Our results show that pmd induces pulse broadening randomly in high bit - rate optical fiber communications ; the synchronous amplitude modulation control may correct directly any position change of timing jitter and soliton interaction , so the transmission distance and pulse quality will increase further 研究結(jié)果表明對(duì)于高速率傳輸系統(tǒng), pmd對(duì)脈沖的影響在時(shí)域上表現(xiàn)為脈沖形狀的展寬,這種展寬是隨機(jī)的;而同步幅度調(diào)制是在時(shí)域上,將發(fā)生形變的脈沖通過(guò)振幅調(diào)制,恢復(fù)原形,從而提高脈沖的傳輸性能。
