What Is the Difference Between Singlemode QSFP+ and Multimode QSFP+?
The singlemode QSFP+ and multimode QSFP+ here mean the QSFP+ transceivers which work at different types of optical fibers, ie singlemode QSFP+ will work with singlemode fiber, while multimode QSFP+ will work with multimode fiber. So, what’s the different between them? And what should we notice when using them? Which one should I choose? In this article, we will have a discussion around this topic. Singlemode QSFP+ vs. Multimode QSFP+ Singlemode QSFP+ Singlemode fiber (SMF) has much tighter tolerances for optics used. The core is smaller and the laser wavelength is narrower. This means that SMF has the capability for higher bandwidth and much longer distances in transmission. Singlemode QSFP+ (SMF QSFP+) works mainly in 1310nm wavelength and is mostly used in long distances transmission. There are many different types of Singlemode QSFP+, and different type can achieve different transmission distance, such as 500m, 1km, 2km, 10km and 40km. he color of compatible fiber optic patc...
