A GPON network consists of two major active transmission components, which are; OLT (abbreviation is Optical Line Termination) and optical network unit (ONU) or optical network termination (ONT). The advanced version of OLT and ONT/ONU have triple-play GPON services, and for this, it uses packaged optical fiber modules. These modules are called GPON SFP transceivers. This blog is for introducing you to the basics of SFP GPON modules.

Optical modules (transceivers) provide data exchange in telecommunication networks. The main task of transceivers is to convert electrical signals into optical signals for further information transmission via a fiber-optic communication line (FOCL). The 40G QSFP optical module is a QSFP based product designed for high-density applications. Compared to standard SFP + optical modules, the port density is higher, and the overall system cost is lower. It has four data transmission channels, and the transmission rate of each channel is about 10Gbps. Simultaneous transmission of four channels can achieve a transmission speed of 40 Gbps.
