IPG’s EAR Series is a line of universal broadband, high power, randomly or linearly polarized, single-mode fiber amplifiers covering the spectral range from 1540-1600 nm. The series includes 1-30 W saturated output power versions. These user friendly and highly efficient 19” rack mounted devices are designed for maintenance-free applications over a temperature range of 0°C to 50°C. The EAR Series is a basic series optimized for randomly or linearly polarized (LP) signals with >1 GHz linewidth. Amplifiers optimized for single frequency (SF) signals are also available on request. These amplifiers can be used for a variety of applications including components stress testing, free-space communications, detection systems and other laboratory and in-field applications.
