Overview
This transceiver is a high-performance, industrial-grade SFP+ module engineered for 100% compatibility with the Cisco SFP-10GLRL-31-I. It is specifically designed to provide reliable 10 Gigabit Ethernet connectivity in harsh environmental conditions, with a ruggedized construction that supports an operating temperature range of -40°C to 85°C (-40°F to 185°F).
Following the 10GBASE-LRL standard, this module uses a dependable 1310nm DFB laser to establish stable data links up to 2 kilometers over standard Single-Mode Fiber (SMF). Its hardened design makes it the perfect solution for deploying high-speed networks in outdoor enclosures, factory floors, transportation systems, and other unconditioned environments where commercial-grade components would fail.

Advantages
The key advantage of this industrial-grade transceiver is its reliability under extreme conditions. It eliminates the risk of network failure due to temperature, providing consistent performance where commercial parts cannot. By choosing this compatible module, you achieve the same level of rugged performance as OEM hardware but at a significantly lower cost, enabling robust and budget-conscious network deployments in any environment.
FAQ (Technical & Product Questions)
1. What does “Industrial” mean for a transceiver?
An “Industrial” or industrial-grade transceiver is built with components that are rated to operate reliably over a much wider temperature range, typically -40°C to 85°C (-40°F to 185°F). This is in contrast to commercial-grade modules, which are usually rated for 0°C to 70°C (32°F to 158°F).
2. What is the difference between 10GBASE-LRL and 10GBASE-LR?
Both use 1310nm wavelength over single-mode fiber. The main difference is the intended reach and power. 10GBASE-LR (Long Reach) is standardized for 10km. 10GBASE-LRL (Long Reach Lite) is a variation intended for shorter distances, in this case, 2km. It typically uses lower-power optics compared to a full 10km LR module.
3. Can I use this industrial module in a commercial-grade switch?
Yes, absolutely. An industrial module will function perfectly in a controlled environment (like a data center) where a commercial switch operates. You can use an industrial module anywhere you would use a commercial one, but not vice-versa.
4. Will this 2km module work over a shorter distance, like 100 meters?
Yes, this module will work perfectly over shorter link lengths. Its receiver is designed to handle the higher signal power associated with short distances without issue. No optical attenuators are typically needed for links of 1 meter or more.
5. What kind of fiber cable is required for this module?
This module requires a standard single-mode fiber (SMF) patch cable (OS1 or OS2, typically with a yellow jacket) terminated with Duplex LC/UPC connectors.
6. Will using this compatible SFP+ void my switch’s warranty?
No. It is a common misconception that using third-party transceivers will void your equipment warranty. The Magnuson-Moss Warranty Act and similar laws protect consumers from this practice. Our modules are built to MSA standards to ensure they will not damage your equipment.
7. Is this module compatible with multi-mode fiber (MMF)?
No. The 1310nm laser optics are specifically designed for transmission over Single-Mode Fiber (SMF). Using it with multi-mode fiber will result in very poor performance or a complete failure to establish a link.
