Description
This FBG Interrogator is designed and manufactured with an in-house tunable laser from OptoChip Ltd. It supports 4~16 channels of fiber sensing data synchronous modulation, with a maximum demodulation frequency of 1kHz.
The wavelength tuning range is between 8~10nm within the C-band, and the minimum sweep step is 10pm (step customization available). It has high wavelength accuracy, and a fast demodulation speed. In addition, it provides a user-friendly host computer software that can support fast evaluation, as well as rapid system setting-up and testing. It also features several communication protocols to facilitate customers' subsequent development and system integration. This product is the ideal choice for applications in the field of fiber optic sensing.
