A Study on the Development of Core Systems & EYDFA Parts for FTTH Broadcast Overlays

Abstract

In this study, erbium ytterbium doped fiber amplifier components and core systems for fiber to the home broadcast overlays are developed and evaluated to ensure stable high-power light even during long-distance data transmission in broadcast networks. Consequently , data transmission in the broadcasting network is found to be low in loss, long-distance transmission is deemed possible, and stable optical signals can be amplified using domestic equipment instead of expensive foreign equipment. The tools developed in this study provide an opportunity to reduce dependence on overseas products by allowing domestic technology, which lacks optical amplifier technology, to compete with overseas products at a low price. In the future, these tools are expected to accommodate more members from the optical communication field and be applied to various fields that use high-power light.
