The effective area of an Er3+ doped fiber of 3% erbium concentration was studied experimentally by the transverse shift measurement method for the excitation of 980 and 1480 nm wavelengths and at the amplification range of 1520–630 nm. Based on experimental results, the fiber effective area was calculated. A comparative analysis and estimation of the results for different wavelengths of an Er3+ doped fiber are given.
Keywords: erbium doped optical fibers, effective area, nonlinear optical effects, WDM

Eksperimentiškai tirtas optinių šviesolaidžių su erbio priemaišomis efektyvusis plotas naudojant skersinio poslinkio matavimo metodą 980 ir 1480 nm bangos ilgių sužadinimui ir esant stiprinimo ruožui nuo 1520 iki 1630 nm. Remiantis eksperimentų rezultatais, suskaičiuotas šviesolaidžio efektyvusis plotas. Straipsnyje pateikta rezultatų lyginamoji analizė ir įverčiai skirtingiems bangų ilgiams šviesolaidyje su Er3+ priemaišomis.
