AbstractWe demonstrate a radio-over-fiber-based hybrid wavelength-division-multiplexed/time division multiplexed passive optical network (PON) to transmit 5 Gbps data rate to serve 32 subscribers. A broadband light source (BLS) is realized by mutual injection locking between two Fabry-Perot laser diodes at the transmission section to seed wavelength-division-multiplexed channels. Mutual injection locking technique is used to enhance the performance over single Fabry-Perot laser diode and 15  dB/Hz improvements in relative intensity noise(RIN) is realized in our proposed network system. All-optical up-conversion of a 10-GHz 1.25 Gbps on off keying radio frequency (RF) signal is achieved using one single-arm Mach-Zehnder modulator (MZM). Transmission performance over 25-km single mode fiber is investigated. Low bit error rate with enhanced eye-diagram is obtained in our proposed system. As a result, the radio over fiber (ROF)-based wavelength-division-multiplexed/time division multiplexed PON set up employing mutually injection locked Fabry-Perot laser diodes can be a better choice in high speed long-haul optical communication system.

In the present paper, we have been modeled numerically and parametrically the high and best performance functions of optical add drop multiplexers (OADMs) for ultra wide wavelength division multiplexing technique with ultra wide space division multiplexing technique in advanced optical communication networks and photonic networking over the assumed set of parameters. Moreover, we have analyzed and investigated the maximum time division multiplexing (MTDM) and soliton transmission techniques to be processed to handle bit rate either per link or per channel for cables of multi-links (20-120 links/core). Where maximum number of transmitted channels in the range of 1000-4800 channels are processed to handle the product of bit rate either per channel or per link for cables of multilinks of silica cable core fabrication material. The MTDM or soliton transmission bit rates either per link or per channel are also treated over wide range of the affecting parameters under the ambient temperature variations. Also, the performance characteristics of the OADMs are taken as the major interest in optical networks to handle maximum transmission bit rates for the supported subscribers.

We review the main results obtained with our recently introduced passively fundamental mode-locked Er : Yb :glass lasers mainly in the context of telecom applications, and we discuss their key enablers. Specifically, we focus on the aspects of the lasers for application in the time-domain for optical time-division multiplexing and in the wavelength domain for dense wavelength-division-multiplexing.
