LINBO3 10GB intensity modulator lithium niobate 5 lot
5 units of new in box lucent 2623na 10 Gbits/s Lithium Niobate Description The 10 Gbits/s Electro-Optic Modulator 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. Lucent also offers a 10 mW, CW laser with polarization-maintaining fiber (D2525P) to use as source for the modulator. The Ti-diffusion process is a standard feature on all modulator devices.The 2623CS is a single-drive, 10 Gbits/s modulator; the 2623CSA is a single-drive, 10 Gbits/s modulator with an attenuating section. Variable attenuation to >18 dB is achieved through a dc bias voltage. The package is hermetic to protect the LiNbO 3 die from the environment. Novel processing techniques now make it possible to achieve 20-year operation with little drift in the dc bias point. The modulator is tested to, and meets the intent of, TR-NWT-00468. Other standard features include Panda-type polarization-maintaining fiber (PMF) for the optical input and output fiber with FC-type connectors that are keyed to the axis of polarization. Custom designs are available.
