In long-haul transmission systems, received optical powers of Individual repeaters differ significantly depending on repeater spacing. Build-out networks (BONs) have frequently been used to adjust for these differences. The development of BON-free repeaters would be advantageous from the standpoint of simplifying the installation and maintenance of transmission lines. A variable transimpedance preamplifier proposed by the authors can expand optical dynamic range and is useful for realizing BON-free optical repeaters.1 We report a 1.55-μm 565-Mb/s monolithically integrated optical repeater with a wide optical dynamic attained by use of the proposed preamplifier.
