Abstract

A recirculating optical fiber loop controller (ROFLC) is essential equipment for experimental verification of long-haul optical fiber communication transmission. In this experiment, the integrated acousto-optic modulators are controlled by a timing circuit composed of counters and comparators in a field programmable gate array (FPGA) to control the on–off of the optical signal. The ROFLC is introduced into the communication system to achieve 4 quadrature-amplitude-modulation (QAM) signal at 32 GBaud, over 8000 km single-mode fiber (SMF) transmission utilizing polarization division multiplexing (PDM). The ROFLC makes possible a low-cost and lightweight optical fiber communication system, and strongly promotes the application of optical fiber communication systems.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
