Abstract

This letter discusses a fiber design for lump Raman amplification (LRA) at 1270nm wavelength used in passive optical networks (PON) using hybrid-Raman amplifiers, which are previously proposed. For simplicity, refractive-index profile is assumed to be step-index. Gain and optical signal noise ratio (OSNR) are calculated as a function of Δ. Considering a fiber fuse, we discuss a design of fibers used for lump Raman amplification. To realize a compact LRA, we propose a use of hole-assisted fibers (HAF) when high power laser is available.
