Multi-vendors G.654.E fibres field trials for 400G terrestrial transport systems were demonstrated. The evaluation works carried out by China Unicom for high bitrate terrestrial transport application are introduced. Test results in factories and fields are analyzed detailed.
We propose a computational-efficient CapEx model capturing key cost factors to analyze packet- and DWDM- based metro networks. Study on a real network using market cost figures supports evolution towards DWDM under fast traffic growth.
A novel radio-over-fiber (ROF) scheme simultaneously to modulate and transmit 10-Gb/s baseband and 60-GHz microwave signals on a single wavelength using single-sideband (SSB) modulation technique is proposed and verified by simulation. The scheme is based on a Dual-Parallel Mach-Zehnder Modulator (DPMZM). The scheme can carry the microwave signals on either the upper sideband (USB) or the lower sideband...
