When the first dispersion compensating fiber modules were introduced to the market in the mid '90s, the only requirement to the fiber was that it should have a negative dispersion. As the bit rate and the complexity of the optical communication systems have increased, several other requirements have been added such as low loss, low non-linearities and the ability of broadband dispersion compensation.

“…In that sense, the impact of MPI is similar to that of noise due to amplified spontaneous emission (ASE) in amplifiers, and leads to deterministic systems penalties. Zheng et al [49] have made similar assertions with respect to coherent distributed MPI in HOMs. However, note that a characteristic signature of MPI in HOMs is the slow, bursty evolution of transmitted power, as shown in Fig.…”

Few mode fibers have recently attracted a lot of attention, because of the prospect of enhanced design flexibility, unique modal properties, and the existence of several simultaneous light-paths in them. After the pioneering experiments by Craig Poole from Bell Labs in 1993, an application that faded away but saw a re-emergence in 2000-2003 was higher order mode dispersion compensation. In this scheme, mode converters are used to selectively propagate the signal in a higher order mode of a few-mode fiber.Demonstrations over the last few years have shown that this novel technology can provide several benefits over the conventional dispersion compensating fiber, such as lower nonlinearity, higher dispersions, potentially lower loss, and most interestingly, a format to realize tunable dispersion compensation devices. It also has attendant tradeoffs arising from the need to manage modal interference, and a complex architecture that may make it more costly. This talk will review the physics and technology of the higher order mode dispersion compensator and discuss its future directions.

“…mainly coming from the DRB noise. Note that, when the system employs fiber lasers with the narrow linewidth, using the DCFs will introduce an additional interference noise coming from the modal mismatch between the DCFs and single-mode fiber [32]. This topic is outside of the scope of this article and will be studied in our future work.…”

We report the effect of the double Rayleigh backscattering (DRB) noise, in which the interference of the signal light with the double Rayleigh backscattered light, on the fiber-optic radiofrequency (RF) transfer system. Here, we theoretically analyze and experimentally demonstrate that the DRB noise within the fiber link will become the dominative noise on the fiber-optic RF transfer system once narrow linewidth lasers are used. The strong DRB noise is experimentally confirmed through the measurement of the effect of the coherent interference term of the signal light and the double Rayleigh backscattered light on the 100 km RF transfer system. Our results provide evidence that the conventional RF transfer technique with the telecommunications-grade lasers, in which the chromatic dispersion effect in the single-mode fiber is compensated by dispersion compensation fibers (DCFs), could be the better choice for high-performance RF transfer.
