BlueOptics Q28-AOC-7M-MA-BO InfiniBand optický kábel 7 m QSFP28

The BlueOptics Q28-AOC-7M-MA-BO InfiniBand fibre optic cable is a 7-metre active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for short-distance high-speed links inside and between server racks. It uses OM3 multimode fibre with a 50 µm core diameter and LSZH (low smoke zero halogen) sheathing. The cable integrates optical transceiver modules at both ends that convert electrical signals to optical and back, enabling 100GBASE-SR4 and other QSFP28 applications where low weight, improved bend radius and hot-pluggable connectivity are required.

Advantages

This AOC provides lower weight and greater flexibility compared with direct-attach twinax solutions, and the integrated I/O and O/E converters simplify installation and compatibility with QSFP28 ports. The OM3 multimode fibre and QSFP28 transceiver modules support short-reach 100G data rates with reduced signal loss and improved thermal performance. The cable’s LSZH jacket reduces toxic emissions in case of fire, and all transceiver assemblies are manufactured to MSA and SFF/IEEE specifications and tested for quality and interoperability.

Suitable for

• Inter-rack and intra-rack 100 Gb/s connections in data centres
• High-performance computing clusters requiring InfiniBand/QSFP28 links
• Switch-to-switch and switch-to-server short-reach connections
• Environments where reduced cable weight and small bend radius are beneficial

Key specifications

• Length: 7 metres
• Connector type: QSFP28 to QSFP28 (active optical ends)
• Fibre type: OM3 multimode fibre
• Core diameter: 50 µm
• Supported standard: 100GBASE-SR4 and QSFP28 interfaces
• Sheathing: LSZH (low smoke zero halogen), flame resistant
• Hot-pluggable design with integrated optical/electrical conversion

How to use

Ensure both devices support QSFP28 SFF-compliant ports and are powered down or ready for hot-plugging according to your equipment manual. Align the QSFP28 connector keyed latch with the port receptacle and gently insert until the connector latches. For removal, depress the latch mechanism and pull the connector straight out. Route the cable to avoid sharp bends and secure it using rack cable management to maintain the recommended bend radius. No separate transceivers or patch cords are required; the cable provides integrated conversion and should be recognized by compliant QSFP28 ports.

Recommendations

Handle the cable by the connector housings, avoid twisting or crushing the fibre jacket, and maintain minimum bend radius to preserve optical performance. Verify compatibility with your QSFP28 ports and update firmware if required by your network equipment vendor. For installations in public or enclosed spaces, the LSZH jacket reduces toxic smoke in the event of fire and is recommended where halogen-free cabling is required.
