 Product introduction

HC-PLM series pulse modulation and amplification module integrates semiconductor optical amplifier (SOA), pulse erbium-doped fiber amplifier (EDFA) and its supporting temperature control and modulation circuits, and can output optical pulse signals with the narrowest pulse width of 2 ns and peak power of 100 W. At the same time, a built-in pulse signal source can be selected, which has the characteristics of fast rise time, high pulse extinction ratio, good stability and convenient use, so that it becomes an ideal choice for generating and amplifying pulsed light in various optical fiber sensing systems, and can also be applied to quantum communication systems, semiconductor testing and other aspects.
