Product Description
The Juniper QDD-2X100G-LR4 is a cutting-edge optical transceiver module designed to meet the escalating demands for bandwidth in modern data centers and high-performance networks. This QSFP-DD (Quad Small Form-factor Pluggable Double Density) module enables 200 Gigabit Ethernet connectivity, aggregating four independent 50 Gigabit lanes to achieve the total 200 Gb/s throughput. It adheres to the 200GBase-LR4 standard, which specifies operation over single-mode fiber at a wavelength of 1310nm. The 'LR4' designation indicates that the module uses four different wavelengths (each carrying 50Gbps) multiplexed together for transmission over a single pair of single-mode fibers, enabling extended reach capabilities. This specific module is designed for distances up to 10 kilometers, making it suitable for data center interconnects (DCI), campus backbones, and other long-reach applications where high bandwidth is critical. The use of single-mode fiber allows for lower signal degradation over longer distances compared to multi-mode fiber. Equipped with LC duplex connectors, the QDD-2X100G-LR4 is designed for integration into compatible QSFP-DD ports found on high-end Juniper routers and switches, as well as other networking equipment supporting this form factor. Its high density and performance make it an essential component for network architects looking to scale their infrastructure to support the massive data flows generated by cloud computing, big data analytics, and high-frequency trading.
