About This Part
The Nokia 474902A.101 is a high-performance SFP28 optical transceiver designed for robust 25 Gigabit Ethernet applications. As a key component within the optical networking product family, this module adheres to the SFP28 form factor, ensuring compatibility with a wide array of industry-standard networking equipment. Its primary function is to provide reliable, high-speed data transmission over single-mode fiber optic cables. Key technical specifications include a 25Gbps data rate, operating at a wavelength of 1310nm, and supporting a Long Reach (LR) transmission distance of up to 10 kilometers. This module is built to an Industrial Temperature (I-Temp) specification, making it suitable for deployment in environments with challenging thermal conditions. Furthermore, the inclusion of AOSD (Active Optical Sub-Assembly with Digital Diagnostics Monitoring) functionality allows for real-time monitoring of critical parameters such as optical output power, input power, temperature, and supply voltage, crucial for proactive network management and fault isolation. The Nokia 474902A.101 typically features an LC duplex connector for fiber optic interfacing. This SFP28 transceiver is pivotal for modern data center interconnects, enterprise network upgrades, and telecom access and metro networks requiring increased bandwidth. It is commonly installed in 25G Ethernet switches, routers, servers equipped with 25GbE Network Interface Cards (NICs), and various other high-capacity networking platforms. Industries such as telecommunications, cloud computing, financial services, and large-scale data analytics leverage this module to address growing demands for faster data throughput and lower latency. It effectively solves the problem of network congestion in high-density environments and facilitates the migration from 10GbE to 25GbE infrastructure, offering a cost-effective upgrade path that maximizes existing fiber plant utilization. This module serves as an essential upgrade from 10G SFP+ transceivers, enabling a significant boost in per-port capacity without requiring a complete overhaul of the optical fiber cabling infrastructure for distances up to 10km.
