The benefits of large effective area fibers are higher power handling capability for improved system signal to noise ratio (SNR), and longer amplifier spacing.

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。

The ratio of effectual emitter area to base area of a FFJ is 2-3 times greater than a usual transistor and the output power-impedance product is 5-10 times greater.

与通常晶体管相比，FFJ的有效发射极面积对基极面积之比值提高2～3倍，输出功率-阻抗乘积提高5～10倍。
