The New Tapered Fiber Connector and the Test of Its Error Rate and Coupling Characteristics

Abstract

Since the fiber core is very small, the communication fiber connector requires high precision. In this paper, the effect of lateral deviation on coupling efficiency of fiber connector is analyzed. Then, considering the fact that optical fiber is generally used in pairs, one for transmitting data and the other for receiving, the novel directional tapered communication optical fiber connector is designed. In the new connector, the structure of the fiber head is tapered according to the signal transmission direction. In order to study the performance of the new connector, several samples were made in the laboratory of corporation CDSEI and two testing experiments were done. The experiment results show that compared with the traditional connector, for the same lateral deviation, the coupling efficiency of the tapered connector is higher and the error rate is lower.

Theoretical study of the dispersion effects occurring at optical fiber connections

“…At the same time, published sources [5][6][7][8][9][10] do not provide information on the effect of the investigated power redistribution processes on form, and, consequently, duration of the optical signal.…”

“…However, no consideration of the effect of signal form change in the points of fiber connection was provided in these studies. Instead, a considerable attention is paid to improvement of OF connections in terms of reducing errors at the receiving side [8]. There are papers devoted to metrological aspects of study of attenuation occurring in the OF connection points [9,10].…”

“…These studies also do not take into consideration a phenomenon of signal form distortion caused by redistribution of signal power in an OF connection point. An extensive list of references devoted to the mentioned issues is given in [5][6][7][8][9][10]. However, these studies do not consider the effect of fiber connection points on the optical signal length and magnitude of introduced dispersion.…”

“…Suppose that the regeneration section consists of N faceto-face lengths. Then, proceeding from expressions (7) and (8), it is proved by induction that the signal at the output of the N-th face-to-face length (that is, at the input of the photodetector) will have a total PDF:…”

“…en, using Gauss optical theory, the coupling efficiency equation is obtained. In [10], the error rate and coupling characteristics of the new tapered fiber have been studied. In [11], a PIN photodiode array is proposed to receive space light directly.…”
