1. Fully diverse and fully buried dark fibre pairs or individual strands available for lease or IRU between IColo1, IColo2, Telehouse, Nyali Exchange, Seacom CLS, and 2Africa Shanzu CLS. Unlike other providers, the fiber connects to the data centers via buried conduits. Not power poles. End to end burial. 2. Sixty Euros per kilometer on three year lease deals. 3. New ultra-loss fiber manufactured in 2024. 4. Repair SLA based on 4 hours mean time to repair.

Zayo's High Capacity English Channel Subsea Fibre Optic Cable: Zeus

Image
The American carrier Zayo has an extensive European wide area network as well as a highly ranked international Internet backbone. Its relatively new subsea Zeus cable links Amsterdam to London via a double armored 96 fibre pair system buried on average between 2 and 3 meters deep. Although Zayo's press releases nowhere states it, any 96 fibre pair cable is undoubtedly unrepeatered just like Scylla and CrossChannel because a repeatered system would probably require more power than possible. Repeatered 96 pair cables do not exist. And like Scylla, Zeus uses ultra-low loss fibre. Probably the Corning SMF28 product. The cable's current throughput is 2.6 petabits per second with the potential to do up to 4 petabits.  One reason both Scylla and Zeus are buried so deep is that the North Sea sediment layers off the  Netherland's coasts are not stable. They move carried by the North Sea's strong wind and sea currents. This necessitates deeper burial to ensure the cable does no...
