MWC and OFC provide a great opportunity for companies to make new product and technology announcements, and on 20 February 2019, Ciena announced plans for its next-generation coherent optical chipset named WaveLogic 5. WaveLogic 5 will be made available in two variants, covering applications from single span unamplified links through long-haul and subsea networks. The WaveLogic 5 Extreme (WL5e) is optimized for performance and flexibility, operating between 200G and 800G per wavelength, while the WaveLogic 5 Nano (WL5n) is optimized for footprint and power dissipation, operating between 100G and 400G per wavelength. Ciena is developing separate DSPs for each platform in parallel using 7 nm silicon for both. It is also employing vertically integrated high speed electro-optic component technology for footprint optimized coherent optics.
