Calculation of bends losses in single-mode fibers and the critical radius of curvature by two light sources

الملخص EN

Bending effect was studied on reached signal through single mode fiber by two light sources ( Infrared LED model IR333C-A with wavelength 940nm andpure red laser Diode model RLD63NZC5 with wavelength rate 635nm) , Measurements were conducted contacts Postal Service and the communication in Najaf the bending losses were calculated in addition to the critical radius of curvature.

These results were compared to theoretical results to find out that both results were very close.
