Telxius’ BRUSA cable successfully reached record 550 Gbps single-wavelength channel speeds during an advanced trial leveraging Ciena's WaveLogic 5 Extreme (WL5e) coherent optical solution. In addition, a commercially deployable solution for a total capacity of more than 20 Tbps on a single fiber pair was verified. With WaveLogic 5 Extreme, the BRUSA cable is now able to reach a total transmission capacity of more than 160 Tbps. This record-breaking trial has demonstrated how the BRUSA network can prepare for increasing connectivity demands from telecom operators, OTT services and other requirements driven by high-bandwidth applications. BRUSA enables ultra-high broadband services, improves communication reliability, overall network performance and provides direct access to internet exchanges in Rio de Janeiro and São Paulo. During the trial, the BRUSA network experienced record connectivity speeds powered by Ciena’s WaveLogic 5 Extreme, the programmable 800G solution. WaveLogic 5 Extreme was used on the BRUSA cable to provide greater scale and increased economic efficiencies and deliver 50% more capacity per wavelength.
