BlueOptics BO282803L3M-BO InfiniBand optický kabel 3 m QSFP28 samec samec

The BlueOptics BO282803L3M-BO InfiniBand fibre optic cable 3 m QSFP28 Male Male is a 3-metre multimode fibre assembly with QSFP28 connectors at both ends, engineered for high-speed data transmission in data centres and high-performance computing environments. Its male-to-male QSFP28 termination supports direct connections between compatible QSFP28 ports and enables low-latency links for switch-to-switch, server-to-switch or switch-to-storage interconnects. The cable is intended for short-reach InfiniBand or Ethernet links that require reliable signal integrity and consistent optical performance.

Advantages

This QSFP28 fibre cable provides a compact, standardized connection with predictable optical characteristics and low insertion loss. The 3 m length offers flexibility for rack and cabinet layouts while minimizing excess cable management. With QSFP28 terminations on both ends, it simplifies deployment in environments that use QSFP28 ports for 100 Gigabit-class or InfiniBand HDR/EDR links. The cable's multimode fibre properties are suitable for short-range, high-bandwidth connections where stable throughput and low latency are priorities.

Suitable for

• Short-reach InfiniBand links in HPC clusters
• 100 Gigabit-class QSFP28 connections between switches and servers
• Interconnects in data centre racks and server cabinets
• High-throughput storage area network (SAN) connections

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Fibre type: multimode optical fibre (short-reach)
• Application: InfiniBand and high-speed Ethernet interconnects
• Typical use: rack and cabinet patching for high-bandwidth links

How to use

Identify two compatible QSFP28 ports on networking equipment or adapters and ensure both devices are powered down or follow hot-plug guidance from the equipment vendor. Align the QSFP28 plugs with the port openings and insert the connectors until they seat firmly. After connection, verify link status through management interfaces or indicator LEDs. Route the cable to avoid sharp bends and excessive tension; maintain the minimum bend radius recommended for multimode fibre to preserve optical performance.

Recommendations

Store and handle the cable in a clean environment, avoid contaminating connector endfaces, and clean connectors with appropriate fibre optic cleaning tools before insertion. Use proper cable management in racks to prevent strain and maintain recommended bend radii; perform link verification after installation to confirm expected performance.
