Optical Post Amplifiers

Optical Post Amplifiers

MACOM's post-amplifiers convert differential or single-ended analog signals to high-speed digital outputs, using a chain of limiting amplifiers. Many of these products feature signal detection circuitry, programmed using an off-chip resistor. They are available in a number of speeds, covering 155 Mbps to 12.5 Gbps applications.
