The Eaton Tripp Lite Series Cisco-Compatible SFP-25G-SR-S SFP28 Transceiver is a high-performance, plug-and-play solution designed to upgrade data-center and enterprise networks to 25G speeds with minimal disruption. Capable of delivering reliable 25GBASE-SR connectivity over multimode fiber, this module fits standard SFP28 ports and features a duplex LC connector, 850 nm VCSEL optics, and Cisco-compatible interoperability. Built to support modern workloads—from virtualization to cloud-enabled workloads—the transceiver helps you maximize your existing fiber infrastructure while enabling faster uplinks, reduced latency, and improved application performance across servers, storage, and network switches. With digital diagnostics monitoring (DDM/DOM), a compact hot-swappable form factor, and a robust, enterprise-grade build, it’s an ideal choice for organizations seeking scalable, energy-efficient upgrades without a costly rip-and-replace expansion.

• High-speed 25GBASE-SR performance over multimode fiber: This SFP28 transceiver delivers 25 Gbps data rates for server-to-switch uplinks, storage interconnects, and top-of-rack deployments, enabling smoother data transfer, faster backups, and improved multi-tenant performance in virtualized environments. The 850 nm VCSEL transmitter and sensitive receiver optics are optimized for short-reach links, making it ideal for data centers and campus networks that rely on fast, low-latency connectivity over existing fiber cabling.
• Cisco-compatible SFP28 module with simple, plug-and-play integration: Engineered for seamless interoperability with Cisco switches, routers, and other compatible devices, this transceiver minimizes compatibility concerns during upgrades. It adheres to the SFP28 standard and supports common management operations, allowing administrators to deploy the module across multi-vendor environments without extensive reconfiguration or vendor lock-in.
• Duplex LC connector, 850 nm MMF optics, up to 100 meters: The module uses a standard duplex LC optical interface and multimode fiber compatible with OM3/OM4 cabling, enabling reliable short-reach links within racks, between racks, or across data-center floors. The 100-meter maximum distance supports typical top-of-rack and adjacent-switch interconnects, helping you optimize rack density while preserving existing fiber infrastructure.
• Digital diagnostics monitoring (DDM/DOM) and reliable operation: Built with modern monitoring capabilities, the transceiver provides real-time insight into critical operating parameters such as optical power, supply voltage, temperature, and TX/RX metrics. This visibility helps administrators proactively manage health, anticipate faults, and accelerate troubleshooting, resulting in higher uplink availability and reduced mean time to repair.
• Compact, hot-swappable design for flexible upgrades and maintenance: The SFP28 form factor is designed for easy installation and removal without powering down network equipment in many cases, reducing downtime during upgrades or replacements. Its rugged construction and standardized footprint ensure compatibility across a wide range of chassis, switches, and fiber-centric architectures, making it a practical component for data-center modernization campaigns.

How to install Eaton Tripp Lite SFP-25G-SR-S Transceiver

Installing this transceiver is straightforward and designed to minimize downtime during upgrades. Follow these best-practice steps to ensure a successful deployment and stable operation in your network environment:

• Power down the affected port or device only if your hardware policy requires it; in many configurations, the hot-swappable design permits replacement without a full shutdown. Ensure you follow your organization’s maintenance window guidelines.
• Inspect the SFP28 slot for any debris or dust. A clean slot helps prevent surface contamination that could impede electrical contact or optical alignment. If needed, gently remove dust with a clean, lint-free cloth or compressed air suitable for electronics.
• Align the transceiver with the slot and insert it firmly until it seats with a click. Avoid excessive force to prevent damage to the connector or the host device. Confirm that the module is fully engaged and locked in place according to your equipment’s guidelines.
• Connect the multimode fiber cable to the duplex LC connector, ensuring correct polarity (Tx to Rx). Use certified MMF cables (OM3/OM4 recommended) and verify the cable’s MPO/LC transitions if your topology requires adapters.
• Power on the device (or the port, if it was powered down) and verify link status through the device’s management interface. Run a basic connectivity test, such as ping or a small data transfer test, to confirm the uplink is operational and stable at 25 Gbps.

Frequently asked questions

• Q: Is this transceiver Cisco-compatible?
• A: Yes. It is marketed as Cisco-Compatible SFP-25G-SR-S and is designed to work with Cisco switches and routers that support SFP28 25GBASE-SR transceivers, providing predictable interoperability in mixed-vendor environments.
• Q: What type of fiber and connector does it use?
• A: It uses multimode fiber with a duplex LC connector and operates at 850 nm for 25GBASE-SR connections, making it well-suited for short-reach, high-bandwidth links within data centers.
• Q: What is the maximum transmission distance?
• A: Up to 100 meters when deployed on appropriate multimode fiber such as OM3 or OM4 cabling, which covers most data-center uplinks and top-of-rack configurations.
• Q: Does it support monitoring and diagnostics?
• A: Yes. It includes Digital Diagnostics Monitoring (DDM/DOM), enabling real-time visibility into optical power, temperature, voltage, and other critical parameters.
• Q: How do I know if my device supports SFP28 25GBASE-SR?
• A: Check your switch or router’s hardware specifications for SFP28 (25G) compatibility and confirm vendor interoperability guidelines for the exact model and firmware version you are using.
• Q: Can I reuse existing fiber infrastructure when upgrading to 25G?
• A: In most cases, yes. Upgrading to a 25GBASE-SR transceiver on MMF with LC connectors typically leverages your current OM3/OM4 cabling, reducing the need for new fiber runs and lowering total cost of ownership while delivering substantial performance gains.
