BlueOptics CAB-S-S-25G-50CM InfiniBand fibre optic cable 0.5 m SFP28

The BlueOptics CAB-S-S-25G-50CM InfiniBand fibre optic cable 0.5 m SFP28 is a short-reach duplex cable engineered for high-speed interconnects in data centres and professional networking racks. With SFP28-compatible male connectors on each end and a 0.5 metre length, this fibre optic cable supports low-latency, high-throughput connections between switches, servers and storage devices where compact cabling and signal integrity are required.

Advantages

This InfiniBand fibre optic cable provides consistent 25G-class performance suitable for modern server and switch ports. The SFP28 connector format ensures compatibility with a wide range of SFP28 transceivers and ports, while the short 0.5 m length minimises signal attenuation and cable clutter in dense rack environments. The duplex construction maintains correct transmit/receive pairing and the cable is designed for professional networking use, offering stable optical performance and simple plug-and-play installation.

Suitable for

• Short-reach connections between servers and top-of-rack switches
• Direct cabling in data centre patch panels and networking racks
• High-speed storage area network links and clustering
• Equipment setups requiring SFP28 InfiniBand-compatible interconnects

Key specifications

• Connector type: SFP28 male to SFP28 male duplex
• Length: 0.5 m
• Technology: InfiniBand / fibre optic duplex
• Data rate class: designed for 25G-class high-speed links
• Duplex configuration: two fibres for transmit and receive

How to use

Insert each SFP28 connector into compatible SFP28 ports on network devices, ensuring correct orientation and secure seating until the latch engages. Use the cable for direct server-to-switch or switch-to-switch connections within the specified 0.5 m length to reduce link loss. Verify link status and port configuration on connected devices; if required, check transceiver compatibility and optical settings in device firmware or management software.

Recommendations

Route the cable to avoid sharp bends and excessive tension; maintain recommended bend radii for fibre optic cables. Keep connector endfaces clean and protected until installation to prevent signal degradation. For best results in dense racks, use short patch lengths like this 0.5 m cable to minimise patch panel congestion and optimise airflow.
