Extensive mud volcanism, mud diapirism and carbonate chimneys related to hydrocarbon-rich fluid venting are observed throughout the Spanish^Portuguese margin of the Gulf of Ca ¤diz. All the mud volcanoes and diapirs addressed in this paper lie in the region of olistostrome/accretionary complex units which were emplaced in the Late Miocene in response to(More)
One of the possible solutions is to use space division multiplexing in order to overcome the capacity crunch. Few mode fibers (FMF) have attracted a lot of attention in the recent years, however still a lot of research is required to enable transmission over FMF. One of the problems with the realization of FMF transmission is that these fibers have a modal(More)
Optical OFDM is a promising modulation format for next generation fiber-optic transmission systems. The main challenges for optical OFDM are its sensitivity to laser phase noise and high PAPR. In this paper the phase noise tolerance is investigated for the two main phase noise compensation algorithms: carrier phase estimation (CPE) and RF-pilot (RFP)(More)
Currently available electrical components put a limit on the maximum achievable symbol rate per channel and order of modulation for coherent optical transmission systems. Hence, future optical transmission systems are expected to utilize superchannel structure for the long-haul transmission of data rates as high as 400 Gb/s and 1Tb/s. In this paper we(More)
Mode-division multiplexing has emerged as an imminent step to increase the capacity of long-haul transmission systems and avoid the so-called “capacity crunch”. One way to realize such systems is by means of few-mode fibers (FMFs). One of the challenges that has to be addressed in order to implement FMF-based commercial systems is the(More)
Recently, coherent optical orthogonal frequency division multiplexing (CO-OFDM) has been considered for the next generation 400-Gb/s long haul data transmission. For long haul transmission systems coherent detection is beneficial compared to direct detection as it provides higher sensitivity. Though CO-OFDM offers a virtually unlimited tolerance against(More)
