Avaya AA1404028-E6 Quadwire 40Gb QSFP Active Optical Cable

Avaya AA1404028-E6 Quadwire 40Gb QSFP Active Optical Cable is a 40GBASE-SR4 QSFP+ active optical cable (AOC) that uses four parallel 10 Gbps lanes to deliver 40 Gbps over multimode fiber. It features QSFP+ connectors on both ends and is designed for short-reach data-center interconnects, including switch-to-switch uplinks and high-density server-to-network connections that require hot-swappable, fiber-based 40 Gbps links. The unit transmits over 850 nm MMF with VCSEL-based transmission and is specified for a 10-meter link. In practice, it’s commonly used to connect QSFP+ ports in data-center switches and storage networks, offering a direct, cable-based 40 Gbps path without separate transceivers. Length: 10 meters (32.8 ft).
