摘要

An upgrade scheme using identical sending lights and local lights for optical amplifier systems based on homodyne detection is described. Optimum receiving loss for maximizing the SNR is analytically derived for the proposed configuration where the local taped lights are low level to avoid a sending power decrease. Derived formulas describing the optimum loss condition and the maximum SNR show that 10Gbit/s systems can be cost effectively upgraded to 40 Gbit/s systems with the same repeater spacing.
