“…Compared with PAM, carrierless amplitude/phase modulation (CAP) [4], [5] and optical orthogonal frequency division multiplexing (OOFDM) [6] can further improve system spectral efficiency and flexibility without greatly increasing the digital signal processing (DSP) required. Additionally, power efficiency has become more important for the communications and networks sector to reduce the carbon footprint of the Internet.…”

For the first time, simulations have been performed to evaluate and compare the link power budget and power dissipation of 100 Gb/s carrierless amplitude and phase modulation-16/64 (CAP-16/64) and 16/64-quadrature amplitude modulation-orthogonal frequency division multiplexing (16/64-QAM-OFDM) systems over feedforward error correction (FEC) enhanced single mode fiber (SMF) links using an 18.6 GHz bandwidth directly modulated laser, for both single channel and two coarse wavelength division multiplexing (CWDM) channel cases. It is shown that single channel CAP-16 and 16-QAM-OFDM links can successfully support transmission over 5 km SMF, with a power dissipation of 2 times that of a 4 25 Gb/s NRZ system. Even when the loss of the optical multiplexing/demultiplexing operations is considered, the use of two CWDM channels supports transmission over 5 km SMF with CAP-16 and 16-QAM-OFDM. The CWDM systems do not increase transceiver power dissipation greatly.

“…The comparison of CAP and DMT modulation using DM-VCSELs has been carried out experimentally over MMF. As shown in Figure 5 [24], [25]. The results show that for lengths up to 30 km of SMF, the 2D-CAP-16 scheme without forward error correction (FEC) offer good performance and have half the power consumption of optical orthogonal frequency division multiplexing (OOFDM) schemes at 28 Gb/s data rate.…”

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 leads to cost increment issue which is caused by employment of multiple optical components. Therefore, implementation of advanced modulation format using a single wavelength channel has become a preference to increase spectral efficiency by increasing the data rate for a given transmission system bandwidth. Conventional advanced modulation format however, involves a degree of complexity and costly transmission system. Hence, carrierless amplitude phase (CAP) modulation format has emerged as a promising advanced modulation format candidate due to spectral efficiency improvement ability with reduction of optical transceiver complexity and cost. The intriguing properties of CAP modulation format are reviewed as an attractive prospect in optical transmission system applications.

“…To increase the spectral efficiency of these links, higher-order modulations formats have been proposed [11,12]. Recently, different direct detection schemes have been investigated for advanced short reach applications such as orthogonal frequency-division multiplexing (OFDM) [13,14], multitone (DMT) modulation [15,16], Pulse amplitude modulation (PAM) [17][18][19], and CAPmodulation [20,22].…”

Wavelength-division multiplexed (WDM)carrierless amplitude/phase (CAP) modulation is proposed for1.8 Tb/sfor short reach optical communication system. The system uses 16 channels, each operates at 112 Gb/s. A single-band (SB) CAP and multiband (MB) CAP are adopted for each channel as advanced modulation format with high spectral efficiency. The system performance at C and O operating bandsare investigated withchannel spacing of 100 GHz.The system is simulated using OptiSystem14.0 software package and the results reveal that the maximum allowable distance at BER of 〖10〗^(-3) is 3.45km and 2.11 km for SB-CAP and MB-CAP operating at C-band with 0 dB laser power, respectively. These values to be compared with 4.5 km and 1.8 km, respectively, for O-band operation.
