Broadband fiber ASE light test source in third transmission window designated for high spectral resolution Bragg gratings measurements was realized. It was achieved by the use of erbium doped fiber in the ring laser configuration with the beam splitter made in fused taper technology. The fiber and EDFA properties were measured to optimize the fiber length for maximum amplification. System was pumped by 110 mW 980 nm laser diode. The measured ASE output power was 12 dB better than in the reference SLED source in 1520- 1550 nm range.
