Design and development of fiber optics laser power transfer standard under scientific collaboration MOU between NIMT and PTB

摘要

Up to date, fiber optics laser systems are the most efficient way to carry information and very important in the field of telecommunication in Thailand. Typical optical fiber systems composed of laser sources, optical fibers as the transmission mediums, and detectors as receivers, where the most basic measurement necessary is optical power. To maintain quality and standard of information transmission, optical power measurement calibration is very important. The objective of this research was to design and development of InGaAs detectors, to use as an optical power transfer standard in the wavelengths where the optical fiber communication systems are operated. The design and development of the transfer standard under scientific collaboration between the national institute of metrology Thailand (NIMT) and Germany (PTB) will be presented.
