JDS Uniphase Deal Scrutinized

Antitrust enforcers are questioning whether JDS Uniphase Corp.’s proposed $19.7-billion acquisition of E-Tek Dynamics Inc. would hurt competition in the expanding market for fiber-optic components, people familiar with the government’s review say. JDS Uniphase is “fully cooperating with the Justice Department and providing them with whatever information they require to evaluate the transaction,” a spokesman said. JDS Uniphase closed up $5.63 at $127, while E-Tek fell $8.25 to close at $230, both on Nasdaq.
