BlueOptics InfiniBand/fibre optic cable 30 m QSFP28 Male/Male

The BlueOptics InfiniBand/fibre optic cable 30 m QSFP28 Male/Male is a 30-metre duplex optical cable designed for high-speed data transmission in data centres and high-performance computing environments. Equipped with QSFP28 male connectors on both ends, this fibre optic cable supports next-generation InfiniBand and high-bandwidth serial links where low latency and signal integrity are required. The cable's length and connector type make it suitable for inter-rack and intra-rack links where reliable, long-reach optical connectivity is needed.

Advantages

This 30 m QSFP28 male-to-male cable delivers consistent signal quality and stable throughput over longer distances compared with copper alternatives. The use of industry-standard QSFP28 connectors ensures broad compatibility with equipment that supports InfiniBand and 100GbE interfaces. The optical construction reduces electromagnetic interference and provides thermal stability in dense equipment racks.

Suitable for

• Interconnects between servers, switches and storage in data centre racks
• High-performance computing clusters using InfiniBand
• High-bandwidth links requiring low latency and high signal integrity
• Upgrading or expanding fibre-based network infrastructure

Key specifications

• Cable type: Fibre optic duplex
• Connector type: QSFP28 male to QSFP28 male
• Length: 30 m
• Application: InfiniBand and high-speed serial links (up to QSFP28/100 G class systems)
• Transmission medium: Optical fibre (single-mode or multimode as supported by QSFP28 systems)
• Immunity: Not affected by electromagnetic interference

How to use

Route the cable avoiding sharp bends and mechanical stress; adhere to minimum bend radius recommendations of your optical equipment. Insert QSFP28 male connectors firmly into the corresponding transceiver or port until the latch engages. Verify link status on connected devices and perform link tests if required. For long-term installations, secure the cable along cable trays or management channels to prevent movement and maintain connector alignment.

Recommendations

Use this 30 m QSFP28 fibre optic cable for direct optical links between compatible QSFP28 ports in data centre and HPC environments. Confirm port compatibility (InfiniBand or 100Gb-class interfaces) before deployment and follow equipment manufacturer guidelines for cleaning connectors and maintaining optical performance.
