What is 10 Gigabit Optical Module?

First of all, let's understand what is 10Gbps optical module. 10Gbps optical module is an optical module with a transmission rate of 10Gbps, also known as 10G optical module, which has two kinds of packages, SFP+ and XFP, and its common package form is SFP+ package. With the advantages of fast transmission speed, high bandwidth and stable signal, they are widely used in data centers, high-performance computing and other fields.

Difference between single-mode fiber and multi-mode fiber

Single-mode fiber (SMF) allows only a single light mode to be transmitted in the fiber, and the light source is a laser light source. The cable color is mostly yellow, and the transmission distance of single-mode fiber is relatively long.

Multi-mode fiber (MMF) supports multiple optical modes transmission, the transmission distance is usually below 2km, the light source is LED light source, OM2 is usually used in Gigabit optical modules, OM3 is used in 10Gbps and above optical modules, the center wavelength is usually 850nm, the transmission distance of multi-mode fiber is relatively short.

Therefore, when choosing the optical fiber for 10 Gigabit optical module, you need to choose the appropriate fiber type according to the actual application scenario. If it is a single-mode optical module, which needs to transmit high-speed data in a long distance range, single-mode fiber should be selected; if it is a multi-mode optical module, which transmits high-speed data in a shorter distance range, multi-mode fiber should be selected.Walsun, as a professional module manufacturer, can provide 1G-400G optical modules, fiber optic cables and other products, and we welcome your purchase!
