A Unique Terrestrial Cable System to connect Europe and Asia


Solution Overview

TRANSKZ is an innovative express gateway linking Europe to Asia on a single, homogenous, terrestrial, DWDM system from a single network provider.

It is fully protected connecting Europe to Asia with 15,000km of fiber from Frankfurt to Hong Kong (the shortest route) and a 143.18ms round trip delay time.


The system provides a guaranteed SLA of 99.7% for layer 1 services (99.95% for layer 2) with measured up time >99.99%.

Similar up time on subsea systems would typically require n+2 circuits, in order to be achieved and still would not pay SLA credits for any outages.

In the modern world, where global financial, social and gaming communities compete for every millisecond (ms) of round trip delay and every second of downtime counts, TRANSKZ is revolutionising communications between Europe and Asia.


The world has been using subsea cable systems since 1856 at the dawn of the telegraph and we still use them today for the vast majority of intercontinental data transmission. The reasons for their continued use are clear. Easier to provision and plan than terrestrial cables (with their border crossings, wayleaves, and issues with land use rights), they provide cheap, ubiquitous access to a different continent…except when they don’t. The typical subsea cable system is made up of multiple consortium partners, not to mention the backhaul partners from the landing stations.

Installs and upgrades take forever, and that easier provisioning takes a lot of time also. And don’t even think about the mean time to repair in case of a subsea fiber cut, what terrestrially takes 8 hours to repair, on subsea can take 4 months, all the while there are no SLA credits. Of course, traditional terrestrial cables suffer from some of the same issues’ consortiums present, not to mention the additional cost as each partner jostles for their fair share. Now for Europe to Asia, it doesn’t have to be this way.

Unique solution

TRANSKZ is a truly unique solution. There are plenty of pretenders on the market. None ofthem offer the multiple layers of redundancy on a homogenous DWDM network, this is whyRETN can deliver so quickly and provide such great SLAs.

A typical pretender network connecting Europe to Asia uses the DWDM systems of between 3 and 5 different partners. Itdoesn’t take much imagination to understand what happens when there is a problem on thenetwork, or a service delivery needs to be expedited!
