随着互联网用户的持续增多,社交网络、云计算、视频网络等的快速发展,用户对带宽的要求越来越高。光器件小型化、低功耗已成必然趋势在持续扩大的光通信市场中,手机基站和光纤到户是最受关注的领域,而市场对光器件小型化、低功耗的呼声越来越高。为了顺应市场要求,三菱电机开发出新的40公里10Gbit/s EML芯片,以及改善TEC制冷器的性能来降低器件功耗;封装形式也从 With the continuous increase of Internet users, the rapid development of social networks, cloud computing and video networks, the bandwidth requirements of users are getting higher and higher. Small size and low power consumption of optical devices have become an inevitable trend In the ever-expanding optical communications market, mobile base stations and FTTH are the areas of most concern. As the market increasingly calls for miniaturization and low power consumption of optical devices high. In order to meet the market requirements, Mitsubishi Electric developed a 40 km 10Gbit / s EML chip, as well as improve the performance of TEC cooler to reduce device power consumption; package from
