Time-division-multiplexing using pulse position locking for 100 Gb/s applications

Time-division-multiplexing using pulse position locking for 100 Gb/s applications.

Recently, there is a great interest in pushing communication technologies to 100 Gb/s. However, there are still many challenges to perform high speed (> 40 Gb/s) clock and data recovery, and data time-division-multiplexing (TDM). Here, we propose and numerically analyze an asynchronous optical packet retimer using parabolic or sinusoidal phase modulation and linear dispersion. This scheme is na...

Picosecond Pulse Generation and Its Applications in High-Speed Optical Time Division Multiplexing Systems

Performance Analysis of Optical Time Division Multiplexing Using RZ Pulse Generator

A communication system sends the signals from one place to another, whether separated by a few kilometers or by transoceanic distances. An electromagnetic carrier wave carried these signals with vary frequency from few megahertz to terahertz. Higher frequencies are used in optical communication systems. Optical communication is also called light wave systems. To send the optical signals from on...

Picosecond Pulse Generation for High-Speed Optical Time Division Multiplexing Systems

In an ultrahigh speed OTDM system, picosecond or subpicosecond optical data pulses are transmitted through a fibre link. The optical pulses used in such OTDM systems should have the following characteristics: narrow pulsewidth, high extinction ratio, small timing jitter, repetition-rate tunability, and long term stability. Up to now, several techniques have been developed to produce optical pul...

Generalized Coincident Pulse Technique and New Addressing Schemes for Time-Division Multiplexing Optical Buses

Time-division multiplexing (TDM) optical buses have applications in computer networks, high-performance routers and switches, and interprocessor communication subsystems of parallel computers. Three waveguides are used to implement the previously proposed TDM optical bus. One waveguide is used for data transmission, and the other two waveguides are used for processor addressing. The coincident ...
