Gangguan Birefringence Pada Kelengkungan Serat Optik Mode Tunggal
Single mode optical fiber operation for long haul distance communication media is has rapidly developed. However, this fiber components still experienced interference with external factors that result birefringence fibers such as bending power loss and increasing wavelengths. In order to investigate the interference, a numerical simulation is set with perspective of twisted fiber disorder as a function of wavelengths using OptiFiber application. The simulation modeled various refractive indices, such as SMF-28, SMF-28e, SMF-28e +, SMF-28e + LL, and SMF-28 ULL but the same diameter and wavelength source of 1310nm and 1550nm. The quality of optical fiber interference in this operation can be known from the twisted power loss values with different variations of twisted radius. The results obtained at each SMF indicate that the greatest power loss occurs on smaller bent radius. The greatest curvature loss occurs in the SMF-28 fibre of 0,012dB/km with a radius of curvature 0,020m for a wavelength of 1310nm and the curvature loss of the 1550nm wavelength is 31,96dB/km at radius 0,020m. These data indicate that normalized frequency value strongly determines the effectiveness and stability of the optical fibre performance. The addition of wavelength can affect the fibers experiencing birefringence. The effective birefringence value at each SMF occurs at a wavelength of 1550nm indicating a slightly impaired fibre than at 1310nm wavelength.
