Aerohive

Introducing the Aerohive 25GBase-SR SFP28 transceiver — the smart, high-performance solution for building scalable optical networks in data centers, campuses, and edge deployments. This short-range, multi-mode fiber transceiver is engineered to deliver reliable 25 Gigabit Ethernet connectivity over existing MMF infrastructure, enabling rapid upgrades from 10G links without the cost and complexity of new fiber installs. The Aerohive SFP28 module is designed for ease of integration with Aerohive switches and routers, and it is also compatible with a wide range of SFP28-capable devices that support 25GBASE-SR, providing a flexible path to higher bandwidth and lower latency. Whether you are optimizing server-to-switch uplinks, enhancing storage networks, or expanding your hyper-converged infrastructure, this transceiver offers a compact, hot-swappable footprint that fits seamlessly into your data center topology.

• High-speed 25GBASE-SR over multi-mode fiber: This module uses an 850 nm VCSEL transmitter to deliver a robust 25 Gbps data rate over short-range MMF. It is optimized for 25G Ethernet links on multi-mode fiber, enabling fast, efficient uplinks and server connections without rewiring or replacing fiber infrastructure.
• Plug-and-play, hot-swappable SFP28 form factor: The Aerohive transceiver is designed for easy upgrades and maintenance. Install in compatible SFP28 slots without powering down equipment (where hot-swapping is supported by the host), minimizing downtime and keeping your network online while you scale.
• Broad compatibility and ecosystem flexibility: Built to integrate with Aerohive switches and routers, this module also aligns with other SFP28-port devices that support 25GBASE-SR. The result is a flexible upgrade path that preserves your current topology while enabling seamless capacity expansion and improved data throughput across workloads such as virtualization, analytics, and backups.
• Reliability, standards compliance, and durable design: The transceiver adheres to industry-standard SFP28 specifications, with RoHS-compliant materials and robust, lock-in fiber connections. Its mechanical and electrical interfaces are engineered to withstand routine use in data center environments, delivering consistent optical performance and long-term reliability.
• Cost-efficient performance with energy-conscious operation: By delivering high bandwidth per port over existing MMF, this 25GBASE-SR module reduces total cost of ownership while helping to lower power consumption per transferred bit. It enables more efficient utilization of switching fabric and network resources, supporting streamlined deployment and maintenance cycles for growing networks.

How to install Aerohive 25GBase-SR SFP28

• Verify compatibility: Ensure your network device supports SFP28 25GBASE-SR modules and that hot-swapping is supported by the chassis or switch. Confirm fiber availability and that the fiber path is clean and properly terminated with LC connectors.
• Prepare the fiber: Use a clean MMF fiber patch cord with LC-LC connectors appropriate for OM3/OM4 types. Inspect connectors for dust and damage, and clean with proper fiber-cleaning tools before insertion.
• Handle with care: Hold the transceiver by its body and avoid touching the connector end faces. Align the module with the switch/router slot and slide it straight in until it seats firmly. You should feel a gentle click when the module is securely seated.
• Connect the fiber: Attach the MMF patch cable to the LC duplex connectors on the transceiver and route the fiber to the corresponding port, ensuring minimal bend radius and secure fiber management to prevent signal loss.
• Verify operation: Power on the device (or perform hot-swapping if supported). Access the management interface to confirm link status, optical power levels, and the negotiated 25 Gbps speed. Run a basic throughput test to validate performance and ensure no error counters are present.
