About This Part
The HP 845398-B21 is a high-performance SFP28 (Small Form-Factor Pluggable 28) optical transceiver module designed for 25 Gigabit Ethernet (25GbE) applications. This compact, hot-pluggable module facilitates robust, high-speed data transmission over multimode fiber optic cables. Operating at an 850nm wavelength, the Part Number 845398-B21 supports reliable connectivity for distances up to 100 meters, making it ideal for short-reach interconnections within data centers and enterprise networks. It conforms to industry standards for 25GbE, ensuring interoperability and seamless integration into existing network infrastructures requiring enhanced bandwidth and low latency. Its primary function is to convert electrical signals into optical signals for transmission and vice-versa, enabling efficient communication between network devices. This SFP28 transceiver is predominantly deployed in environments demanding increased bandwidth and reduced latency, such as hyperscale data centers, cloud computing facilities, and large enterprise networks. It is commonly installed in 25GbE-capable network switches, servers, and network interface cards (NICs) from HP and other compatible vendors. The HP 845398-B21 addresses the growing need for higher-density server connectivity and faster interconnects for storage area networks (SANs) and network-attached storage (NAS) systems. It serves as a critical component for telecom operators and internet service providers upgrading their backbone and access networks, providing a cost-effective upgrade path from 10GbE SFP+ deployments to meet escalating data traffic demands. Its robust design ensures reliable performance in demanding B2B operational environments.
