Ciena Tech Acquires OPTK Networks

Image
  OPTK Ciena Networks , a Nebraska-based regional fiber optic provider, is increasing the speed capacity of its 4,000 miles of fiber optic network from 100 Gbps to 400 Gbps. This upgrade was made possible by Ciena's 6500 packet optical transport platform, which was deployed on OPTK's long-haul route from Denver to Omaha. Tim Smith, operations manager at OPTK, said the deployment will meet increasing customer demand and increase network capacity across a wider range of locations. Ciena 6500 hardware includes WaveLogic 5 Extreme 800G and WaveLogic Ai 400G coherent optical modems. WaveLogic 5e, launched in 2020, can send and receive up to 800G of network traffic on a single wavelength. OPTK's dark fiber, wavelength, carrier Ethernet and Internet solutions span Colorado, Nebraska and Iowa, and the company specifically serves businesses, service providers and utilities in the region. Smith said that at OPTK, the primary use case for 400G speeds "overwhelmingly...

Is anyone using 800G today?

Image
  The short answer is yes. With various generations of coherent technology on the market, including 400G-capable, 600G-capable, and with 400G coherent plug-in modules expected to be commercially available in the near future, one may wonder how many operators are actually deploying the WaveLogic 5 Extreme programmable 800g solution today. In fact, in just over nine months since it was commercially available, Ciena has shipped over 6,000 coherent modems to over 75 customers around the world who are in various stages of actively deploying WaveLogic 5 Extreme on their networks. What’s interesting is that these deployments are truly global and span both terrestrial and subsea applications. The map below visualizes the distribution of 800G modems across various regions. North America dominates as the region with the highest early adoption rate, accounting for nearly 40% of shipments. This is followed by Asia Pacific at around 30%, with India, New Zealand, Australia and Japan experi...
