Cisco SFP-10G-SR-I Compatible 10GBASE-SR SFP+ 850nm 300m Duplex LC MMF DOM Optical Transceiver Module (Industrial)

Overview

Ensure reliable connectivity in your most demanding environments with the SFP-10G-SR-I Compatible transceiver. This module is the Industrial Temperature (Ind-Temp) variant of the standard 10GBASE-SR SFP+, specifically hardened to withstand extreme thermal conditions.

While standard commercial modules fail outside of climate-controlled data centers, the SFP-10G-SR-I is engineered to operate flawlessly in temperatures ranging from -40°C to +85°C. It transmits 10 Gigabit Ethernet data at 850nm over Multimode Fiber (MMF), reaching distances of up to 300 meters on OM3 cable (or 400m on OM4). It is the perfect solution for outdoor enclosures, factory floors, and unconditioned remote sites.

Key Features

• Industrial Temperature Range: Certified for operation from -40°C to +85°C (-40°F to 185°F).
• High Speed: Supports 10.3125 Gbps data rates.
• Short Range Reach: Up to 300m on OM3 MMF / 400m on OM4 MMF.
• Wavelength: 850nm VCSEL Laser.
• Connector: Duplex LC interface.
• Durability: Hardened components for resistance to thermal shock and vibration.
• Compatibility: Fully compliant with SFP+ MSA and IEEE 802.3ae 10GBASE-SR standards.

Applications

The SFP-10G-SR-I is essential for networks deployed outside of standard air-conditioned server rooms:

• Outdoor Telecom Cabinets: Connecting street-level aggregation switches or cell tower base stations.
• Industrial Automation: Factory floors with high heat generation or unheated warehouses in freezing climates.
• Oil & Gas / Mining: Remote monitoring stations exposed to extreme weather elements.
• Traffic & Utility Networks: Intelligent traffic systems and utility substations.

Specifications

Cross-Platform Compatibility

Our Industrial 10GBASE-SR modules are coded to be fully compatible with the “ruggedized” or “industrial” equipment lines of major manufacturers. Common equivalents include:

Advantages

The primary advantage of the SFP-10G-SR-I is reliability in hostile environments. Using a standard “Commercial Temp” (C-Temp) module in an outdoor cabinet can lead to link flaps, data errors, or total component failure when temperatures drop below freezing or soar during summer. This Industrial module guarantees uptime regardless of the weather, protecting your critical infrastructure links.

FAQ (Technical & Product Questions)

1. Can I use this Industrial module in a regular switch?

Yes, absolutely. You can use an Industrial Temperature (I-Temp) module in a standard commercial switch without any issues. In fact, because I-Temp modules are built with higher-grade components, they often run cooler and last longer than standard modules in normal environments.

2. What cable do I need?

You need a standard Multimode (OM3 or OM4) fiber patch cable with Duplex LC connectors. Aqua-colored cables are the industry standard for 10G multimode.

3. What is the difference between SR and SR-I?

The optical performance (speed and distance) is identical. The difference is the operating temperature range. “SR” is rated for 0°C to 70°C, while “SR-I” is rated for -40°C to 85°C. The SR-I uses more robust components to handle these extremes.

4. Is this module “Ruggedized”?

Yes, in networking terms, “Industrial Temperature” and “Ruggedized” often refer to the same capability—the ability to withstand harsh thermal environments and often higher levels of vibration.

5. Will this work with Cisco Industrial Ethernet (IE) switches?

Yes, this module is specifically designed for switches like the Cisco IE series (IE-4000, IE-5000) that require I-Temp optics to maintain their warranty and performance ratings.
