Description
The HPE 845966R-B21 is a remanufactured QSFP28 transceiver module designed to meet the high-bandwidth demands of modern data centers. Operating at 100Gbps, this module utilizes the SR4 standard, which employs four parallel transmit and four parallel receive lanes over multi-mode fiber. This configuration allows for efficient and high-density connectivity, typically used for links between top-of-rack switches or between switches and servers. The module features an MPO (Multi-fiber Push On) connector, which is essential for parallel optics as it houses multiple fiber strands within a single connector. The SR4 standard supports transmission distances of up to 100 meters over OM3 multi-mode fiber and up to 150 meters over OM4 multi-mode fiber, making it ideal for intra-data center links. As a remanufactured product, the 845966R-B21 provides a cost-effective and sustainable option for network infrastructure. Each unit undergoes a rigorous refurbishment process, including testing and quality assurance, to ensure it meets HPE's performance and reliability specifications. This makes it a dependable choice for organizations seeking to upgrade their data center network capabilities.
