In this paper, the authors deal with the establishment of optical network between the waystations. SDH, PDH and control communication are the three equipments provided at each waystation. SDH equipments of each station are interconnected through OFC in the form of ring topology. Fibcom STM-1 is used as SDH (Synchronous Digital Hierarchy) equipment in order to split the whole bandwidth into number of individual channels. These channels are assigned to each waystation. Bandwidth of the assigned channels is further split into sub channels by PDH (Plisiochronous Digital Hierarchy) equipment.
