Cables connect server racks 
Rostelecom has completed work on the Bulat DWDM system, a platform designed for backbone and international communication links.The system provides up to 96 optical channels at speeds running from 10–200 Gbps — over a single fiber pairModular by design, it lets operators scale up capacity by dropping in a new transmitter at a different wavelength. And even more important — no new cables requiredWorks with third-party hardware and software, and can plug into existing networks without vendor lock-inNext-generation cards targeting 400–800 Gbps are in the works, with prototypes expected in 2027With Bulat, Russia slashes dependence on foreign DWDM suppliers, which is a major stride toward digital sovereignty.
