400G Optical Module for Security and Remote Monitoring
Cisco 400G QSFP-DD High-Power (Bright) Optical module's small size and low power make it an optimal choice for a wide range of DCI/Cloud, metro access/aggregation, wireless backhaul, and campus interconnect applications. First, let's clarify what VR, SR, DR, FR, LR, ER, and ZR stand for, so that we can understand and identify them: VR (Very Short Range): Transmission distance usually 0~100 meters, using multimode fiber for short data center connections. This article explores the enabling technologies, performance. Cisco is now expanding the range of 400G Digital Coherent QSFP-DD transceivers, introducing High Tx Power variants (+1dBm of Tx Power). The electrical signal is converted into an optical signal at the transmitter, which then travels through fiber optics, and is converted back to an electrical signal at the receiver. It is primarily applied in data center interconnect (DCI), AI clusters, large-scale cloud networks, and telecom backbones. Taking the QSFP-DD package as an example, its working principle is shown in the figure below.
