Abstract:
In the fiber optic cables (FOCs) with stranded loose tube design, components like glass reinforced plastic (GRP), gel and buffer tube material, play a significant role in the smoke emission. As the fiber count in a certain FOC design increases - thus increasing the number of the buffer tubes, the amount of gel and a thicker GRP – it becomes difficult for that FOC to meet the recommended light transmission of 60% in the smoke density test according to EN 61034-2. This paper summarises the results of the smoke density tests on various armored stranded loose tube flame retardant FOCs. The FOCs discussed in this paper were tested for smoke density according to the IEC Standard EN 61034-2. The light transmission characteristics of single- and double metallic armored cables are discussed.
