The company went public in July 1980, ending the year with sales of $43.7 million.

1982: Tellabs introduces the telecommunications industry's first viable echo canceler system.
In 1983, with the opening of Tellabs' fourth facility in Puerto Rico, it seemed Tellabs' growth would continue uninterrupted.

By 1993, the TITAN accounted for over $80 million of Tellabs' annual revenues.
By 1994, the TITAN could manage 688,000 simultaneous phone calls.
Tellabs was ideally situated to capitalize on the industry's ongoing fluctuations. For example, Tellabs teamed up with Advanced Fibre Communications, Inc., and introduced the CABLESPAN 2300 Universal Telephony Distribution System in 1994.
