Mini External Modulation Optical Transmitter module
Description
The photonic integrated design of the product integrates a 40mw DFB laser, a thin film LiNbO3 intensity modulator, a low-noise microwave amplifier and a drive control circuit to achieve photoelectric conversion of RF signals and is suitable for external modulation links for small-size microwave photon transmission. ITU standard channel is optional, the module insertion loss is less than 5dB, the noise factor 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, hermetic package ,the operating temperature is -55℃ ~ 70℃, no external circuit requirements. Increase optional microwave amplification to reduce link noise factor. 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. Meet the requirements of miniaturization and high reliability. Can be customized according to customer requirements.
