An important aspect of coherent optical satellite communication technology is the power consumption of the employed laser systems. Therefore, an enhanced wall-plug efficiency of the optical amplifiers is required. We present the prototype design (technology readiness level 4, TRL) and optical characterization of a 10-channel amplifier system for the use in WDM optical communication infrastructures operating at 1 μm wavelength. Combining the experience of in-house manufactured fiber components and laser systems, an all-fiber amplifier solution was designed to realize an overall wall-plug efficiency of around 30\%. All ten input channels were simultaneously amplified up to a combined power of 100W.
