Cisco was the first company to provide which product commercially?

Remote access devices were developed by various companies, and Cisco was not the first to provide them commercially.

Fibre-optic networking technology predates Cisco's commercial router offerings, with other companies and research institutions pioneering its development.

Cisco Systems was founded on the development of multiprotocol routers, which allowed different computer networks to communicate by translating between various network protocols. They were the first to commercialize such routers, significantly contributing to the development of the internet.

Wireless networking emerged much later than Cisco's founding and initial product, with various companies contributing to its commercialization.
