本光双偏振光发射机评估板可用于复杂的诸如PM-QPSK, QAM, OFDM光信号的生成. 主板集成了高速的双偏振QPSK调制器, 射频信号驱动器以及自动偏压控制器, 并提供了光信号眼图幅度和抖动性能的调节. 单电压供电, **小的尺寸, 较简的用户界面, 使得它非常适合实验和开发人员在实验室调试或二次开发使用, 且******.
DESCRIPTION
The dual polarization IQ/QAM Transmitter is a high performance modulation evaluation unit that allows user to produce optical **s with complex modulation schemes (PM-QPSK, QAM, OFDM). It integrates high bandwidth PM-QPSK modulator and high speed RF drivers capable of dealing with data rate up to 128 Gbps. It features an embedded bias controller that allows to automatically set the modulator operating point.
FEATURES
