摘要： In a multiwavelength lightwave communications system automatic self-power regulation on a channel-by-channel basis is achieved with a cascade of multiwavelength amplifier modules (200), wherein each multiwavelength amplifier module in the cascade includes a plurality of pump-shared parallel fiber amplifiers (208) operated in gain-saturation and connected between an optical demultiplexer (203) and multiplexer (209). An optional first gain stage (202) improves performance with higher optical signal-to-noise ratio. By self-regulating the power in each channel, the communications system is scalable, allowing the system to grow without deleterious effects due to power spread.

摘要： In a multiwavelength lightwave communications system channel-by-channel power regulation is achieved with a cascade of inhomogeneously broadened saturated fiber amplifiers spaced along the optical fiber transmission path. In the described embodiment, inhomogeneous broadening is achieved by immersing each of the erbiumdoped fiber amplifiers in the cascade in a bath of liquid nitrogen, thereby cooling each amplifier to approximately 77 K.
