We experimentally demonstrated a 5-channel 125-GHz-grid wavelength division multiplexing (WDM) transmission over 6,400-km Raman amplified ultra large effective area fiber (ULAF) with 848-Gbps/carri…
With the increasing demand of bandwidth, a higher capacity communication system is required for optical short link and access network. Intensity modulation/direct detection (IM-DD) is considered as…
