Product Overview

The QA11-4E8-xxM-C1 is a QSFP-DD active optical cable (AOC) designed for 400 Gigabit Ethernet applications. It supports high-speed data transmission over integrated multimode fiber with cable lengths ranging from 1m to 7m.

The module supports 8 parallel optical channels, each operating at 26.56GBaud, and complies with QSFP-DD MSA and CMIS 4.0 specifications. It provides CML-compatible electrical interfaces with integrated clock and data recovery (CDR) for reliable high-speed performance.

The transceiver assembly operates at 26.56GBaud per channel and supports short-reach interconnects for data center and high-performance computing environments.

The module operates from a single 3.3V power supply and is available in commercial operating
temperature range (0°C to +70°C). It is suitable for high-speed data center interconnects and short-reach
400G optical communication links.
