ASY-05227-04 Arista 200G to 400G Bypass Transceiver

ASY-05227-04 Overview

The Arista ASY-05227-04 is a specialized 200G to 400G bypass transceiver designed for high-speed optical networking environments, particularly in modern data centers and large-scale enterprise backbones. Its primary role is to maintain optical link continuity during maintenance, failure, or device swaps—allowing network traffic to bypass an inactive or powered-down device without disruption. Supporting both 200Gbps and 400Gbps operation, it ensures flexible deployment in evolving network architectures. With a likely QSFP-DD interface, hot-pluggable design, and low power usage, this module provides a practical solution for operational uptime and rapid failover in mission-critical environments.
