SFP28 25Gb Optical Transceiver HP Enterprise 849442-001, SR 100m

HP Enterprise SFP28 25Gb SR optical transceiver provides short-range multimode fiber connectivity up to 100 meters. Designed for 25 Gigabit Ethernet ports, this SFP28 module fits standard SFP28 slots and enables high-speed intra-rack and data-center links. The transceiver is intended for reliable short-distance 25GbE links between servers, switches and storage equipment where multimode fiber infrastructure is already deployed.

Advantages

This optical transceiver delivers 25 Gigabit Ethernet performance over multimode fiber for short-range links up to 100 m. Its SFP28 form factor ensures compatibility with equipment that supports SFP28 ports, enabling higher port density and straightforward upgrade paths from 10GbE to 25GbE. The module offers low power consumption and predictable latency suitable for data center top-of-rack and spine-leaf architectures.

Suitable for

• Short-range server-to-switch connections in data centers
• Top-of-rack and leaf-spine network links within racks
• High-speed storage area network interconnects over multimode fiber
• Environments requiring compact SFP28 modules for port density

Key specifications

• Data rate: 25 Gigabit Ethernet
• Optical interface: SR (short reach) multimode fiber
• Maximum reach: up to 100 meters on multimode fiber
• Connector type: duplex LC
• Form factor: SFP28
• Typical power consumption: low (suitable for dense deployments)
• Transmission: full-duplex

How to use

Install the SFP28 transceiver into an available SFP28 slot on the switch, server NIC or storage adapter until it clicks into place. Connect duplex LC multimode fiber patch cords between transceivers on each end, ensuring correct fiber type and polishing grade for SR links. After insertion, verify link status and speed through the host device management interface and confirm the port is configured for 25GbE operation. Follow the equipment vendor’s firmware and compatibility guidelines to ensure proper recognition and performance.

Usage recommendations

Use OM3 or OM4 multimode fiber for reliable 100 m links and maintain clean LC connectors to prevent signal loss. Verify transceiver compatibility with the specific switch or NIC model and apply appropriate firmware or driver updates as recommended by the equipment vendor.
