In the 5th generation mobile fronthaul (5G-MFH), a wavelength-division-multiplexing (WDM) optical-transmission device is used to efficiently connect many remote units with fewer optical fibers. WDM optical-transmission device for 5G-MFH is required to meet technical requirements such as long-distance transmission and multi-rate operation at low cost. This paper demonstrates a proof-of-concept of WDM optical-transmission device supporting 10/25 Gbps multi-rate operation using signal-compensated optical transceivers equipped with a 10-Gbps-class-bandwidth optical receiver.
