TL;DR: In this paper, an experimental investigation on the influence of connectors in a large core step-index plastic optical fiber-based link, in terms of the available bandwidth, has been performed, where a vertical-cavity surface-emitting laser with a small launch numerical aperture was used, while a number of subscriber connectors were placed into different positions of a 50m link.
Abstract: An experimental investigation on the influence of connectors in a large core step-index plastic optical fiber-based link, in terms of the available bandwidth, has been performed. A vertical-cavity surface-emitting laser with a small launch numerical aperture was used, while a number of subscriber connectors were placed into different positions of a 50-m link. Significant performance degradation was observed when the connectors were placed at the beginning of the link. The impact was of minor importance when they were placed at a distance from the transmitter which was longer than the coupling length.

TL;DR: In this paper, an electronic optical imaging system consisting of a computer-controlled CCD array with 576 x 384 detection elements and 14 bits of digitization was used to obtain internal and external light intensity distributions for diffusing optical fiber tips used with photodynamic therapy and laser angioplasty.
Abstract: An electronic optical imaging system consisting of a computer-controlled CCD array with 576 x 384
detection elements and 14 bits of digitization is presented. The system is used to obtain internal and
external light intensity distributions for diffusing optical fiber tips used with photodynamic therapy
and laser angioplasty. Significant intensity distribution variations were observed between fiber tips
from 5 different sources. The effect of launch numerical aperture on the measured light distributions
is also presented.
