“…With a length of 119 km and equipped with 3 fiber pairs and 3 submerged repeaters, it offered a total capacity equivalent to 7,680 voice channels. This system allowed AT&T to prove this new technology and demonstrate that it could be efficiently repaired, and thus this experience made it possible on 1988 the installation of TAT-8, the first intercontinental system with fiber optic digital technology, as exposed by Dawson et al (1984). The advent of repeaters with optical amplifiers and new technological advances, such as Dense Wavelength Division Multiplexing (DWDM) and Forward Error Correction (FEC) made it possible to reach 640 Gbit/s (64 wavelengths at 10 Gbit/s) per fiber pair and much more.…”

Purpose This paper aims to study the competition problems and market failures in the Canary Islands and propose an alternative management model for the telecommunication transmission network. This model is based on a wholesale-only open-access transmission network, available to all the retail service providers of this region, and managed by a unique entity subject to regulation with cost-based prices. The proposal hopefully will help to debate about the implementation of certain regulatory models in the network industries, concerning telecommunication submarine cables connecting archipelagos. Design/methodology/approach An empirical approach has been used, based on the observation and analysis of the regulatory policies applied to the wholesale transmission networks in the Canary Islands, Azores and Madeira archipelagos. Findings Results show a persistent margin squeeze situation on the retail broadband market in the Canary Islands, due to the pricing strategy on the Spanish mainland-Canaries wholesale market, which is, in turn, delaying the entry of alternatives and the level of development and efficiency of competition. The risk of duopoly collusion is also present on this wholesale market. Additionally, public aids will be needed to replace the systems connecting with the non-capital islands and to provide redundancy to El Hierro. The alternative proposal might help preventing the above. Eventually, several insights are considered for further investigation. Originality/value Little attention has been paid to this topic in the literature, regarding the analysis of regulatory policies applied over fiber optic submarine cable infrastructures in fragmented territories like archipelagos. Consequently, an empirical analysis has been accomplished to emphasize this research work, based on the regulatory policies adopted.

“…This allowed final design and reliability programs to begin in confidence. By 1985, AT&T will be installing a prototype system in the C a n q ' Islands [6], and by 1988 the TAT4 system will be available for service using 1.3-pm single-mode technology [71.…”
