据日本《O Plus E》1993年第160期报道,日本东芝公司已研制成把GaAs IC和光器件共同封装在一个管壳内的光纤通信用的半导体模块,型号有以2.5Gbit/s传输速度激励的发射模块“TOLD 345D/TXl”,“同395S-TXl”和接收模块“TOAD345-RX3”三种,并开始出售样品。 发射模块采用DFB激光器,“TOLD345S-TX”振荡波长为1.3μm,传输距离约为80km,“同395S-TXl”振荡波长为1.55μm,传输距离约10km。 作为接收器件的“TOAD345-RX3”接收模块,采用高灵敏度、宽带InGaAs APD。样品价格:1.3μm的收发模块组件为200万日元;1.55μm收发模块组件为250万日元。
According to Japan’s “O Plus E” No. 160 of 1993 reported that Toshiba Japan has developed into a GaAs IC and optical devices packaged in a common package of optical fiber communication semiconductor module, the model has 2.5Gbit / s speed of excitation The launch module “TOLD 345D / TXl”, “with the 395S-TXl” and the receiving module “TOAD345-RX3” three, and began to sell the sample. The transmitting module adopts DFB laser, the oscillation wavelength of TOLD345S-TX is 1.3μm, the transmission distance is about 80km, the oscillation wavelength of the same with 395S-TX1 is 1.55μm, and the transmission distance is about 10km. As a receiver device “TOAD345-RX3” receiver module, using high-sensitivity, broadband InGaAs APD. Sample price: 1.3m transceiver module components for 2 million yen; 1.55μm transceiver module components for 2.5 million yen.
