摘　　要：通过计算机模拟发现在可传输双模的三包层色散补偿光纤中如果抑制ＬＰ０２模，而仅传输ＬＰ０１模时能在一个较窄的带宽内产生大于数千ｐｓ／ｎｍ·ｋｍ的负色散，并且具有较大的模场直径、较小的弯曲损耗和偏振模色散，另外还具有较小的温度波长漂移以及同其它色散补偿光纤一样大小的损耗。Computer stimulation shows if the LP 02 mode is suppressed and only the LP 01 mode is transmitted in a two mode dispersion compensating fiber of three clad dings, more than thousands ps/nm·km negative dispersion values can be achieved. Having a large mode field, small bending loss, small polarization mode dispersion and small temperature drift, and the loss value as other dispersion compensated fibers, the fiber of this kind appears to be a promising dispersion compensating fiber.
