Abstract

Single-mode fibers, for near 1.55-μm operating system wavelength with triangular ( $\\alpha = 1$ ), parabolic ( $\\alpha = 2$ ), and step-index ( $\\alpha =\\infty$ ) profiles were fabricated by the modified chemical vapor deposition (MCVD) technique. Optical transmission losses under zero-tension and with the basket weave under 10, 40, and 70 gm tensions were measured, respectively. Fundamental mode size was obtained as a function of wavelength by using the transverse offset technique. The triangular-profile fiber shows lower loss (≃0.25 dB/km at 1.55μm) under zero-tension and a larger spot size than the other fibers. However, the basket weave test showed the triangular-profile fiber incurred higher loss with tension than the other profiles.
