它表明，由模式色散引起的多模光纤链路的带宽限制，可以通过使用在超过3 dB带宽的频率范围内的通带调制克服。传输1.25 Gb/s超过500米的近最坏的情况下62.5 /spl μ/m多模光纤实现使用两个副载波复用信道在850 nm波长。
It is demonstrated that the bandwidth limitation of multimode fiber links arising from modal dispersion can be overcome by using passband modulation in the frequency range beyond the 3 dB bandwidth. Transmission of 1.25 Gb/s over 500 m of near-worst case 62.5 /spl mu/m multimode fiber is achieved using two subcarrier multiplexed channels at the 850-nm wavelength.
