RETN added Tokyo-Khabarovsk section to its network

RETN added a new submarine section to enhance its network in Asia: Tokyo – Khabarovsk. Based on RJCN, a fibre optic submarine cable network launched in 2008 to link Japan and Russia, this link offers additional redundancy to connect Asia and Europe across the RETN network. Customers can now enjoy a fully protected alternative route to have their connectivity between Japan and major European markets organised and/or back-upped through one homogeneous network.

Since 2016 RETN operates a high-capacity terrestrial network connecting Hong Kong to Europe via Kazakhstan (TransKZ). The Tokyo – Khabarovsk submarine section provides additional redundancy for RETN’s network in Asia-Pacific as well as connecting RETN’s network assets in Japan with Russia and Europe at reduced latencies.

RETN provides reliable and secure Internet and Ethernet&VPN services between Tokyo and Europe via RJCN cable and terrestrially across Russia. To support businesses in their operations and growth in the direction from East to West.

Currently RETN has 3 PoPs in Tokyo city interconnected by a metro dark fibre ring, and a vast network coverage in Russia and Europe. For more information mail at
