Nokia C111825 ESB24-D expansion shelf backplane module for optical transport systems.

The Nokia C111825 ESB24-D is an expansion shelf backplane module designed for Nokia optical transport and telecommunications infrastructure. This component provides the interconnection framework within expansion shelves, enabling communication between line cards, tributary modules, and system controllers in high-capacity network equipment.

The ESB24-D backplane is typically deployed within Nokia’s optical networking platforms, serving as a critical passive or semi-active component that routes signals and power between installed modules. It forms part of the shelf assembly infrastructure in DWDM, SDH/SONET, or carrier Ethernet transport systems.

This is a legacy Nokia component associated with earlier generations of optical transport equipment. While these systems remain operational in many carrier networks globally, the platform has been superseded by newer Nokia photonic and packet optical solutions. The ESB24-D remains relevant for operators maintaining existing network infrastructure or requiring spare components for deployed systems.
