日立公司（ＨｉｔａｃｈｉＬｔｄ）日前以ＩＣ形式制造了一种集选择电路、触发电路和调制驱动电路为一体的光传输机电缆 ,该系统通过这些电路与低电压驱动的半导体光调制组件相结合 ,是世界上第一根以４０Ｇｂｉｔ／ｓ工作的光传输机电缆。它用速度惊人的铟 -磷异质双极晶体管?
Hitachi Ltd. (HitachiLtd.) In the form of IC to create a selection circuit, trigger circuit and modulation drive circuit as one of the optical transmitter cable, the system through these circuits and low-voltage-driven semiconductor optical modulation components combined is the world On the first to 40Gbit / s optical transmitter cable. Is it using an incredibly fast indium-phosphorus heterojunction bipolar transistor?
