About This Part
The Nokia 474943A.102 is a specialized QSFP28 to SFP28 25G Adapter, designed to facilitate seamless interoperability within high-speed data centre and telecommunications networks. This passive adapter allows a single 25 Gigabit Ethernet (25GbE) SFP28 optical transceiver or direct attach cable (DAC) to be inserted into a Quad Small Form-Factor Pluggable 28 (QSFP28) host port. Its primary function is to enable connectivity from a 100GbE QSFP28 port to a 25GbE SFP28 device, optimizing port utilization and providing flexible deployment options. Technically, it bridges the physical interface gap, allowing 25G SFP28 modules to operate in QSFP28 cages, which are typically designed for 100GbE applications. This ensures compatibility across different generations and speed requirements of network infrastructure, maintaining signal integrity for 25GbE data rates. This Nokia adapter, Part Number 474943A.102, finds critical application in modern data centres and enterprise networks where a mix of 100GbE and 25GbE infrastructure coexists. It is typically deployed in high-density network switches, routers, and server Network Interface Cards (NICs) equipped with QSFP28 ports. Its primary use cases include connecting 25GbE-enabled servers, storage arrays, or other network devices to switches that predominantly feature 100GbE QSFP28 uplinks or downlinks. This solution is invaluable for telecom operators, cloud service providers, and large enterprises seeking to optimize their network architecture without undertaking a complete hardware overhaul. It effectively solves the challenge of interoperability, allowing organizations to leverage existing 100GbE QSFP28-based equipment while gradually integrating 25GbE components, thereby extending the utility of their current investment and facilitating a phased upgrade strategy.
