We present experimental demonstrations of in-building impulse radio (IR) ultra-wideband (UWB) link consisting of 100 m multi mode fiber (MMF) and 4 m wireless transmission at a record 4 Gbps, and a record 8 m wireless transmission at 2.5 Gbps. A directly modulated vertical cavity surface emitting laser (VCSEL) was used for the generation of the optical signal. 8 m at 2.5 Gbps corresponds to a bit rate--distance product of 20; the highest yet reported for wireless IR-UWB transmission.
我们展示了由100米多模光纤（MMF）和4米无线传输组成的室内脉冲无线电（IR）超宽带（UWB）链路的实验演示，其传输速率达到创纪录的4 Gbps，以及在2.5 Gbps速率下实现了创纪录的8米无线传输。采用直接调制垂直腔面发射激光器（VCSEL）来产生光信号。2.5 Gbps速率下8米的传输距离对应的比特率-距离积为20，这是无线IR-UWB传输中迄今报道的最高值。
