Potential of the high modal bandwidth OM4 glass multimode fiber for the multi-services concept

摘要

In this paper, we report new results dealing with the wavelength multiplexing transmission scheme over the OM4 high modal bandwidth multimode fiber. Fiber bandwidth measurements both at 850 nm and 1300 nm clearly show the huge bandwidth/length product of this fiber. The simultaneous transmission of a high data rate baseband signal (10 GbE) at 850 nm and a radiofrequency MultiBand Orthogonal Frequency Division Multiplexing Ultra-Wide Band (band group 5-10 GHz) MB-OFDM UWB signal (480 Mbps) at 1300 nm is presented. The measurements - Bit Error Rate (BER) for the 10 GbE signal and Error Vector Magnitude (EVM) for the MB-OFDM UWB signal - that are hereby reported show safe results under the requirements of the corresponding communication standards; they give this architecture an affordable approach for home/office networking at high data rate in a joint fixed and wireless environment.
