InfiniBand/fibre optic cable SFP28 BlueOptics TAPCABLE28-3M 3m Male/Male

The BlueOptics TAPCABLE28-3M is a 3-metre InfiniBand/fibre optic cable with SFP28 connectors on both ends, designed for high-speed data transmission in modern network infrastructures. This cable supports short-range, high-bandwidth links between switches, servers and storage devices where SFP28 ports are used. The male-to-male termination ensures direct compatibility with SFP28 transceivers and devices that accept standard SFP28 modules, providing a straightforward physical connection for high-throughput environments.

Advantages

The cable provides a reliable, low-latency connection suitable for high-performance computing and enterprise networking. Its SFP28 interface enables 25 Gb/s class speeds, while the 3-metre length balances reach and signal integrity for rack-to-rack or within-rack connections. The blue jacket aids visual identification in structured cabling environments and the fibre optic medium reduces electromagnetic interference compared with copper alternatives.

Suitable for

• Connecting servers, switches and storage with SFP28 ports in data centers
• Short-range interconnects in rack rows and within server cabinets
• High-performance computing (HPC) clusters and InfiniBand fabric links
• Enterprise network upgrades requiring 25 Gb/s optical links

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 3 metres
• Media type: fibre optic
• Intended data rate: compatible with 25 Gb/s class SFP28 links
• Application: short-range optical interconnects (within racks or between adjacent racks)
• Cable jacket colour: blue

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on your devices until the connector latches. Confirm port link status and negotiate speed according to the connected transceivers and switch configuration. Route the cable to avoid tight bends and mechanical strain, keeping bend radius and rack airflow considerations in mind. For mixed vendor environments ensure device compatibility with standard SFP28 modules before deployment.

Recommendations

For optimal performance, use this 3-metre fibre optic cable for short-reach links such as within-rack or adjacent-rack connections. Avoid sharp bends and excessive pulling force during installation, and maintain cleanliness of connectors to prevent signal loss. Verify that connected equipment supports SFP28 optics and appropriate link speeds prior to production use.
