About This Part
The Nokia 474903A.101 is a high-performance SFP28 optical transceiver designed for robust 25 Gigabit Ethernet (25GbE) connectivity. As a critical component within Nokia's extensive portfolio of optical networking solutions, this module adheres to the compact SFP28 form factor, enabling high-density deployments in data centre interconnects, enterprise networks, and telecom infrastructure. Its primary function is to facilitate reliable, high-speed data transmission over single-mode fibre optic cables, supporting a substantial link distance of up to 30 kilometres. Engineered for demanding operational environments, the Part Number 474903A.101 features an industrial temperature (I-temp) rating, ensuring stable performance across a wide range of ambient conditions. This makes it suitable for outdoor cabinets or unconditioned spaces where temperature fluctuations are common. With a data rate of 25Gbps, it provides the necessary bandwidth for next-generation network upgrades, offering a cost-effective path to higher speeds compared to 10GbE while being more efficient than 100GbE for specific link requirements. This Nokia SFP28 transceiver is typically deployed in 25GbE-capable network equipment, including switches, routers, and optical transport platforms, where high-bandwidth, long-reach single-mode connectivity is essential. It serves as a vital link in various network architectures, from interconnecting racks within large data centres to extending metro-area networks and providing backhaul for access networks. Telecommunication operators, internet service providers, and large enterprises leverage this module to upgrade their existing 10GbE infrastructure to 25GbE, addressing growing bandwidth demands without a complete overhaul. Its 30km reach capability is particularly valuable for campus networks, distributed data centres, or connecting remote points of presence (PoPs) where direct fibre runs are feasible. The industrial temperature rating further expands its utility, allowing deployment in challenging environments such as roadside cabinets, outdoor enclosures, or industrial facilities, where standard commercial-grade transceivers might fail. This module effectively solves the challenge of delivering robust, high-speed optical connectivity over significant distances in diverse operational settings.
