摘要： Multimode optical fiber systems with adjustable chromatic modal dispersion compensation are disclosed, wherein the system includes a VCSEL light source and primary and secondary optically coupled multimode optical fibers. Because the VCSEL light source has a wavelength spectrum that radially varies, its use with the primary multimode optical fiber creates chromatic modal dispersion that reduces bandwidth. The compensating multimode optical fiber is designed to have a difference in alpha parameter relative to the primary multimode optical fiber of -0.1
摘要翻译：公开了具有可调色度模式色散补偿的多模光纤系统，其中该系统包括VCSEL光源以及主和次光耦合多模光纤。由于VCSEL光源具有径向变化的波长谱，因此与主多模光纤的使用会产生色度模式色散，从而降低带宽。补偿多模光纤被设计成相对于主要多模光纤具有-0.1≤Δalpha≤0.9的α参数差。这用于产生与色度模式色散相反的模式延迟。通过使用选择长度的光学耦合到主多模光纤的输出端的补偿多模光纤来实现补偿。补偿多模光纤可以被配置成对弯曲不敏感。

摘要： According to one embodiment, an optical sensing system may include a gated optical amplifier, one or more triggering devices, and an optical coupler. The gated optical amplifier can receive a pulse signal and transform the pulse signal into an amplified pulse signal having an amplified peak portion. The triggering devices can control the gated optical amplifier such that the gated optical amplifier is in the lossy state while the baseline portion of the pulse signal is transformed and the gated optical amplifier is in the gain state while the peak portion of the pulse signal is transformed. The amplified pulse signal can be transmitted to the sensing optical fiber and a sensed optical signal can be received, when the sensing optical fiber is connected to the optical coupler. Optionally, a second pulse signal and the sensed optical signal can be combined and detected with a coherent balanced detection technique.
摘要翻译：根据一个实施例，光学感测系统可以包括门控光放大器，一个或多个触发装置和光耦合器。门控光放大器可以接收脉冲信号并将脉冲信号转换成具有放大峰值部分的放大脉冲信号。触发装置可以控制门控光放大器，使得门控光放大器处于损耗状态，而脉冲信号的基线部分被变换，并且门控光放大器处于增益状态，同时脉冲信号的峰值部分被变换。当感测光纤连接到光耦合器时，放大的脉冲信号可以传输到感测光纤并且可以接收感测的光信号。可选地，可以用相干平衡检测技术组合并检测第二脉冲信号和感测到的光信号。

摘要： Multimode optical fiber systems with adjustable chromatic modal dispersion compensation are disclosed, wherein the system includes a VCSEL light source and primary and secondary optically coupled multimode optical fibers. Because the VCSEL light source has a wavelength spectrum that radially varies, its use with the primary multimode optical fiber creates chromatic modal dispersion that reduces bandwidth. The compensating multimode optical fiber is designed to have a difference in alpha parameter relative to the primary multimode optical fiber of -0.1 ≤ Δα ≤ -0.9. This serves to create a modal delay opposite to the chromatic modal dispersion. The compensation is achieved by using a select length of the compensating multimode optical fiber optically coupled to an output end of the primary multimode optical fiber. The compensating multimode optical fiber can be configured to be bend insensitive.
