Product Description
This Arista QDD-400G-SR8 transceiver represents a significant advancement in high-speed networking, delivering an aggregate bandwidth of 400 Gigabits per second. It employs the 8xQDD (Quad Small Form-Factor Pluggable Double Density) form factor, which allows for higher port density and increased throughput in modern network switches and routers. The module is optimized for short-reach applications, making it ideal for interconnecting equipment within a single rack or across adjacent racks in a data center. The transceiver operates at a wavelength of 850nm, leveraging multi-mode fiber (MMF) optics. It utilizes 8 parallel transmit and 8 parallel receive optical lanes, each operating at 50Gbps, to achieve the total 400Gbps capacity. This parallel architecture requires a 16-fiber MPO/MTP connector, enabling high-density cabling solutions. The SR designation indicates its suitability for distances typically up to 100 meters over OM3 or OM4 multi-mode fiber. Designed for the demanding environments of hyperscale data centers and high-performance computing clusters, the QDD-400G-SR8 provides the necessary bandwidth to support the ever-increasing traffic demands. Its integration into Arista's networking ecosystem ensures interoperability and performance, facilitating the deployment of next-generation network infrastructures.
