ABSTRACT
Information signals need to be transmitted fast, efficiently and accurately. Optical fiber cables
are the transmission medium used in optical fiber communications. Optical fiber communication
has exhibited many advantages over other means of communication. However, natural and
physical environment within the vicinity where the cable is installed poses a great challenge to
signal transmission. The effect of bends on the quality of the output signal generated by a
continuous wave (CW) laser on a single mode optical fiber was investigated. A single mode
optical fiber cable was subjected to Macrobends in the range of 5mm-50mm bend radius. An
optical signal from a CW laser emitting beams in the range of 800nm-880nm was transmitted
through the cable. Transmission percentage and variation in peaks were noted and graphs plotted
corresponding to each bend radius. Transmission percentage was found to be proportional to the
size of the bend radius. Similarly, the single mode optical fiber cable was subjected to pressure
using various weights in the range of 1-6kg. The weights develop stress on the cable. The optical
signal from the CW laser was transmitted and its transmission quality analyzed. Various
transmission graphs were plotted for each pressure exerted. Transmission percentage and the
nature of peaks changed according to the weight applied. This study showed that increased
pressure resulted in increased attenuation which resulted in minimal or no signal transmission.
The single mode optical fiber cable was placed in thermal chamber where temperature was
regulated. The range of temperatures considered corresponded to the ones of Nakuru area with
changes in the range of 13 0C to 400C. An Optical signal was transmitted and various
transmission graphs were plotted for each temperature change. Transmission percentage and the
nature of peaks were noted for each temperature. The temperatures under study had no effect on the quality of the output signal since transmission graph appeared similar.
