that also includes 10 Gbits/s and 20 Gbits/s versions.
Representing the latest advancements in high-speed lithium niobate technology, the 40 Gbits/s electro- Features
optic modulator is designed for long-wavelength, single-mode, external amplitude modulation applica-tions. It uses an integrated Mach-Zehnder configura- tion to convert single polarization CW light from a semiconductor (DFB) laser into a time-varying optical output signal. Using the source in the CW mode elim- ■ Thin-film, 50 Ω termination in package for minimal inates the need for demanding, high-speed perfor-mance from the laser and reduces its cost.
The dual-drive design inherently offers the capability ■ Tested to Telcordia Technologies * 468 to adjust the phase of the voltages on the electrodes, ■ Angled interfaces for minimal optical reflections which produces zero-chirp modulation operation. The modulator is tested to, and meets the intent of, Benefits

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are abso-lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
