Optical fibers represent a major potential platform for quantum squeezed sensing due to the extremely low loss and perfect single-spatial-mode operation. In this work, we demonstrate two-mode intensity squeezing directly within a commercially available optical fiber, based on a four-wave mixing process. The setup operates in a quasi-continuous-wave mode using 15\u2005ns long pulses and relies on standard laser diode sources, telecommunication electro-optic modulators, and simple photo-detectors. The process is seeded by a coherent signal input, generating bright squeezed output states. Absolute noise reduction by 4\u2005dB below the classical shot-noise limit is detected directly with no post-processing, for output signal and idler pulses of 2.4\u2009\u00d7\u200910\n                    <jats:sup>6<\/jats:sup>\n                    photons in average.
