BlueOptics JL272A-BL InfiniBand fibre optic cable 3 m QSFP28 Male Male

The BlueOptics JL272A-BL InfiniBand fibre optic cable is a 3 m QSFP28 Male-to-Male cable designed for high-speed data transmission in data centers and networking environments. It supports InfiniBand and related high-throughput protocols over a short 3-metre reach and is intended for use where low latency and reliable connectivity between QSFP28 ports are required.

Advantages

This QSFP28 fibre optic cable provides a standardized QSFP28 interface on both ends for straightforward connectivity with compatible switches, routers and storage systems. The 3 m length is suitable for rack-to-rack or intra-rack links while minimizing signal attenuation. The cable follows MSA-compliant connector and interface conventions to promote interoperability with hardware that supports QSFP28 and InfiniBand protocols.

Suitable for

• Short-reach interconnects between QSFP28 ports in data center racks
• High-bandwidth InfiniBand links for compute clusters and HPC
• Connections between switches, routers and storage devices with QSFP28 ports
• Low-latency links for virtualization, storage networking and database systems

Key specifications

• Cable type: multimode/mode appropriate for QSFP28 InfiniBand applications
• Connector type: QSFP28 Male on both ends
• Length: 3 metres
• Supported protocols: InfiniBand and other high-speed protocols compatible with QSFP28
• Typical use: short-reach, high-bandwidth interconnects in data centre environments

How to use

Identify QSFP28 ports on the devices to be connected and ensure they support the same protocol and speed. Align each QSFP28 connector with the port and insert until the connector latches. Verify link status through device management interfaces and monitor for proper negotiation and data transfer. For removal, release the latch and withdraw the connector straight out to avoid stress on the port.

Recommendations

Handle the cable by the connector housings and avoid tight bends; maintain the recommended minimum bend radius. Use this 3 m QSFP28 cable for short interconnects within or between adjacent racks and confirm device compatibility with QSFP28 InfiniBand links before deployment.
