About This Part
The Part Number 473206A, known as the Nokia 473206A, represents a critical component within Nokia's advanced fixed access portfolio. This module, likely a Fiber Optic Service Terminal (FOST) line card, is engineered for deployment within Optical Line Terminal (OLT) platforms, serving as the interface between the service provider's network and numerous fiber-to-the-x (FTTx) subscribers. Its primary function involves aggregating and distributing high-speed broadband services over passive optical networks (PON). Operating within a modular chassis, this unit provides multiple optical ports, each capable of supporting a significant number of Optical Network Units (ONUs) or Optical Network Terminals (ONTs). Key technical specifications typically include robust support for GPON (Gigabit Passive Optical Network) and potentially XGS-PON (10 Gigabit Symmetrical Passive Optical Network) protocols, offering downstream data rates up to 2.5 Gbps for GPON and 10 Gbps for XGS-PON, with corresponding upstream rates. It manages optical wavelengths, often utilizing 1490 nm for downstream and 1310 nm for upstream in GPON, ensuring efficient and reliable data transmission across the last mile. Furthermore, these modules incorporate advanced traffic management, Quality of Service (QoS) mechanisms, and robust security features to ensure optimal performance and subscriber experience, making them indispensable for modern broadband infrastructure. This Nokia module is predominantly installed in central office environments or remote aggregation points within telecommunications networks. It forms the backbone of FTTx deployments, supporting a wide array of services including residential broadband internet, IPTV, VoIP, and dedicated business connectivity. Network operators, internet service providers (ISPs), and large enterprise campuses utilize the 473206A to extend high-capacity fiber optic services directly to end-users. It is typically integrated into Nokia's OLT chassis series, such as the ISAM FX or Lightspan platforms, where it scales network capacity and enhances service delivery capabilities. The module effectively solves the challenge of providing scalable, high-speed, and reliable last-mile connectivity, enabling operators to meet growing demand for bandwidth-intensive applications. It serves as a crucial upgrade path for legacy copper-based access networks (e.g., DSL) and facilitates the expansion of existing fiber footprints, ensuring future-proof infrastructure.
