Networking Modules

Network modules are hardware components that plug into modular routers, switches, or chassis-based systems to provide additional ports, processing capacity, or protocol support. They allow network operators to scale bandwidth and connectivity without replacing the entire chassis, making them cost-effective for expanding carrier, enterprise, and data center networks.
