A compact and low-cost device that emulates a 100-km single-made fiber opti
c link at 1550 nm is proposed. The device, composed of a chirped fiber grat
ing and a monitor coupler, is analyzed by simulation and experimentally pro
ved. A chirped fiber grating synthesis procedure Is also introduced. (C) 19
