What type of data transport does the Cisco ONS series routers utilize?

The Cisco ONS (Optical Networking System) series routers utilize metro optical transport technology, which is designed for high-capacity data transfer over optical fibers in metropolitan areas. This type of transport leverages wavelength division multiplexing (WDM) techniques to increase the capacity of optical fiber networks by allowing multiple signals to be transmitted simultaneously over the same fiber strand.

Metro optical transport is particularly suited for environments where high-speed data transmission is required, such as interconnecting data centers, providing services to enterprises, or backhauling data traffic for service providers. This technology enhances efficiency and scalability, making it an ideal choice for modern networking needs in urban environments.

The other options are not relevant to the functionality of the Cisco ONS series. Wireless fiber connection is not a standard term and does not accurately describe the technology used. Satellite data transfer involves satellite communication which is quite different from fiber optics in terms of latency and speed. Standard copper cabling, while still used for many networking applications, does not provide the same high bandwidth and scalability as optical solutions.
