Our research investigates an optical channel deaggregation technique based on modulation format conversion that may be used in elastic optical networks (EONs) to achieve high spectral efficiency, flexibility, and high data rate. The modulation format conversion technique from 8-ary phase shift keying (8-PSK) to two simultaneous quadrature phase shift keying (QPSK) at 50 Gb / s has been simulated and investigated. 8-PSK and the converted QPSK signals are investigated and compared in terms of bit error rate (BER) and quality factor (Q-factor), and it is demonstrated that they substantially reduce the complexity of transmission and reception process, at high data rates in EON. Additionally, this approach is further exploited to tailor a protection scheme for network survivability. Channel deaggregation, which divides the channel into working and protection paths, is used to implement a dedicated path protection scheme in EON. To evaluate the effect of various network conditions such as traffic load, modulation format, and BER on EON survivability, network simulations are performed on the ARPANET network.

弹性光网络光信道解聚合调制格式转换研究

我们的研究调查了一种基于调制格式转换的光信道解聚合技术，该技术可用于弹性光网络 (EON)，以实现高频谱效率、灵活性和高数据速率。已经模拟和研究了从 8 进制相移键控 (8-PSK) 到 50 Gb/s 的两个同步正交相移键控 (QPSK) 的调制格式转换技术。在误码率 (BER) 和品质因数 (Q-factor) 方面对 8-PSK 和转换后的 QPSK 信号进行了研究和比较，结果表明它们在高数据速率下显着降低了传输和接收过程的复杂性在 EON。此外，该方法还被进一步用于为网络生存能力定制保护方案。渠道解聚，将信道分为工作路径和保护路径，用于在EON中实现专用路径保护方案。为了评估各种网络条件（如流量负载、调制格式和 BER）对 EON 生存能力的影响，在 ARPANET 网络上进行了网络模拟。
