Description

Representing the latest advancements in high-speed lithium niobate technology, the 40 Gbits/s electrooptic modulator 2625C is designed for long-wavelength, single-mode, external amplitude modulation applications. It uses an integrated Mach-Zehnder configuration 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 eliminates the need for demanding, high-speed performance from the laser and reduces its cost.

2625C inherently offers the capability to adjust the phase of the voltages on the electrodes, which produces zero-chirp modulation operation. The modulator is tested to, and meets the intent of, TR-NWT-00468.
