Product Description
The Juniper QDD-4X100G-LR is a high-performance optical transceiver module designed to meet the growing demand for 400 Gigabit Ethernet connectivity in data centers and service provider networks. This QSFP28 module aggregates four independent 100Gb/s optical channels, delivering a total aggregate bandwidth of 400Gb/s. It is specifically engineered for Long Reach (LR) applications, utilizing a 1310nm wavelength laser, which is ideal for transmitting data over extended distances on single-mode fiber optic cables. This transceiver is compliant with industry standards such as IEEE 802.3bm and the QSFP28 Multi-Source Agreement (MSA), ensuring interoperability with a wide range of networking equipment that supports this form factor. The QDD-4X100G-LR is designed for deployment in environments requiring robust, high-capacity links, such as data center interconnects, core network aggregation, and high-performance computing clusters. Its ability to transmit up to 10 kilometers over single-mode fiber makes it a versatile solution for connecting geographically dispersed network segments. As a hot-swappable module, the QDD-4X100G-LR can be installed or replaced without interrupting network traffic, facilitating ease of deployment and maintenance. The module's advanced optical technology ensures reliable signal integrity and performance, making it a key component for building scalable and efficient high-bandwidth networks. It typically connects to compatible QSFP-DD ports on routers and switches, providing a high-density solution for 400GbE connectivity.
