Now the 10G SFP+ module is popular in the market and more and more customers began to use them. They are not too expensive. There are many different types of 10G SFP+ transceivers such as SFP-10G-SR, SFP-10G-LR, SFP-10G-LRM, SFP-10G-ER, and SFP-10G-ZR. What are their similarity and differences? Many IT professionals may be confused. We would like to make a comparison for them.
We can learn the similarity from the above specs comparison, the similarity is all the five SFP+ types support same data rate, same fiber connector, and same operating temperature. The difference is the wavelength, distance, and compliant standard.
SFP-10G-SR
The SFP-10G-SR is a 10GBase-SR SFP+ module that offers customers a range of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closets and service provider transport applications. The module has many features and benefits, including the industry’s smallest form factor, the highest density of each chassis. These modules are also hot-swappable and can be easily switched. These modules also feature digital optical monitoring (DOM) to monitor signal strength, SFP temperature, and transceiver voltage. The SFP-10G-SR module supports links up to 300 meters in multimode OM3 fiber.SFP-10G-LR
The SFP-10G-LR is a 10GBase-LR SFP+ module that offers customers with a variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closets and service provider transport applications. The SFP-10G-LR module supports 10 km of link length on standard single-mode fiber (SMF, G.652).SFP-10G-LRM
The SFP-10G-LRM is a 10GBASE-LRM Module supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met over FDDI-grade, OM1 and OM2 fibers, the transmitter should be coupled through a mode conditioning patch cord. No mode conditioning patch cord is required for applications over OM3 or OM4.SFP-10G-ER
The SFP-10G-ER is a 10GBase-ER SFP+ module that offers customers with a variety of 10 Gigabit Ethernet connectivity options for data center, enterprise wiring closets and service provider transport applications. The SFP-10G-ER module supports 40 km of link length on standard single-mode fiber (SMF, G.652).SFP-10G-ZR
The SFP-10G-ZR is a 10GBase-ZR/ZW SFP+ module with LC duplex interface operates with single-mode optical fiber. The SFP-10G-ZR hot-swappable transceiver module with LC/PC connectors can be used for data networking/optical network applications. It supports 80 km of link length on standard single-mode fiber (SMF, G.652).Comparison: SFP-10G-SR vs SFP-10G-LR vs SFP-10G-LRM vs SFP-10G-ER vs SFP-10G- ZR, What is the similarity and difference?
Now let us make a comparison of the similarity and difference, it will help you choose right 10G SFP+ module depends on your application.| Models / Specs | Data Rate | Wavelength | Fiber mode | Distance | Connector | Standard | Operating Temperature |
| SFP-10G-SR | 10G | 850nm | Multimode | 300 m | Duplex LC | 10GBASE-SR | Commercial 0~70°C |
| SFP-10G-LR | 10G | 1310nm | Single mode | 10 km | Duplex LC | 10GBASE-LR | Commercial 0~70°C |
| SFP-10G-LRM | 10G | 1310nm | Multimode | 220 m | Duplex LC | 10GBASE-LRM | Commercial 0~70°C |
| SFP-10G-ER | 10G | 1550nm | Single mode | 40 km | Duplex LC | 10GBASE-ER | Commercial 0~70°C |
| SFP-10G-ZR | 10G | 1550nm | Single mode | 70km ~80 km | Duplex LC | 10GBASE-ZR | Commercial 0~70°C |
Conclusion
After the comparison, have you know the difference between SFP-10G-SR vs SFP-10G-LR vs SFP-10G-LRM vs SFP-10G-ER vs SFP-10G- ZR? Which one should you choose?

Have a question regarding SFP-10G-LR and SFP-10G-LRM. Is it possible to use an SFP-10G-LRM on a single mode fiber connection on both ends? If it is possible, what are the down sides to doing so?
Good post but I was wanting to know if you could write a litte more on this subject?
I’d be very grateful if you could elaborate a little bit
more. Thanks!
I’ll right away clutch your rss as I can not in finding your email subscription hyperlink or newsletter service.
Do you have any? Kindly permit me understand in order that I may subscribe.
Thanks.
An impressive share! I’ve just forwarded this onto a coworker who has been conducting
a little homework on this. And he in fact bought me breakfast simply because I found it for him…
lol. So allow me to reword this…. Thanks for the meal!!
But yeah, thanks for spending some time to talk about this issue here on your blog.
My brother suggested I would possibly like this blog. He was entirely right.
This post truly made my day. You cann’t consider just how a
lot time I had spent for this information! Thanks!
