Cavo in fibra ottica InfiniBand BlueOptics X66130-05-BL 0,5 m SFP28 nero

The BlueOptics X66130-05-BL is a 0.5 m InfiniBand/fibre optic cable with SFP28 connectors designed for short-range, high-speed interconnects in racks and adjacent rack systems. It combines a compact 0.5 metre length with SFP28 termination to support 25 Gbps class links for Ethernet, FCoE and InfiniBand-compatible applications. The cable’s black jacket provides a professional appearance while meeting mechanical requirements for typical data center and server-room environments.

Advantages

The cable provides a direct, low-latency link between SFP28 ports and is suitable for passive 25GBase-CR twinax copper or short-range optical connections depending on system support. Its MSA-compliant SFP28 terminations ensure wide compatibility with hardware platforms that support SFP28 modules, while the short 0.5 m length reduces signal loss and crosstalk in dense rack deployments. The durable outer jacket and well-matched components contribute to consistent performance and long service life.

Suitable for

• Interconnecting switches, routers and storage systems within the same rack or adjacent racks
• High-speed Ethernet links up to 25 Gbps, FCoE and InfiniBand-compatible links on short distances
• Server-to-switch connections in data centers and colocation facilities

Key specifications

• Length: 0.5 metre
• Connector type: SFP28 to SFP28
• Supported data rates: up to 25 Gbps per link (protocol dependent)
• Cable type: short-reach direct attach (twinax copper / short-range fibre options depend on system support)
• Wire gauge (for twinax copper variant): 30 AWG
• Jacket color: black
• MSA-compliant SFP28 interfaces for broad hardware compatibility

How to use

Confirm that both devices support SFP28 direct-attach or SFP28 fibre connections and the intended 25GBase-CR or equivalent protocol. With powered equipment turned off or following hot-plug safety guidelines for your hardware, insert each SFP28 connector into the corresponding SFP28 port until the latch engages. Route the 0.5 m cable to avoid sharp bends or tight cable management constraints that exceed manufacturer bend-radius recommendations. Power on the devices and verify link status and negotiated speed in the host or switch management interface.

Recommendations

Use the BlueOptics X66130-05-BL for short-distance, high-bandwidth connections where minimal latency and reduced signal loss are required. Ensure your network equipment supports passive DAC or the chosen short-range fibre signaling for 25 Gbps operation. Avoid exceeding specified bend radii, and inspect connectors before installation to prevent contamination-related signal issues.
