摘要

本文提出了一种用于高速多路波分复用（ＷＤＭ）陆上级联掺铒光纤放大器（ＥＤＦＡ）光纤通信系统的色散补偿方案，其特点是：利用特殊设计的色散位移光纤ＳＤＤＳＦ（零色散波长λ０≈１．６μｍ，色散斜率Ｓ＿０＝０．０５ｐｓ／ｋｍ／ｎｍ２），在１５５０ｎｍ处产生－２～－４ｐｓ／ｋｍ／ｎｍ的色散，以避免ＩＴＵ－ＴＧ．６５３色散位移光纤在多路复用时的四波混频（ＦＷＭ）效应；并利用ＩＴＵ－ＴＧ．６５２标准单模光纤（非色散位移光纤ＮＤＳＦ）在１５３０～１５７０ｎｍ（ＥＤＦＡ工作带宽）范围内，有效地补偿ＳＤＤＳＦ所引入的负色散。此方案可使单路数据率高于１０Ｇｂ／ｓ的波分复用系统，经１０００ｋｍ传输后因色散引入的眼图恶化量仍＜１ｄＢ。

Abstract

A new dispersion compensation method for high-speed terrestrial cascaded Erbium-Doped Fiber Amplifier wavelength division multiplexed （WDM） optical transmission systems is proposed in this paper. By means of specially designed dispersion-shifted fiber（SDDSF） with zero dispersion wavelength around 1. 6μm and dispersion slope S

=0. 05ps/km/nm

-2～-4ps/km/nm dispersion is generated at 1550nm to avoid severe four-wave mixing in WDM systems using ITU-T G. 653 DSF. The positive dispersion of ITU-T G. 652 standard single-mode fiber is utilized to compensate for the negative dispersion of SDDSF over 1530～1570nm （EDFA bandwidth ）. With this method

dispersion induced eye opening penalty could still be less than 1dB after 1000km fiber transmission in systems with bit-rate higher than 10Gb/s per channel.
