Abstract: Disclosed is a telecommunications link having positively chirped optical signal pulses propagating in an optical waveguide fiber (52), at least a portion of which is characterized by a negative chromatic dispersion. An embodiment of the invention is a semiconductor laser source (46) in combination with negative dispersion optical waveguide fiber (52). The sourc e (46) of the chirped signal pulses is selected to have predominantly adiabati c chirp as evidenced, in the case of a DFB laser (46), by a gain compression factor in the range of 4 x (10 power of -23)x(m power of 3) to 30x (10 power of -23) x(m power of 3). Eye closure penalty and bit error rate are maintain ed low for link lengths having cumulative dispersion parameter times distance product of the order of thousands of ps/nm. Optimum laser extinction ratio i s found to be in the range of 5 to 10 dB, although extinction ratios as high a s 20 dB are contemplated.

Abstract: Disclosed is a telecommunications link having positively chirped optical signal pulses propagating in an optical waveguide fiber, at least a portion of which is characterized by a negative chromatic dispersion. An embodiment of the invention is a semiconductor laser source in combination with negative dispersion optical waveguide fiber. The source of the chirped signal pulses is selected to have predominantly adiabatic chirp as evidenced, in the case of a DFB laser, by a gain compression factor in the range of 4 x 10 m to 30 x 10 m . Eye closure penalty and bit error rate are maintained low for link lengths having cumulative dispersion parameter times distance product of the order of thousands of ps/nm. Optimum laser extinction ratio is found to be in the range of 5 to 10 dB, although extinction ratios as high as 20 dB are contemplated.

Abstract translation: 公开了一种电信链路，其具有在光波导光纤中传播的正向啁啾光信号脉冲，其至少一部分的特征在于负色散。 本发明的实施例是与负色散光波导光纤组合的半导体激光源。 啁啾信号脉冲的源选择为主要是绝热的啁啾，如在DFB激光器的情况下所证明的，增益压缩因子在4×10 -3 m 3至30×10 5的范围内， -23>米<3>。 对于具有累积色散参数乘以距离乘积数千ps / nm的链路长度，闭眼罚分和比特错误率保持较低。 发现最佳激光消光比在5至10dB的范围内，尽管可以考虑高达20dB的消光比。
