There are many versions of SFP-10G SR optical modules, including SFP-10G-SR, SFP-10G-SR-S, and SFP-10G-SR-X, which can be applied to network switches and other network equipment. Generally speaking, SFP-10G SR optical modules are used in very short distances, and many engineers do not know the detailed differences between them, This article will introduce these three products in detail and how to choose a suitable SFP 10G SR optical module.

What is an SFP 10G SR Optical Module?

10G SFP SR module is a hot plug input and output device, which supports a maximum transmission distance of 300m matched with OM3 multimode fiber. 10G SFP SR optical module can support 10 Gigabit Ethernet port to build 10G Optical fiber network transmission. At the same time, SFP-10G-SR optical module also supports the alternative compatibility of 10Gbase-SR SFP+, and many third-party suppliers provide the same function and performance.

What is an SFP 10G SR-S Optical Module?

SFP-10G-SR-S is different versions of SFP-10G-SR. their main difference is that they have different functions. According to Cisco’s report, the S-class optical device series is mainly a cheaper choice for enterprises and data centers working in 10G and 40G application design. The S-class products are mainly used for applications that do not need control temperature and stability, such as rugged / Industrial (RGD),  Optics plugged on platforms that require extended operating temperature range (EXT), TAA compliance.

As we mentioned above, the price of 10G-SFP-SR-S will be cheaper, because SFP-10G-SR-S reduces some functions that are not necessary, it can be used as a replacement for 10GBASE-SR modules, and it can also be used for compatible Cisco switches, which can save some cost to the enterprise or data center

What is an SFP 10G SR-X Optical Module?

SFP-10G-SR-X is the part number of the 10GBASE-SR SFP + optical module. 10GBASE-SR-X SFP+ module can support multi-rate data transmission, including 10GBASE-SR, 10GBASE-SW, and OTU2/OTU2e. Using the SFP-SR-X module can expand the working range and temperature of the Ethernet switch. The main difference of the 10GBASE-SR-X and the mentioned above two optical modules is that the SFP-SR-X supports OTU2/OTU2e.

Like SFP-10G-SR-S, it can be used as a replacement for 10GBASE-SR modules, and it can also be used for compatible Cisco switches.

Through the comparison of this article, I believe you already know the difference between SFP-10G-SR, SFP-10G-SR-S, and SFP-10G-SR-X. they all belong to 10Gbase-SR SFP+ optical modules, but their working temperatures are different and their working data transmission rates are different, but in general, they all have the same functions in terms of price, SFP-10G-SR and SFP-10G-SR-S are cheaper than 10G-SR-X. through these comparisons, I believe you know how to select a suitable optical module. QSFPTEK provides the most cost-effective and high-quality third-party 10GBASE-SR SFP+ optical module. If you have any questions, please contact us via sales@QSFPTEK.com
