InfiniBand/optický kábel BlueOptics 100G-Q28-Q28-C-00501-BL 0,5 m QSFP28 samec/samec

The BlueOptics 100G-Q28-Q28-C-00501-BL is a 0.5 m InfiniBand/fibre optic active cable with QSFP28 male-to-male connectors, engineered for up to 100 Gbps data transmission in dense networking and data center environments. It implements the QSFP28 AOC form factor and multi-mode optical transmission to provide a pre-assembled optical link that reduces connector handling and attenuation compared to patch-cord assemblies.

Advantages

This cable offers a compact, factory-terminated QSFP28 to QSFP28 connection that supports 100GBASE-SR4-class optical links over multimode fiber. Being an active optical cable (AOC), it integrates optical transceivers and drivers into the assembly to deliver consistent high-bandwidth performance with reduced electromagnetic interference. Built to industry MSA guidelines and using qualified components for lasers and ICs, it is intended to provide stable long-term operation and predictable interoperability with hardware that accepts QSFP28 AOCs.

Suitable for

• 100 Gbps switch-to-switch connections in data centers
• Server uplinks and top-of-rack interconnects
• High-performance computing and InfiniBand clusters
• Storage systems and SAN interconnects requiring low latency
• Short-reach optical links inside network racks or equipment rooms

Key specifications

• Connector type: QSFP28 male to QSFP28 male (pre-terminated AOC)
• Length: 0.5 m
• Data rate: up to 100 Gbps (100GBASE-SR4 compatible)
• Transmission medium: multimode fiber with integrated optical transceivers
• Form factor: QSFP28 AOC, MSA-compliant electrical/mechanical interface
• Supports digital diagnostics (DDM/DOM) for monitoring supply voltage, laser bias current, transmit/receive power and temperature (if supported by host)
• Low susceptibility to electromagnetic interference (optical link)

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 plug into the corresponding QSFP28 ports on host devices until the retention latch engages. Confirm that connected devices support QSFP28 AOCs and the intended 100G protocol (such as 100GBASE-SR4 or compatible vendor implementations). Monitor link status through host management interfaces and, if available, read DDM/DOM parameters to verify optical power and temperature during deployment. Handle the cable by its connector housings and avoid tight bends at the cable exit to maintain the minimum bend radius recommended for multimode AOCs.

Recommendations

Ensure compatibility with the specific switch, router or storage platform and verify that the host firmware or OS accepts third-party QSFP28 AOCs. Keep the cable free from sharp bends and secure it inside racks to prevent mechanical stress. Use DDM/DOM readings to assist troubleshooting and plan inventory using the 0.5 m length for short-reach top-of-rack or in-chassis connections.
