Abstract

PURPOSE:To enable superhigh-speed conversion with simple constitution by directly converting optical digital signals coded by a binary system into an optical analog signal. CONSTITUTION:The signal of optical fiber 1a is allowed to correspond to bit 4, that of optical fiber 1b to bit 3, that of optical fiber 1c to bit 2, and that of optical fiber 1d to bit 1. The signals are introduced into line collector 8 through light attenuators 6a-6d having predetermined different attenuating factors, and by adding the signals, an optical analog signal is given to optical fiber 5.
