Nokia C111991.C2B ESA24 expansion shelf assembly for optical transmission systems.

The Nokia C111991.C2B is an ESA24 (Expansion Shelf Assembly) module designed for Nokia optical transmission and networking equipment. This shelf assembly provides physical housing and backplane connectivity for line cards and system modules within Nokia’s telecommunications infrastructure platforms.

The ESA24 is typically deployed in carrier-grade optical transport networks and metro aggregation applications. It serves as a sub-rack or expansion unit that extends the capacity of Nokia’s core transmission chassis, allowing network operators to scale their deployments by adding additional card slots and interfaces.

This module is part of Nokia’s legacy optical networking portfolio. While newer platforms may have superseded some deployments, the ESA24 remains relevant for operators maintaining existing Nokia optical infrastructure or requiring compatible expansion capacity for established network architectures.
