摘要

通过结合密集波分复用(DWDM)技术，可以进一步增强RoF系统的带宽利用率和超高速通信。本文设计并仿真了高速1Tbps的40通道DWDM-RoF系统模型，其中每个通道以25gbps的速率传输数据。比较了用于该系统的掺铒光纤放大器(EDFA)和半导体光放大器(SOA)在不同传输距离下通道间距为0.1 nm和0.2 nm时的性能。不同情况下的q因子和光信噪比(OSNR)值已被报道，并且观察到SOA作为后放大器时表现为线性且优于EDFA。

Performance analysis of an ultra high capacity 1 Tbps DWDM-RoF system for very narrow channel spacing

A RoF system can further be enhanced by incorporating the dense wavelength division multiplexing (DWDM) technique for bandwidth utilization and ultra high speed communication. In this paper the model for a high speed of 1Tbps, a 40-channel DWDM-RoF system has been designed and simulated where each channel carries data at a rate of 25 Gbps. The performance of and erbium doped fiber amplifier (EDFA) and semiconductor optical amplifier (SOA) for the system has been compared for extremely narrow channel spacing of 0.1 nm, and 0.2 nm at different transmission distance. The Q-factor and optical signal to noise ratio (OSNR) values have been reported for different cases and it is observed that SOA performs linearly and better than EDFA when employed as post amplifier.
