摘要
本文根据色散受限中继段长度的计算，对实际工程中１５５０ｎｍ波长２．５Ｇｂｉｔ／ｓ系统进行计算比较得出啁啾声引起的色散不容忽视，它使２．５Ｇｂｉｔ／ｓ成为色散受限系统。对１３１０ｎｍ波长６２２Ｍｂｉｔ／ｓ系统，当使用多纵模激光器时，往往也会成为色散受限系统。
This paper presents that the dispersion caused by chirp is not neglectable, with which the 2. 5 Gbit/s system for 1550 nm becomes dispersion limited system. It is likely that the 622 Mbit/s system for 1310 nm also becomes dispersion limited system when multi-longitudinal mode laser is used.
