Product introduction
These series optical detection module integrates two matched analog PIN detectors with high bandwidth and high linearity and a low-noise broadband transimpedance amplifier. It has the characteristics of high gain, high sensitivity, optional coupling mode and high common-mode rejection ratio, which can effectively reduce the common-mode noise of input light and improve the signal-to-noise ratio of the system. The power supply of the module is positive 12 V, the input of the module is a common single-mode optical fiber, the error of the length of the optical fiber is less than 1 mm, and the electrical signal is output from the SMA/2.92 mm port. The module is mainly used in the fields of coherent optical communication, laser radar, optical fiber coherent tomography, optical fiber sensing system and the like.
