Ukraine's Eurotranstelecom (ETT) is extending its 100G network to cover the country's major industrial centers thanks to the rollout of Ciena's (Nasdaq: CIEN) 100G coherent optical technology across the incumbent telco's backbone network. The high-speed project is an extension of one which. Breakout-capable 100G modules are optical transceivers or cables designed to split a single 100Gbps port into multiple lower-speed channels, typically four 25Gbps or 10Gbps links. This functionality allows a single high-speed port to serve multiple lower-speed devices, improving network flexibility. Modern data centers rely on high-speed optical links, and 100G optical transceiver modules (especially the QSFP28 form factor) are now foundational for this connectivity. 100G transceivers convert electrical signals to laser light over fiber, enabling top-of-rack switches to connect to aggregation. Listen to online The total length of the Ukrtelecom optical network is twice the circumference of the Earth In recent years, Ukrtelecom has been actively developing its optical infrastructure through investing in the development of an FTTH/P network based on the GPON technology.
