Embodiment Construction

[0034] The present disclosure generally relates to systems and methods for implementing parallel optical transponders having an optical comb light source that provides multiple carriers from a single light source. Although an optical comb light source is more expensive than a conventional continuous wave light source, it allows simpler, smaller, and / or cheaper components to be used in many other locations in the transponder.

[0035] The main driving force for higher capacity and higher bandwidth signals is the desire to reduce the number of optical components such as lasers, modulators, and photodiodes. Because of the cost and power consumption of lasers, their reduction is particularly interesting.

[0036] The increase in the sampling rate of the dedicated circuit of the digital signal processor has become a factor that enables the capacity per carrier to be increased. For scalability, digital gates and analog front ends—that is, analog-to-digital and digital-to-analog converte...

Abstract

Parallel optical transponders with an optical comb source, and methods of using the same, are provided. The optical comb source can provide multiple optical carriers from a single source. The multipleoptical carriers can be phase-aligned, which can allow joint processing of a received signal. The multiple optical carriers can also allow for modulating a demultiplexed data signal using multiple modulators rather than modulating the entire data signal using a single modulator.

Description

[0001] Cross references to related applications [0002] This application claims the priority and rights of U.S. Patent Application No. 15 / 821,209 filed on November 22, 2017, and the entire content of the application is incorporated herein by reference for all purposes. Background technique [0003] Optical transponders are widely deployed to form long-distance, underground, inter- and intra-data centers networks that carry large amounts of data services. With the development of coherent optical communication technology, the amount of data sent per optical wavelength has greatly increased. With the current generation of so-called line cards, a line-side data rate of up to 200 Gbit / s per optical carrier can be achieved. The increased data rate reduces the number of optical components such as lasers, modulators, and photodiodes, thereby reducing system cost and power consumption. The increase in the speed and complexity of digital signal processors (ie, smaller semiconductor manufa...
