About This Part
The Nokia 3HE15211AA is a high-performance QSFP-DD (Quad Small Form-factor Pluggable Double Density) optical transceiver, engineered for next-generation data center and enterprise networking environments. This module, part of Nokia's advanced optical solutions portfolio, adheres to the 400GBASE-SR8 standard, facilitating an aggregate data rate of 400 Gigabits per second (Gbps). It operates over eight parallel lanes, each transmitting at 50Gbps PAM4 modulation, utilizing multi-mode fiber (MMF) for short-reach applications. With a typical wavelength of 850nm, the Part Number 3HE15211AA is designed for reliable, high-density connectivity over distances up to 70 or 100 meters, depending on the OM3 or OM4 fiber type, respectively. Its QSFP-DD form factor ensures compatibility with a wide array of modern networking equipment, providing robust and efficient optical interconnects. This Nokia 3HE15211AA transceiver is primarily deployed within hyperscale data centers, cloud computing facilities, and large enterprise networks where high-bandwidth, low-latency interconnections are critical. It is installed in switches, routers, and network interface cards (NICs) equipped with QSFP-DD ports, enabling high-speed server-to-server, switch-to-switch, and spine-leaf architecture links. The module addresses the escalating demand for increased data throughput, supporting applications such as artificial intelligence (AI), machine learning (ML), high-performance computing (HPC), and real-time data analytics. By providing a seamless upgrade path from 100G or 200G infrastructures, it empowers telecom operators and data center providers to alleviate bandwidth bottlenecks, enhance network scalability, and future-proof their critical infrastructure against ever-growing traffic volumes.
