WebDec 31, 2024 · In this paper, we design a silica-cladded Germania-doped ring-core fiber (RCF) that supports orbital angular momentum (OAM) modes. By optimizing the fiber structure parameters, the RCF possesses a near-zero flat dispersion with a total variation of <±30 ps/nm/km over 1770 nm bandwidth from 1040 to 2810 nm for the OAM 1,1 mode. A … Web- For long range communication system the loss limit was set to 20 dB/Km (was ~ 1000 db/Km or higher at that time!). - Pure form of Silica, by reducing impurities i.e., the optical losses were not due to glass itself, but impurities in it. - Limit met by doping titanium in fused core and pure fused
