What is an SFP+ module?
The SFP+ module is also called the SFP+ transceiver, SFP+ optical module, SFP+ optics, or SFP+ fiber transceiver. Although with several different names, they are the same product. However, most vendors referred to it as an SFP+ module and transceiver. When you search it on Google, you will find plenty of SFP+ suppliers, vendors, or shops.
Compared with the SFP module, the SFP+ module supports a higher speed of 8GFC, 10Gbps, and 16GFC. Furthermore, it also features a required built-in DDM/DOM (digital optical monitor) per SFF-8472. Whilersrose, the SFP module has no requirement for this function.
A typical SFP+ module comprises a cage, PCBA, chip, and optical TOSA+ROSA (sometimes BOSA for BiDi transceiver). See the below image.

To help understand the SFP+ better, we briefly introduce the basic SFP+ MSA (multi-source agreement). SFF-8431 and SFF-8432, launched by SFF Committee, define the electrical characteristics and mechanical specifications of the SFP+ module and host. Click here to learn more about the MSA.
FAQs About 10G SFP+ Transceivers
Q: SFP vs. SFP+. What is the difference?
A: The critical difference is the data transmission speed. SFP supports the typical rate of 155M, 1.25G, and 2.5G, whereas the SFP+ support 10G and 8G/16GFC.
Q: What is the maximum transmission distance SFP+ module?
A: It depends on the SFP+ speed. Take the 10G SFP+ as an example; most vendors provide an 80km version, but Optcore may provide an ultra-long distance of 100km over single mode fiber.
Q: Can I connect an SFP+ with an XFP module?
A: The answer is yes. But make sure that they have the same transmission speed and wavelength. Or else they will fail to establish a link.
Q: Can I receive a refund or return the product?
A：If you are unsatisfied with the product, you can either return it or request a refund from us. However, please remember that refunds will only be issued if the product is returned within 30 days of being received.
Q: What is the warranty for your 10G SFP+ transceivers?
A：All of our 10G SFP+ transceivers come with a 3-year warranty.
Q: What type of fiber cable should I use with Walsun 10G SFP+ transceivers?
A：It depends on the transceiver. For 10GBASE-SR & 10GBASE-LRM transceiver, you may use OM2 or OM3 fiber; OM3 fiber is a better choice because it has a more extended reach than OM2. For 10GBASE-LR/ER/ZR SFP+ transceiver, you should use a single mode fiber cable.
Q: What’s the weight of this SFP+ transceiver？
A：The net weight for this SFP+ is around 25 grams, and the shipping weight is approximately 30 grams.
Q: How to check the DDM information?
A：DDM also refers to DOM, allowing users to access diagnostic monitoring data for transceivers that enable Diagnostic Optical Monitoring (DOM). All of our 10G SFP+ transceivers support this function.
Q: What is the difference between 10G SFP+ and 10G XFP transceivers?
A：First, they have different form factors, XFP is an older and bigger version, and SFP+ is an enhanced smaller form factor and has become the most popular transceiver. Second, XFP built-in CDR supports Clock Data Recover, but SFP+ usually has no CDR. Clock Data Recover is a feature that helps recover clock data when it goes missing.
