Finisar Corporation FCBN410QB1C03 Active Optical Cable

The Finisar FCBN410QB1C03 Active Optical Cable (AOC) delivers 40 Gbps across four 10 Gb/s lanes with a QSFP+ to QSFP+ configuration, designed for high-speed links between switches, routers, and servers over short to medium distances in data centers, enterprise networks, and cloud infrastructure. This 3-meter, multimode-fiber cable features a plenum-rated jacket and QSFP+ connectors on both ends, enabling reliable, low-latency data transmission in dense rack environments. It draws power from a 3.3 V supply and typically uses under 1.5 W per end, with an operating temperature range from 0°C to +70°C. Compliance includes IEEE 802.3ba and SFF-8436, and its common applications cover high-speed Ethernet and InfiniBand connectivity between networking equipment, providing a compact, integrated optical solution for fast intra-data-center links.
