Cisco SFP-10G-LR-I Compatible 10GBASE-LR SFP+ 1310nm 10km Industrial DOM Duplex LC SMF Optical Transceiver Module

Overview

Ensure reliable connectivity in the most demanding environments with the SFP-10G-LR-I Compatible transceiver. While standard optics are designed for climate-controlled data centers, this Industrial Temperature (Ind Temp) module is engineered to perform flawlessly in extreme heat and freezing cold. It adheres to the 10GBASE-LR standard, delivering 10 Gigabit Ethernet speeds up to **10 kilometers** over Single-Mode Fiber (SMF) using a 1310nm wavelength.

The SFP-10G-LR-I is the ideal choice for outdoor cabinets, factory floors, and unconditioned industrial spaces where temperatures can fluctuate between -40°C and +85°C.

Key Features

• Industrial Grade Reliability: Operational temperature range of -40°C to +85°C (-40°F to 185°F).
• Standard 10G Reach: Supports link lengths up to 10km on standard Single-Mode Fiber (G.652).
• Wavelength: 1310nm DFB Laser transmitter.
• Robust Components: Hardened internal components (lasers, photodetectors, and ICs) designed to resist thermal stress.
• Connector: Duplex LC interface.
• DOM/DDM Support: Critical for industrial monitoring, allowing real-time checks of temperature, voltage, and optical power.

Applications

The SFP-10G-LR-I is essential for networks that extend beyond the office:

• Outdoor Telecommunications: Cell tower base stations and remote radio heads (RRH) where equipment is exposed to the elements.
• Industrial Automation: Factory floors with high ambient temperatures or heavy machinery.
• Traffic & Surveillance: Roadside control cabinets and traffic camera aggregation points.
• Energy & Utilities: Remote substations, oil & gas pipelines, and wind farm connectivity.
• Military & Aerospace: Field-deployable networks requiring ruggedized hardware.

Specifications

Cross-Platform Compatibility

Our 10GBASE-LR-I modules are manufactured to meet specific industrial MSA standards, ensuring compatibility with hardened switches and routers from major brands, including:

Advantages

Using a commercial-grade module in an industrial environment is a common cause of network failure. The optical drift caused by extreme heat can lead to packet loss or link failure. The SFP-10G-LR-I utilizes thermally stable lasers and industrial-rated soldering and packaging to ensure that your data keeps flowing, regardless of whether it is freezing winter or blistering summer.

FAQ (Technical & Product Questions)

1. Can I use this module in a standard (non-industrial) switch?

Yes, absolutely. An industrial temperature module exceeds the specifications of a commercial one. It will function perfectly in a standard 25°C office environment. It is simply “over-engineered” for that purpose.

2. What happens if I use a commercial module outdoors instead of this one?

Commercial modules are rated for 0°C to 70°C. In freezing conditions, the laser may fail to start. In extreme heat (above 70°C), the laser wavelength can drift, causing high bit error rates, and the lifespan of the module will be significantly reduced.

3. Does this module consume more power?

Industrial modules may have slightly higher power consumption requirements at the extremes of their temperature range to maintain laser stability, but they generally adhere to the standard SFP+ power classes (typically < 1.5W).

4. Is the 10km distance affected by temperature?

No. The internal circuitry compensates for temperature changes to ensure the laser output power and receiver sensitivity remain within the 10GBASE-LR specifications across the full -40°C to +85°C range.

5. What fiber cable should I use?

You should use standard Single-Mode Fiber (SMF), typically OS1 or OS2 (9/125 micron). For outdoor deployments, ensure your fiber patch cables are also rated for the appropriate environmental conditions.
