“…In the propagation method, the time of flight of an optical pulse from an LD is simply measured. A fanout device, which converts an eight-fiber ribbon to eight individual fibers, is spliced to this fiber ribbon by using the mass-fusion splice method [6]. Four fanout devices are used at the input and output of this fiber ribbon for light injection and detection.…”

The influence of fiber parameters on skew has been experimentally clarified by using single-mode 16-fiber ribbons with different fiber parameters. The skews are measured for fibers in 16-fiber ribbons. It is found that not only the relative refractive index difference 1 but also the ratio of the mode field diameter to the core diameter influence the skew. The time of flight is measured for 16-fiber ribbons under several temperature and strain values. Although the time of flight is influenced both by temperature and strain, it is confirmed experimentally that skew is independent of fiber parameters. These results indicate that the skew of a fiber ribbon under a uniform environment can be determined from fiber parameter differences. Previously proposed equations for evaluating the skew are used to design fibers in a fiber ribbon in order to realize fiber ribbons with the desired skew value.Index Terms-Computer networks, optical fiber, optical fiber cables, optical fiber communication, local area networks.

A new stuffing-pulling fusion technique for mass splice of single-mode fiber ribbon is presented. The fiber spliced region is pulled after the fiber end faces are fused and stuffed against each other. The characteristic feature of this technique is that the stuffing and pulling strokes are varied based on observation of the fiber end face gaps for every splice. This technique can reduce splice loss to approximately 50 % of that realized by the conventional method and can eliminate splice failure due to fiber end face gap variance. A new mass fusion splice machine based on this method has been manufactured, and an average splice loss of 0.024 dB is attained using this splice machine. This agrees with calculated result.

“…So, for the construction of subscriber systems using fiber ribbons, a low-loss and reliable splice method is necessary for the mass splice of single-mode fiber ribbons. In the conventional method [5] for mass splicing, it is impossible to estimate losses at every splice. Nevertheless, large splice losses would probably appear when fiber ribbons are spliced many times.…”

A loss estimation method for mass splicing of singlemode fiber ribbons is presented. This method is based on measuring fiber axis discrepancy and the stuffing and pulling stroke of fiber end faces at the fusion splice, which can be obtained by processing the fiber end face image. Measurement accuracy of fiber axis discrepancy and splice loss estimation error, which is influenced by this measurement, are investigated theoretically and experimentally. It is found that splice loss estimation error is mainly caused by measurement error of the fiber axis discrepancy. Calculated distribution of fiber axis discrepancy measurement error agrees with experimental results. The distribution of splice loss estimation error also agrees with that found experimentally. Average splice loss estimation error of 0.039 dB is attained with a standard deviation of 0.036 dB.
