How Much Do you Know About 400G FR4 QSFP-DD Module?
What is a 400G FR4 QSFP-DD module?
The 400G FR4 QSFP-DD module (Cisco model QDD-400G-FR4-S) is a high-performance fiber optic module that supports data transmission rates up to 400Gbps. It uses a QSFP-DD (Quad Small Form Factor Pluggable Double Density) interface and is suitable for network devices that require large bandwidth and high-speed connections. FR4 represents an optical module standard, which usually refers to the module’s transmission capability within a range of 2 kilometers and is mainly used for long-distance data transmission.
The module usually uses single-mode fiber (SMF) and transmits data to remote devices through built-in modulation technology. It is suitable for scenarios with long-distance high-speed transmission requirements such as data centers and metropolitan area networks. Due to its double-density design, the 400G QSFP-DD interface provides more connection density than the standard QSFP28 interface, thereby better meeting the needs of modern high-bandwidth networks.
