いて、電気信号る光信号に変換する発光素子とそ
の光信号の媒体である光フアイバの間に、透過帯
が素子の発光スペクトルよりもそれぞれ長波長側
と短波長側にずれた二枚のバンドパスフイルタを
配置したことを特徴とする発光素子モジユール。 In a transmission module having a semiconductor light-emitting element, a transmission band is formed between the light-emitting element that converts an electrical signal into an optical signal and the optical fiber that is the medium of the optical signal, with a transmission band on the longer and shorter wavelength side than the emission spectrum of the element. A light emitting element module characterized by arranging two bandpass filters shifted to the side.
