High-performance 100G QSFP28 active optical cable for short-range data communication.
When high-speed interconnects in AI training clusters or data centers suffer from signal degradation over copper, active optical cables provide a reliable solution for short-range links. The LRAOC-QSFP28-3M addresses this by delivering stable 100Gbps bandwidth with low latency and power consumption, ensuring seamless data flow in dense server environments.
With a total bandwidth of 100Gbps across four channels, each operating at 25Gbps, this cable supports distances up to 70m on OM3 fiber or 100m on OM4 fiber. This eliminates the need for complex transceiver pairing and reduces power dissipation to less than 3.5W per end, enabling energy-efficient scaling of high-performance computing networks.
Ideal for IEEE 802.3bm 100GBASE-SR4 and Infiniband FDR/EDR applications, this QSFP28 AOC leverages reliable VCSEL array technology. Its hot-pluggable design and I2C management interface simplify deployment and monitoring, providing a robust, plug-and-play connectivity solution for modern data center infrastructure.
Delivers 100Gbps aggregate bandwidth with 25Gbps per lane for high-performance data center interconnects.
Supports up to 70m on OM3 and 100m on OM4 multimode fiber, ideal for rack-to-rack connections.
Consumes less than 3.5W per end, reducing cooling requirements and operational costs in dense deployments.
Compatible with 100G Ethernet, 40G Ethernet, 128G Fiber Channel, and Infiniband FDR/EDR applications.
Allows for easy installation and maintenance without powering down the host system.
