为了进一步提高系统容量和改善系统性能，我们利用外气相沉积（ＯＶＤ）工艺，设计并制作了大有效面积非零色散位移光纤，称为康宁ＬＥＡＦＴＭ光纤。这种光纤有效面积高达９５μｍ２，而普通ＮＺＤＳＦ光纤为５５μｍ２。由于大有效面积非零色散位移光纤具有较高的额定最大功率，其直接效益之一就是可改善系统信噪比和加大放大器间隔。就陆地系统应用而言，ＬＥＡＦ已被用于４５０ｋｍ长放大ＷＤＭ的传输实验中，在红段以８×１０Ｇｂ／ｓ的速率和在蓝段以４×１０Ｇｂ／ｓ的速率实现了４５０ｋｍ（５×９０ｋｍ）无误码传输。对于全光纤网络应用，ＬＥＡＦ比普通ＮＺＤＳＦ的传输距离增加了２５％。
To further increase system capacity and improve system performance, we designed and fabricated a large effective area, non-zero dispersion shifted fiber called the Corning LEAFTM fiber using an OVD process. The effective area of this fiber is up to 95μm2, while the average NZDSF fiber is 55μm2. One of the immediate benefits of a large effective area non-zero dispersion shifted fiber is its higher rated maximum power, which is to improve the system’s signal-to-noise ratio and increase amplifier spacing. For terrestrial system applications, LEAF has been used in transmission experiments of 450 km long-scale WDM with 450 km (5 ×) at a rate of 8 × 10Gb / s in the red segment and 4 × 10Gb / s in the blue segment 90km) Transmission without error code. For all-fiber network applications, LEAF transmission distance than the average NZDSF increased by 25%.
