Description
The Juniper QDD-2X400G-DR4 is a high-performance optical transceiver module designed for data center and high-capacity networking environments. This QSFP-DD (Quad Small Form-factor Pluggable Double Density) module supports two independent 400 Gigabit Ethernet DR4 links, enabling a total aggregate throughput of 800 Gbps. Built for scalability and efficiency, it utilizes parallel single-mode fiber (PSM4) technology and operates over a distance of up to 500 meters using MPO-12 connectors. Its hot-swappable design allows seamless integration into compatible Juniper platforms, minimizing downtime during upgrades or replacements.
Engineered for demanding workloads, the QDD-2X400G-DR4 supports 8x 100G PAM4 electrical lanes per port, ensuring high-speed data transmission with low latency. The module complies with IEEE 802.3bs standards and is optimized for low power consumption, typically drawing less than 12W per port. It features robust diagnostics and digital monitoring capabilities, including real-time temperature, voltage, and optical power readings. Ideal for hyperscale data centers and cloud infrastructure, this transceiver provides reliable, high-density connectivity in a compact form factor.
