Onu lays optical cables
It is the optical terminal device in the fiber access network, which provides users with multiple service interfaces. Therefore, ONU can transmit optical signals into electrical signals and vice versa. SFU (Subscriber-Facing Unit): designed for individual users, providing basic connectivity for a single home or office in fiber-optic networks. Connectivity Needs: Opt for models with VoIP support or other specific features, such as Wi-Fi or PoE.

GPON Passive Optical Networking System
GPON uses passive optical network (PON) is a fiber-optic access architecture in which a single optical fiber from a central location is shared by multiple end users through one or more passive optical splitters in series (cascaded). 984 is the series of standards that define the architecture and operation of gigabit -per-second–capable passive optical network (GPON). It is commonly used to implement the link to the customer (the last kilometre, or last mile) of fibre-to-the-premises (FTTP) services, using a. Passive Optical Network (PON) stands as a foundational technology in the evolution of modern telecommunications, serving as the cornerstone for high-speed fiber-optic networks. Central to the GPON system is the Optical Line Terminal (OLT), the core device responsible for aggregating data streams, managing Optical Network Terminal/Unit (ONT/ONU) devices, and performing application distribution and network management.

Concept of extinction ratio of optical transmitter signal
The extinction ratio is the ratio of the average optical power for transmitting signals 1 to the average optical power for transmitting signals 0 under the worst transmission conditions. One parameter, extinction ratio, is used to describe optimal biasing conditions and how efficiently available laser transmitter power is converted to modulation power. Although specifications are defined by industry standards and test method-ologies loosely described, historically it has been. More significantly, the most crucial parameter for characterizing an optical transmitter's performance in the SDI video setting is its extinction ratio (ER).
