讨论了使用窄线宽激光器和直接检测接收机的频移键控(FSK)和差分相移键控(DPSK)系统的色散限制。研究发现，这些限制很大程度上取决于接收器的配置。接收器必须包括光学鉴频器，例如马赫-曾德尔干涉仪，以及干涉仪输出处的平衡光电探测器对或单个光电探测器。对于在1310 nm优化的单模光纤上1550 nm的传输，根据调制格式和接收器配置的不同，在10 Gb/S下1分贝闭眼损失的距离从20到70公里。
Chromatic dispersion limitations for frequency-shift keying (FSK) and differential phase-shift keying (DPSK) systems using narrow-linewidth lasers and direct-detection receivers are discussed. The limitations are found to depend strongly on the receiver configuration. The receiver must include an optical frequency discriminator, such as a Mach-Zehnder interferometer, and either a balanced photodetector pair or a single photodetector at the interferometer output. For transmission at 1550 nm over 1310-nm optimized single-mode fiber, the distance for 1-dB eye closure penalty at 10 Gb/s ranges from 20 to 70 km, depending on the modulation format and the receiver configuration.<<ETX>>
