Transmission Transparency and Potential Convergence of Optical Network Solutions at the Physical Layer for Bit Rates from 2.5 Gbps to 256 Gbps

Popis výsledku v původním jazyce

In this paper, we investigate optical network recommendations GPON and XG-PON with triple-play services in terms of physical reach, number of subscribers, transceiver design, modulation format and implementation cost. Despite trends to increase the bit rate from 2.5 Gbps to 10 Gbps and beyond, TDM-PONs cannot cope with bandwidth requirements of future networks. TDM and WDM techniques can be combined, resulting in improved scalability. Longer physical reach can be achieved by deploying active network elements within the transmission path. We investigate these options by considering their potential coexistence at the physical layer. Subsequently, we analyse the upgrade of optical channels to 100 Gbps and 256 Gbps by using advanced modulation formats, which combine polarization division multiplexing with coherent detection and digital signal processing. We show that PDM-QPSK format is suitable for 100 Gbps systems and PDM-16QAM is more beneficial at 256 Gbps. Simulations are performed in the OptSim software environment.
