چکیده
We experimentally demonstrate successful performance of VCSEL-based WDM link supporting advanced 16-level carrierless amplitude/phase modulation up to 1.25 Gbps, over 26 km SSMF with spectral efficiency of 4 bit/s/Hz for application in high capacity PONs.

Optical Transmission System Employingcarrierless Amplitude Phase (cap) Modulation Format
Multiple wavelength channels can be used for implementing transceiver modules in optical transmission system network in order to increase spectral efficiency. However, it leads to cost increment which is caused by employment of multiple optical components. Therefore, implementation of advanced modulation format has become an option to further increase spectral efficiency. But apparently, it inv...
متن کاملA Carrierless Amplitude Phase (CAP) Modulation Format: Perspective and Prospect in Optical Transmission System
Received Dec 14, 2016 Revised Apr 15, 2017 Accepted Apr 30, 2017 The explosive demand of broadband services nowadays requires data communication systems to have intensive capacity which subsequently increases the need for higher data rate as well. Although implementation of multiple wavelengths channels can be used (e.g. 4 × 25.8 Gb/s for 100 Gb/s connection) for such desired system, it usually...

In this paper, we propose new methodology to enhance the QoS in cost and energy efficient WDM/OFDM PON system. In this, the WDM technique supports more number of ONU and the OFDM technique provides high spectral efficiency and flexible sub-channel bandwidth allocation. Here, we have reduce BER at ONU by using the post dispersion compensation technique inorder to reduce the chromatic dispersion ...

We experimentally demonstrate the performance of a 10 Gb/s subcarrier multiplexed (SCM) wavelength-division multiplexed (WDM) passive optical network (PON) using 2.5 Gbaud 16-QAM transmission signals. Digital signal processing (DSP) and square-root raised cosine (SRRC) pulse shaping enable both the uplink and downlink channels to achieve net spectral efficiencies up to 2.8 bit/s/Hz per channel ...
