Ultra-Low Jitter Oscillators Optimized for Optical DSP Applications
超低抖动振荡器针对光学DSP应用进行了优化

Fiber optic cables are one of the most important conduits for transporting information through telecommunication networks. Information is transmitted by modulating the amplitude and the phase of light using a technique called coherent optical transmission. Optical signals are transmitted back and forth through the same fiberoptic cable by using optical transceivers at both ends of the cable. Optical transceivers are designed to allow both a transmitter and a receiver to cohabitate. This allows the creation of a full duplex link on a bidirectional fiber optic cable.
光缆是通过电信网络传输信息的最重要的管道之一，石英晶振，使用一种称为相干光传输的技术，通过调制光的振幅和相位来传输信息。通过使用光缆两端的光收发器，光信号通过同一光缆来回传输。光收发器被设计成允许发送器和接收器共存。这允许在双向光缆上创建全双工链路。

Digital Signal Processors (DSP) used inside optical transceivers at both ends of the fiber optic link, allow increased transmission speeds all the way to 800G, simpler circuitry and improved optical performance. Digital Signal Processors require high frequency, ultra-low jitter clock oscillators, VCXOs and VCSOs as a frequency reference.
光纤链路两端的光收发器中使用的数字信号处理器(DSP)可以将传输速度一直提高到800G，简化电路并提高光学性能。数字信号处理器需要高频、超低抖动时钟石英晶体振荡器、VCXOs和VCSOs作为频率基准。

Raltron has a complete line of oscillators designed to be compatible with or to serve as a reference design for some of the foremost optical DSPs used in optical transceivers.
