About This Part
The Nokia 3AL82161AA is a high-performance SFP28 optical transceiver designed for 25 Gigabit Ethernet applications. As a key component within Nokia's extensive portfolio of networking equipment, this module adheres to the SFP28 form factor, ensuring compatibility with industry-standard SFP28 ports. Its primary function is to facilitate high-speed, short-reach data transmission over multimode fiber optic cables. Specifically, the Part Number 3AL82161AA operates at an 850nm wavelength, supporting 25GBASE-SR protocol for reliable data rates of 25 Gbps. When deployed with OM4 multimode fiber, it achieves link distances of up to 100 meters, while OM3 fiber supports distances up to 70 meters. This transceiver features a duplex LC connector interface and incorporates Digital Diagnostics Monitoring (DDM) capabilities, enabling real-time monitoring of critical parameters such as optical output power, optical input power, laser bias current, temperature, and supply voltage, ensuring robust network performance and simplified maintenance. This Nokia SFP28 transceiver is predominantly deployed in high-density data center environments, enterprise networks, and telecom access or aggregation layers where increased bandwidth is critical. It is integral to connecting 25G-capable switches, routers, and server network interface cards (NICs), forming the backbone for intra-rack and inter-rack connectivity over short distances. Cloud service providers and large enterprises leverage the 3AL82161AA to overcome bandwidth bottlenecks, enabling efficient server-to-switch and switch-to-switch links that are essential for modern virtualized and containerized application architectures. For telecom operators, these modules facilitate the upgrade of existing 10G infrastructure to 25G, supporting the escalating demands of 5G backhaul and fixed-line broadband services. It effectively replaces or upgrades legacy 10G SFP+ transceivers, providing a significant performance boost while maintaining a compact form factor for port density optimization.
