Mini External Modulation Optical Transmitter Module

This product is integrated 40mw DFB laser, thin film LiNbO3 intensity modulator, low-noise microwave amplifier and drive control circuit to achieve photoelectric conversion of RF signals which is suitable for external modulation links for small-size microwave photonic transmission. ITU standard channel is optional while optical loss is less than 5dB and noise figure of the photoelectric link without microwave amplification is less than 32dB with high-speed photoelectric detector. The bending radius of the optical fiber is less than 10mm with hermetic packaging. The operating temperature is -55℃ ~ 70℃ without external circuit requirements. The better optional microwave amplification can reduce link noise figure. It has the characteristics of wide frequency band, high integration, small size, light weight, no need for external circuit, wide operating temperature range, small bending radius of optical fiber and strong environmental adaptability. It can be customized according to customer requirements.
