Lucent朗訊 10 Gbs 鈮酸鋰電光調(diào)制器 單驅(qū)動 帶寬 16GHz
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 LiNbO3 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.
