We report on the experimental realization of a highly-chirped dissipative soliton (DS) oscillator with all-fiber cavity consisting of a short single-mode fiber part (for mode locking via nonlinear polarization evolution) and a long PM fiber part (for generation of highly-chirped DS) that enabled to increase cavity length to L ~ 90 m. Stable DS pulses dechirped to ~ 200 fs are generated with maximum energy of ~ 20 nJ. The energy limit is shown to be defined by the onset of Raman conversion of the DS spectrum. The Stokes pulse reaching comparable energy inside the cavity and does not break the soliton stability. Higher DS energy is possible by means of a core enlargement, corresponding experiments are also performed.
