Nokia C111323 NP8S1-B optical network protection switch module.

The Nokia C111323, designated NP8S1-B, is a network protection switch module designed for optical transport systems. This unit provides automatic protection switching functionality to ensure network resilience and service continuity in the event of fibre path failures or equipment faults.

The NP8S1-B module is engineered for deployment within Nokia’s optical networking platforms, where it monitors primary and secondary transmission paths and executes rapid switchover to maintain uninterrupted data flow. Protection switching is a critical function in carrier-grade networks where service availability requirements are stringent.

This is a legacy Nokia optical transport component, reflecting earlier generations of the company’s transmission portfolio. It remains relevant for operators maintaining existing Nokia optical infrastructure or requiring compatible spares for installed network equipment.
