad hardware compatibility with devices that support SFP28 25GBase-CR connections. The twinax design and quality components deliver stable signal integrity for Ethernet, FCoE and InfiniBand applications up to 25 Gbit/s across the specified 5 m span. The construction and component selection aim for extended operational lifetime and reduced maintenance needs.

Suitable for

• Short-range rack-to-rack or intra-rack 25G connections
• Switch-to-switch, switch-to-storage or switch-to-server links using SFP28 ports
• Data centre and networking environments requiring passive DAC twinax solutions
• Environments using Ethernet, FCoE or InfiniBand at up to 25 Gbit/s

Key specifications

• Cable type: passive twinax direct attach cable (DAC)
• Connector type: SFP28 male to SFP28 male
• Length: 5 metres
• Data rate support: up to 25 Gbit/s
• Conductor gauge: 30 AWG
• Standards: MSA-compliant SFP28 25GBase-CR transmission

How to use

Insert each SFP28 connector into the corresponding SFP28 port on the networking devices until the latch engages. Ensure both devices support passive 25GBase-CR DAC operation and that the ports are enabled and configured for the intended protocol (Ethernet, FCoE or InfiniBand). Route the 5 m cable within racks or between adjacent racks avoiding sharp bends and excessive tension. Verify link status and network configuration after connection and monitor for expected throughput and latency.

Recommendations

Use this passive SFP28 DAC for short-distance links where low latency and low power consumption are required. Avoid using passive twinax DACs over distances beyond the specified 5 m and confirm device compatibility with passive 25GBase-CR cabling according to the hardware vendor documentation before deployment.
