About This Part
The HP 845968-B21 is a high-performance QSFP28 (Quad Small Form-Factor Pluggable 28) optical transceiver, specifically designed for 100 Gigabit Ethernet (100GbE) applications. This module belongs to the eSR4 product family, indicating its enhanced short-reach capabilities. Operating at a nominal wavelength of 850nm, it utilizes an MPO (Multi-fiber Push On) connector for its optical interface, facilitating parallel optical transmission. The transceiver supports a data rate of 100Gbps, achieved by aggregating four independent 25Gbps channels (4x25G). Its primary function is to convert electrical signals into optical signals and vice-versa, enabling high-bandwidth data transmission over multi-mode fiber. With a maximum reach of 300 meters over OM4 multi-mode fiber, the HP 845968-B21 is optimized for intra-data center links, high-performance computing interconnects, and enterprise network aggregation points where reliable, high-speed, and cost-effective short-distance optical connectivity is paramount. Its compact QSFP28 form factor ensures high port density in network switches and routers. The HP 845968-B21 transceiver is typically deployed in core and aggregation layers of data centers, enterprise networks, and campus environments. It is installed in compatible QSFP28 ports of network switches, routers, and host bus adapters from various manufacturers, including HP ProLiant servers and Aruba networking equipment that support 100GbE connectivity. This module is critical for establishing high-speed interconnects between servers, storage arrays, and network infrastructure, addressing the escalating demand for bandwidth driven by virtualization, cloud computing, and big data analytics. It effectively solves the challenge of high-density, short-to-medium distance 100GbE links, providing a robust upgrade path from previous generation 10GbE or 40GbE infrastructures. Industries such as telecommunications, financial services, research institutions, and large enterprises leverage this transceiver to build scalable and high-performance network backbones, ensuring low latency and high throughput for critical applications. It often replaces multiple lower-speed transceivers or older, less efficient 100G solutions, streamlining cabling and reducing operational complexity.
