The optical fiber transmission system include a light source and a light detector and optical fiber. This paper is detailed estimated link loss budget along optical fiber cable between source and destination at YAESAGYO Township in Myanmar. Firstly Losses in optical fiber links, cable loss connector loss and splice loss are explained and typical standard values defined by IEEE are shown in this paper. The link loss budget is the total amount of losses, insertion loss along the optical cable. It is estimated by calculating the losses of all the devices through along the cable to get the estimated total end-to-end loss along the fiber. In this paper the minimum link loss of optical cable, 12 cores 4wire are designed and calculated for repeaterless optical transmission system in YAESAGYO Township in Myanmar.
