The 6A11-A0121-030.0-0 is a 3M Active Optical Cable Assembly for SFP+ Applications designed to deliver high-speed optical connectivity using industry-leading VCSEL technology. This module operates as a single bi-directional channel at data rates from 1 to 10.3125 Gbps with an operating optical wavelength of 850 nm, achieving a bit error rate (BER) of less than 10?¹² and supporting fiber links up to 100 meters. The assembly features low power consumption of 240 mW per end (typical), operates over a case temperature range of 0 to +70°C, and provides a 3.3V nominal supply voltage with a 20-pin edge connector electrical interface. It supports multiple protocols including InfiniBand, Ethernet, and Fiber Channel, with full diagnostic capabilities via Serial and I2C management interfaces, making it ideal for high-performance computing clusters, 10G Ethernet applications, and Fiber Channel deployments in servers, switches, and storage systems.
