Q: What is the 3rd Generation Optical Distribution Network (ODN)?
A: Traditional ODN deployments inevitably require a large amount of fiber smelting work, requiring a large number of well-trained and skilled employees to operate with expensive fiber smelting equipment, and the deployment cost is high. At present, ODN is developing in the direction of pre-connectivity and digitalization. The third-generation ODN solution uses pre-connection technology and digital image recognition technology to greatly improve the ODN deployment efficiency and port resource accuracy, making the ODN network an easy-to-deploy, visual, and manageable intelligent optical distribution network.
Q: Get a quick overview of FTTx/FTTC/FTTB/FTTH?
A: What is FTTx?
FTTx stands for "Fiber To The x", which is a general term for optical fiber access in optical fiber communication, and x represents the destination of the optical fiber line. For example, x = H (Fiber to the Home), x = O (Fiber to the Office) to the office, x = B (Fiber to the Building). FTTx technology ranges from the central office equipment of regional telecommunication equipment rooms to user terminal equipment, including optical line terminal (OLT), optical network unit (ONU), and optical network terminal (ONT).
According to the location of the optical network unit ONU at the user end, there are various types of FTTx, which can be divided into fiber-to-the-box (FTTCab), fiber-to-the-curbside (FTTC), fiber-to-the-building (FTTB), fiber-to-the-home (FTTH), fiber-to-the-office (FTTO) and other service forms. U.S. carrier Verizon refers to FTTB and FTTH together as Fiber-to-the-Premises (FTTP).
