BlueOptics InfiniBand/glasvezelkabel 30 m QSFP28 aqua

The BlueOptics InfiniBand/fibre optic cable 30 m QSFP28 Aqua is a 30-metre active optical cable (AOC) with QSFP28 to QSFP28 connectors designed for high-speed links in data centres and professional network environments. It implements 100GBASE-SR4 multimode transmission over pre-assembled fibre, providing a ready-to-install connection that reduces patching and attenuation issues. The aqua-coloured jacket helps with cable identification while the integrated transmitter and receiver modules on each end support simultaneous send and receive optical signals according to MSA QSFP28 standards.

Advantages

The cable delivers 100 Gbit/s multimode optical transmission over 30 metres with support for Ethernet, Fibre Channel over Ethernet and other high-speed protocols. Being an active optical cable, it incorporates optical transceivers that eliminate the need for separate SFP/QSFP modules and reduce port density constraints. The pre-assembled fibre design reduces electromagnetic interference sensitivity, simplifies deployment and minimises signal loss compared with multiple patch connections. Digital diagnostic monitoring (DDM/DOM) capability is available for real-time status of voltage, laser bias current, optical output/input power and temperature when supported by connected hardware.

Suitable for

• 100G data centre uplinks between switches and routers
• High-performance computing clusters using InfiniBand or QSFP28 interfaces
• Storage area network (SAN) connections and switch-to-switch links
• Short-reach optical links within server rooms and equipment cabinets

Key specifications

• Connector type: QSFP28 to QSFP28
• Length: 30 metres
• Data rate: 100 Gbit/s (100GBASE-SR4 capability)
• Fibre type: multimode fibre (AOC)
• Colour: aqua (identification jacket)
• Integrated transmitter/receiver modules at both ends
• Digital diagnostics monitoring (DDM/DOM) support (MSA SFF-8472) when supported by host hardware

How to use

Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices until the latch engages. Ensure both ends are compatible with the host devices and that QSFP28 ports are enabled and configured for 100G operation if required by the equipment. Check device documentation for DDM/DOM support if you intend to monitor optical parameters. Route the cable to avoid sharp bends and secure it to prevent strain at connector ends; the pre-assembled design reduces the need for additional patch cords or cleaning of fibre endfaces.

Recommendations

Verify hardware compatibility and firmware/software settings of the connected devices before deployment. Maintain bend radius and mounting practices recommended for multimode AOCs, avoid exposure to mechanical stress and keep connectors capped when not in use. Use DDM/DOM diagnostics to monitor link health if supported by your switch or host system.
