Product Description
The HP JH991AR is a 25Gb/s SFP28 (Small Form-Factor Pluggable 28) optical transceiver module, specifically designed to meet the increasing bandwidth demands of modern data centers and high-performance computing environments. This module enables high-speed network connections over multimode fiber (MMF) infrastructure, offering a significant upgrade path from traditional 10Gb/s Ethernet. It supports the 25GBase-SR standard, providing a cost-effective solution for short-reach applications within racks or between adjacent racks. Featuring a duplex LC connector, the JH991AR ensures a secure and reliable physical interface for multimode fiber optic cables. It operates at a wavelength of 850nm and is capable of transmitting data at 25 Gigabits per second over distances of up to 100 meters, typically utilizing OM3 or OM4 multimode fiber. The SFP28 form factor is backward compatible with SFP+ ports in some configurations, offering flexibility in network upgrades. Its hot-pluggable design allows for easy installation and replacement without interrupting network operations. This transceiver is a critical component for high-density server connectivity, network aggregation, and storage area networks (SANs) where high throughput and low latency are paramount. The HP JH991AR provides the performance necessary to support demanding applications such as big data analytics, artificial intelligence (AI), machine learning (ML), and cloud computing, enabling data centers to scale efficiently and cost-effectively.
