Cisco SFP-10/25G-LR-I Compatible SFP28 10/25GBASE-LR Dual-rate 1310nm 10km DOM Duplex LC/UPC SMF Optical Transceiver Module (Industrial)

Overview

The SFP-10/25G-LR-I is a versatile, high-performance SFP28 transceiver engineered for reliability in harsh industrial environments. Its standout feature is its dual-rate capability, allowing it to operate seamlessly in both 25GBASE-LR and 10GBASE-LR networks. This makes it an exceptionally flexible solution for companies planning a phased upgrade from 10G to 25G Ethernet, protecting their investment and simplifying inventory management. Designed for an extended reach of up to 10 kilometers over single-mode fiber, it is perfect for campus backbones, service provider access networks, and industrial interconnects.

This module’s industrial-grade components ensure stable operation across an extreme temperature range of -40°C to 85°C. Built to be fully compliant with SFP28 MSA standards, it offers plug-and-play interoperability with a wide range of industrial switches, routers, and transport equipment. It utilizes a reliable 1310nm DFB laser and features a duplex LC connector, providing a robust physical connection. Digital Optical Monitoring (DOM) is supported, giving network administrators real-time visibility into critical performance metrics.

Specifications

Advantages

The SFP-10/25G-LR-I transceiver offers a clear strategic advantage. It provides a seamless and cost-effective upgrade path from 10G to 25G, allowing organizations to enhance their network capacity without a disruptive and expensive overhaul of existing fiber infrastructure. Its industrial rating guarantees performance and longevity in challenging physical environments where standard commercial-grade optics would fail. By consolidating two data rates into a single module, it simplifies network management, reduces spare parts inventory, and lowers the total cost of ownership.

FAQ (Technical & Product Questions)

1. What does dual-rate 10/25G mean?

Dual-rate means the transceiver can operate at two different speeds. This module can be configured to run at either 10 Gbps (for 10GBASE-LR applications) or 25 Gbps (for 25GBASE-LR applications), providing significant network design flexibility.

2. What does the `-I` in the part number signify?

The `-I` signifies that this is an Industrial-grade module. It is built with components that can withstand a wider operating temperature range, from -40°C to 85°C, making it suitable for outdoor or unconditioned environments.

3. Can I use this SFP28 module in an SFP+ port?

Yes. When this SFP28 module is plugged into an SFP+ port on a host device, it will auto-negotiate and operate at the 10 Gbps data rate, functioning as a 10GBASE-LR module.

4. Why would I choose a dual-rate module instead of two separate modules?

A dual-rate module is ideal for network upgrades. You can deploy it in your current 10G network and then re-configure it for 25G when your switches are upgraded. This saves money, reduces downtime, and simplifies inventory to a single part number.

5. What is the main application for an industrial temperature transceiver?

They are used in networking equipment located in places without climate control, such as outdoor enclosures, factory floors, substations, and along transportation routes, where temperatures can fall below freezing or rise to extreme highs.

6. What fiber optic cable should be used with this module?

To achieve the maximum 10km distance, you must use an OS1 or OS2 type Single-Mode Fiber (SMF) patch cable that is terminated with Duplex LC/UPC connectors.

7. Is this module MSA compliant?

Yes. It is manufactured according to the SFP28 Multi-Source Agreement (MSA). This ensures it follows standardized electrical and mechanical specifications, making it interoperable with equipment from various manufacturers that also adhere to the MSA standards.
