SAN JOSE, Calif., Sept. 8 -- JDS Uniphase, a provider of communications test and measurement solutions and optical products for telecommunications service providers, cable operators and network equipment manufacturers, announced today a definitive agreement to acquire Agility Communications Inc., a provider of tunable laser solutions for the optical network. Agility Communications is privately held with approximately 90 employees and headquarters in Santa Barbara, Calif. The acquisition is subject to customary closing conditions and regulatory approvals and is expected to happen by the end of the year; the terms were not disclosed. JDS Uniphase officials say the potential benefits of Agility's monolithic platform are its ability to fully integrate a tunable laser with a modulator via a highly scalable semiconductor wafer process, that its platform can enable tunable 2.5 Gb/s SFP and 10 Gb/s XFP form factors, that it has switching speeds of less than 10 ms and is less sensitive to shock and vibration.
