Compact Form Factor

The SFP28 form factor used in the HPE 849442-001 is a continuation of the SFP+ design philosophy but enhanced to support significantly higher data rates of 25 Gbps per lane. Its plug-in module architecture ensures hot-swappable capability, allowing network administrators to install or replace the module without shutting down critical network equipment. This reduces downtime and supports continuous service availability in enterprise environments.

Integrated Signal Conditioning

Signal conditioning within the module ensures minimal jitter, reduced bit error rates, and optimized transmission performance even in dense networking environments. Advanced equalization techniques are applied internally to maintain signal clarity across the maximum supported distance of 100 meters.

25GBASE-SR Standard Transceiver

The HPE 849442-001 operates based on the 25GBASE-SR standard, which defines short-range optical communication over multimode fiber using 850nm wavelength VCSEL (Vertical-Cavity Surface-Emitting Laser) technology. This standard is widely deployed in data center environments where high-speed connectivity between switches, servers, and storage systems is required over relatively short distances.

Hot-Pluggable Capability

This transceiver module supports hot-plug functionality, enabling installation or removal without powering down network devices. This ensures minimal downtime and improved operational continuity in mission-critical systems.

Ultra-Fast 25GbE Connectivity

Designed for next-generation networking demands, the HPE 849442-001 provides 25GbE bandwidth, enabling seamless handling of large-scale data traffic, virtualization workloads, and high-performance computing environments.

High-Speed Ethernet Protocol Efficiency

Supporting 25 Gigabit Ethernet data link protocol, this module enables significantly improved throughput compared to legacy 10GbE systems while maintaining backward compatibility in structured network upgrades. The transition to 25GbE allows organizations to optimize port utilization, reduce the number of required physical links, and improve overall network efficiency.

Dual LC Connector Architecture

The module utilizes LC duplex connectors, which are industry-standard interfaces for high-density optical networking. These connectors provide a compact footprint while maintaining strong optical alignment and minimal insertion loss. The duplex configuration allows separate fibers for transmit and receive paths, ensuring stable full duplex communication.

Multimode Fiber Compatibility

Designed specifically for multimode fiber cabling, the HPE 849442-001 is optimized for cost-effective short-range deployments. Multimode fiber enables efficient transmission of high-bandwidth signals within structured cabling systems commonly found in enterprise data centers, campus networks, and server rooms.

25 Gbps Data Transfer Rate Optimization

With a native data transfer rate of 25 Gbps, the HPE 849442-001 significantly enhances network throughput, enabling faster data replication, reduced backup windows, and improved application responsiveness. This level of performance is essential for modern virtualization platforms and cloud-native architectures.

Distance Range and Transmission Limitations

The HPE 849442-001 supports transmission distances up to 100 meters (328 feet), making it ideal for intra-rack and inter-rack connectivity within data centers. This distance range aligns with typical structured cabling layouts in enterprise environments where devices are located within the same facility.

Compatibility with HPE Switch Ecosystems

The HPE 849442-001 is engineered for seamless integration with HPE networking hardware, including high-performance switches and modular chassis systems. This ensures optimized firmware compatibility, enhanced diagnostic capabilities, and improved interoperability across enterprise networks.

High Availability Networking Support

In high availability architectures, redundancy is essential. This transceiver module supports redundant network paths, enabling failover configurations that maintain uninterrupted service in case of link or hardware failure.

Transition from 10GbE to 25GbE Standards

The shift from 10 Gigabit Ethernet to 25 Gigabit Ethernet represents a significant technological advancement in networking efficiency. The HPE 849442-001 plays a key role in enabling this transition by providing a cost-effective and scalable upgrade path.
