Nokia Baseband 6630 KDU 137 848/11 (21P) R2C

The KDU 137 848/11 (21P) R2C is a highly reliable 21-port multi-service expansion interface board custom-developed by Nokia exclusively for the Baseband 6630 baseband unit. Featuring multi-standard service bearing and carrier-grade stable transmission, it is mainly designed for scenarios including CPRI/eCPRI signal backhaul of 5G base stations, government and enterprise private line access, and edge network multi-service aggregation. It serves as a key supporting component for Baseband 6630 to achieve flexible networking and business expansion.

1. Core Compatibility & Application Scenarios

This interface board is a dedicated expansion card for Baseband 6630, which can be seamlessly integrated into the convergence layer between the baseband unit and the transmission network, efficiently undertaking various service data interaction requirements of 5G base stations.

Core Application Scenarios: CPRI/eCPRI optical-to-electrical signal access for 5G macro base stations/micro base stations; E1/Ethernet private line bearing for government and enterprise customers at the base station side; local offloading and backhaul of data at edge computing nodes; centralized aggregation of multi-services at the edge of carrier metro networks.
Compatibility Advantages: Deeply compatible with Baseband 6630, plug-and-play without complex debugging; supports hot-swapping and online service configuration, allowing board replacement or parameter adjustment without shutting down the baseband unit to avoid base station service interruption; compatible with 4G/5G dual-mode service transmission, meeting the needs of smooth network upgrade.
