400G Optical Transceiver/Technology Overview
Brand: General/Industry Standard · SKU: 400G-GENERAL · MPN: Not Available · Category: Networking
400G primarily refers to optical networking technology capable of transferring data at speeds up to 400 Gigabits per second (Gbps) on a single optical wavelength, often realized through 400GbE (400 Gigabit Ethernet) standards. These modules are essential for modern high-performance environments like large data centers, cloud computing, high-performance computing (HPC), and AI workloads, offering a fourfold increase in capacity over 100G links. Common form factors include QSFP-DD (Quad Small Form-factor Pluggable Double Density) and OSFP (Octal Small Form-factor Pluggable). The technology relies on advanced modulation techniques like PAM4 (Pulse Amplitude Modulation 4-Level) to achieve high data rates. Various types exist based on distance and fiber, such as SR8 (Short Reach), DR4 (Intermediate Reach), FR4 (Long Reach), and LR4 (Extended Reach).

Key Features
400G technology is the next generation of high-speed optical transceivers designed to meet exploding bandwidth demands from AI, cloud, and massive data center traffic. It offers superior efficiency (power per bit) and density compared to aggregating multiple 100G links. The QSFP-DD form factor is a dominant industry choice, utilizing eight electrical lanes operating at 50 Gbps each with PAM4 modulation to aggregate to 400 Gbps.
