Product Description
The HP 845966-B21 is a high-performance 100 Gigabit Ethernet QSFP28 (Quad Small Form-factor Pluggable 28) optical transceiver module. It is specifically designed for short-reach applications within data centers, adhering to the 100GBase-SR4 standard. This standard utilizes four parallel lanes of 25Gb/s optical signals, each operating at 850nm, transmitted over multi-mode fiber (MMF) using a single MPO (Multi-fiber Push On) connector. This transceiver provides high-density, high-bandwidth connectivity for switches, servers, and other networking equipment. It supports distances of up to 100 meters when used with OM4 multi-mode fiber, making it ideal for intra-data center links, high-performance computing (HPC) clusters, and other applications requiring massive data throughput over short distances. The use of an MPO connector is characteristic of parallel optics, allowing for the aggregation of multiple fiber strands within a single connector for simplified cabling and higher port density. As a Hewlett Packard (HP) product, the 845966-B21 is optimized for performance and reliability within HP networking infrastructure, while also complying with industry standards for broad interoperability. Its QSFP28 form factor enables efficient use of rack space and power in demanding data center environments.
