Page 5: Chapter 1 Introduction
RF amplifiers is user-adjustable. Variable optical attenuators (VOAs) and power monitors enable completely automatic optical output power control and stabilization. The MX10C series includes an external loop-back cable for the driver RF output and modulator RF input ports, which provides the opportunity to use an external driver, if desired. -

MX10C, MX40C Series of Optical Transmitters Chapter 4: Operating Instructions Chapter 4 Operating Instructions 4.1 Control Loop Diagram The following diagram shows the control loops added to the block diagram. From this picture, the user can see how the power monitors and VOA are used to provide stability and control to the whole system. - Page 17 MX10C, MX40C Series of Optical Transmitters Chapter 4: Operating Instructions Tap here to adjust crossing set point from -100 to +100. Tap here to optimize output swing. Tap here to adjust maximum output swing in Digital mode. Figure 17 Digital Amplifier Mode Settings The Max Output Swing field allows the user to set the peak-to-peak output voltage of the amplifier, assuming the amplifier input signal is large enough to cause the amplifier to start clipping.
- Page 18 MX10C, MX40C Series of Optical Transmitters Chapter 4: Operating Instructions In the Analog mode, the Max Output Swing is locked at the maximum set point of 7.0 V , so the amplifier can drive the modulator linearly with minimal distortion. However, in order to do this, the user must supply a signal with small enough amplitude so the amplifier does not saturate, or clip.

Here the user can control the laser wavelength and choose whether or not to use the dither feature to stabilize the wavelength. Turning the dither off will result in lower phase and intensity noise, but the wavelength may drift slightly over time. - Page 21 MX10C, MX40C Series of Optical Transmitters Chapter 4: Operating Instructions In "STEP 1GHz" mode you can edit the fine-tuning frequency offset in steps of 1 GHz. Figure 25 Changing the Fine-Tuning Step Size Note that while the L-band and C-band lasers can have their frequency adjusted by increments as small as 1 MHz, the laser’s actual tuning accuracy is not this fine.
