TELLABS INC

TELLABS INC is a veteran designer of telephone and telegraph apparatus whose focus on optical networking systems, broadband access gear and interconnect modules keeps it tethered to the infrastructure layer of carriers and enterprise data centers. CIK 317771 anchors a profile of a company whose engineering teams push fiber-optic line cards, remote node shelves and management software that support long-haul, metro and enterprise transport customers as they wrestle with the demand for resilient voice and data backbones; these buyers rely on Tellabs for service assurance, field-proven hardware and a support ecosystem tuned to telecom service level agreements. Operating in a regulated industry shaped by FCC requirements for universal service, spectrum coordination and carrier interoperability, Tellabs must continuously address compliance costs, competitive pressure from larger optical vendors and the risk that capital expenditures lag the cyclical spend of telecom operators. The most recent disclosure, a Form 8-K filed in December 1999, underlines that the board still communicates material events through these filings, so view live SEC filings on Earnings Feed.
