Resumen:

In this paper, two different receiver schemes based on nonreturn to zero (NRZ) modulation format to implement next generation 25 Gbps passive optical network (PON) links are compared in terms of performance. One scheme is based on the re-use of 10 Gbps PON optoelectronic components adding a DSP-based adaptive equalizer at the receiver. The other avoids the use of equalization but requires higher-bandwidth components (i.e. 25 Gbps technology developed for data centre interconnects). By means of simulations, we demonstrate that both schemes can operate through 20-km of single mode fibre in O-band achieving similar performance and power requirements. © 2018 Institution of Engineering and Technology.
