To provide higher bit rate services to users economically, we proposed the Subcarrier Digital Modulation Passive Optical Network (SDM-PON). SDM-PON has biased and clipped signal sending schemes. The biased signal sending scheme creates a completely positive signal by adding a direct current (DC) to the electrical modulated subcarrier, and then converts it into an optical signal. The clipped signal...
Optical burst mode receivers are an inherent part of the Passive Optical Network (PON) and Optical Switched Access Network (OSAN). We previously implemented optical burst mode receivers with AC-coupling and DC-coupling using off-the-shelf components, and showed that AC-coupling offers better performance. We then proposed an optical burst mode receiver with a transfer function Gn(s)=1-Hn(s) (Hn(s):...
To economically provide higher bit rate services to users, we previously proposed a Subcarrier Digital Modulation Based Passive Optical Network (SDM-PON), and showed the feasibility of a 16-QAM SDM-PON using a bias signal sending scheme. We next proposed a clipped signal sending scheme for SDM-PON to decrease sending power, and three methods for regenerating an original QAM signal from the clipped...
To economically provide higher bit rate services to users, we previously proposed the Subcarrier Digital Modulation based Passive Optical Network (SDM-PON). We also showed the feasibility of a 16-QAM SDM-PON that constantly provides the service data rate of 1 Gbps to each user, in which ONU biases the QAM signal higher so that it is entirely positive before converting into an optical signal (bias...
This paper proposes a Subcarrier Digital Modulation based Passive Optical Network (SDM-PON) architecture to economically provide higher bit rate services to users. As a first step, we assume that 16-QAM is used as a digital modulation, and service bit rate of 1 Gbps is constantly provided to each user. To examine its feasibility, we first discuss an electrical SDM-PON that yields comprehensive studies...
