Fiber birefringence measurement
WebThe birefringence or the optical anisotropy of fibers is of a complex nature as it is a composite of intrinsic birefringence, which is based on the fact the oriented rod-shaped … WebAug 1, 2001 · Fig. 2. Experimental setup. The OTDR pulses modulates a 1550-nm DFB laser via a pulse generator. After amplification, the pulses are continuously Rayleigh-backscattered as they propagate down the fiber, and the emerging backscattered light is directed by the circulators onto the OTDR detector. An AOM is used to suppress the …
