Paper Abstract

In this paper, a 850nm-optimized dispersion-unshifted single-mode optical fiber was introduced. This type of fiber is completely compatible with G652 series fibers, but its bandwidth at 850nm wavelength has been optimized in order to fitting the potential applications. This fiber was manufactured by PCVD (Plasma-active Chemical Vapor Deposition) method. In order to increasing the 850nm bandwidth, the core-RI-profile (Refractive Index) of this fiber was designed as graded-index profile. With a piece of about 36km length fiber, some relevant geometric and optical characteristics had been got. The core diameter, MFD (Mode Field Diameter) was about 13 micron and 9.6 micron respectively. The cut-off wavelength and zero-dispersion wavelength was at 1315nm and 1323nm nearly. The attenuation at 1310nm and 1550nm was less than 0.34dB/km and 0.19dB/km respectively. With all of these results, this 850nm-optimized fiber was completely corresponding with specifications of G652 series of fibers. Meanwhile, OFLB (Over-Filled Launch Bandwidth) test showed the bandwidth at 850nm was larger than comparing to about OFL bandwidth of normal G652 fiber. Because of the pretty large 850nm bandwidth, this fiber could be possibly used at 850nm wavelength in LAN (Local Area Network) or DSN (Data-Storage Network) field. In order to validating the compatibility with G652 fibers, the splice loss between this fiber and normal G652 fiber also had been tested.
