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 研究結果表明對于高速率傳輸系統(tǒng), pmd對脈沖的影響在時域上表現為脈沖形狀的展寬,這種展寬是隨機的;而同步幅度調制是在時域上,將發(fā)生形變的脈沖通過振幅調制,恢復原形,從而提高脈沖的傳輸性能。
