“…To determine the sign of the dispersion has thus far required one to repeat these measurements at a series of optical carrier frequencies (wavelengths) or other techniques entirely, such as the differential phase-shift method [2]. Additionally, to extract the dispersion per-unit-length of the fiber requires a separate measurement of the fiber length [7].…”

Long haul fiber optic links Chromatic dispersion PERFORMING ORGANIZATION NAME(S) AND ADDRESS(ES) SPONSOR / MONITOR'S ACRONYM(S) 9. SPONSORING / MONITORING AGENCY NAME(S) AND ADDRESS(ES) SPONSOR / MONITOR'S REPORT NUMBER(S)In this work we demonstrate a new technique for measuring the chromatic dispersion of an optical fiber using the baseband RF response of a phase-modulated analog optical link in concert with a well-characterized fiber that serves as a dispersion reference. We show that optical phase modulation provides increased measurement resolution and immunity to optical modulator bias-drift as compared to baseband methods utilizing optical intensity modulation. In addition, we provide a simple derivation of the dispersion response of a long analog optical link to both intensity-and phase-modulated signals and derive simple expressions for the resolution of baseband chromatic dispersion measurements employing both types of modulation.

“…In addition, second-order harmonic and intermodulation distortions are enhanced by chromatic dispersion in multi-octave systems 22 . SBS in long-haul APLs can be reduced via engineering of the transmission fibre, e.g., concatenating fibres with different SBS frequencies 23,24 , the use of few mode fibres 25 , via aluminium doping 26 , or use of optical isolators along the fibre length 23,27 . Other strategies involve engineering of the transmitter, e.g., using frequency comb sources 28,29 , dithering 30 , or optimized modulation formats 31 .…”

Low-loss microwave photonics links using hollow core fibres

There are a host of applications in communications, sensing, and science, in which analogue signal transmission is preferred over today’s dominant digital transmission. In some of these applications, the advantage is in lower cost, while in others, it lies in superior performance. However, especially for longer analogue photonics links (up to 10 s of km), the performance is strongly limited by the impairments arising from using standard single-mode fibres (SSMF). Firstly, the three key metrics of analogue links (loss, noise figure, and dynamic range) tend to improve with received power, but this is limited by stimulated Brillouin scattering in SSMF. Further degradation is due to the chromatic dispersion of SSMF, which induces radio-frequency (RF) signal fading, increases even-order distortions, and causes phase-to-intensity-noise conversion. Further distortions still, are caused by the Kerr nonlinearity of SSMF. We propose to address all of these shortcomings by replacing SSMFs with hollow-core optical fibres, which have simultaneously six times lower chromatic dispersion and several orders of magnitude lower nonlinearity (Brillouin, Kerr). We demonstrate the advantages in this application using a 7.7 km long hollow-core fibre sample, significantly surpassing the performance of an SSMF link in virtually every metric, including 15 dB higher link gain and 6 dB lower noise figure.
