Campus OptiX (POL) saves investment in bothCapex (Capital Expenditure)andOpex (Operational Expenditure). Specifically:

Capex Savings:POL reduces costs associated with active equipment (e.g., switches, routers), cabling, and construction by using passive optical splitters and a simplified architecture.

Opex Savings:POL lowers operational costs due to its centralized management, reduced power consumption, and lower maintenance requirements compared to traditional Ethernet-based LANs.

Option Dis incorrect because it excludes savings from active equipment, which is a significant cost component in traditional networks.
