Chinese equipment maker Huawei and Russian incumbent RosTelecom have teamed up for yet another 100G test. The trial featured coherent 100G and ePDM-QPSK over a 1,033km stretch of Rostelecom's live network between Moscow and Samara. They also tested hybrid 100G/40G transmissions.
Samara isn't a household name in the US, but it's Russia's sixth largest city and lies to the southeast of Moscow in the Volga region just on the edge of the Russian steppe. The Moscow-Samara route is one of Rostelecom's busiest, and probably features in many of the Europe-Asia terrestrial links that have been making more news lately.
Huawei has long been an aggressive challenger to the main players in the transport market, and they are clearly also gearing up for next year when 100G will probably begin to go mainstream.
