Subsea Cables & Internet Infrastructure

***No European terrestrial routes are more subject to outages than those linking EU nations to Turkey via Bulgaria. Many so-called diverse routes share a common pinch point, namely the same conduit system alongside a Bulgarian road that goes to the Turkish border. Rumor has it that this conduit system was not properly permitted and hence lacks proper legal protection. Construction-caused outages are rampant on the Bulgarian side of the border. Outages peak in the summer.  ***Fully diverse diverse routes linking Sofia Telepoint to Mednautilus, Istanbul. Several border crossings. Three year 100G wave MRC: 6500€. No use of oil or gas pipelines. Two fully diverse 100G waves are 12K Euros.

Turkey has bee a very tough market for global ISPs. Until EXA lit terrestrial fibre a few years ago across the Bulgaria's border with Turkey, 100G pricing was $15K per month and above. EXA now dominates the key Frankfurt to Istanbul route with lower pricing. But the situation is not ideal. Physical diversity is an illusion across the narrow border with one conduit system carrying much of the international traffic. Sparkle's old Mednautilus system does provide an alternative to the land routes, but it's primacy has been too high for foreign ISPs in Turkey to flourish. Sparkle has signed a memorandum of understanding with Turkcell to build a subsea cable that will land in the Instanbul suburd of Izmir and at Chania, Greece. The yet unnamed cable will interconnect at Chania, a Greek island, to the BlueMed cable which will carry the traffic to Marseille, Milano, and other key telecom hubs. We have few details on the cable itself other than a target design throughp...
