800G COMES TO THE FOREFRONT


Early in 2019 two companies announced their roadmaps for the next generation of coherent technology, focusing on new DSPs and optics designed to reach maximum speeds of 800Gb/s. Tis was in the run-up to the OFC event and the post-show report said that this technology would be capable of delivering speeds of 200Gb/s and 400Gb/s over longer distances. Like 400ZR, these DSP chips use the latest generation (and most expensive) 7nm silicon processes and cost tens of millions of dollars to design and prototype. Infinera’s launch was the sixth-


generation Infinite Capacity Engine, ICE6, which features dual-channel 800Gb/s per wave. Part of Te Infinite Network, ICE6 builds on the ICE4 and Instant Bandwidth with a 1.6Tb/s optical engine, allowing network operators to meet bandwidth growth requirements and increasingly dynamic, unpredictable traffic flows. Te network consists of the


Infinite Core, the Infinite Edge and Cognitive Networking. Te Infinite Core addresses operator challenges in core networks, delivering optical performance from metro to subsea, including 600Gb/s per wavelength transmission, improved capacity- reach performance and flexible, scaleable soſtware defined capacity on demand with Instant Bandwidth. Building on these capabilities, the newly launched ICE6 is engineered to deliver up to 800Gb/s per wavelength and an expanded toolkit of advanced coherent technologies. Packaged in a cross-platorm


digital coherent module, ICE6 combines the company’s sixth- generation photonic integrated circuit (PIC) with its in-house 7nm FlexCoherent digital signal processor (DSP) technology. ICE6 is available already, with the FlexCoherent 6 DSP available in quarter three, and the complete optical engine available by end of year. Platorms powered by ICE6 are due to be available in the second half of 2020. Dr Dave Welch, Infinera founder

DCI applications, to extended- temperature, standards-based optical modules for access applications, to compact coherent optics with seamless photonic layer integration for certain metro/ regional applications. Te WaveLogic 5 range will


be available in the second half of the year. WL5e and WL5n technology will be offered across the company’s Converged Packet Optical and Packet Networking portolios, and will be made available for use in third-party equipment via Ciena’s Optical Microsystems portolio. Scot McFeely, senior vice-


ICE6 is readily available


and chief innovation officer said: ‘Similar to the launch of ICE4, ICE6 will transform the market by delivering cuting-edge technology, designed in-house, enabling network operators to respond to the insatiable demand for capacity quickly, while optimising costs.’ Ciena’s addition was the


WaveLogic range of technology products, which includes a single-wavelength 800G solution. Te technology is delivered in two solutions: WaveLogic 5 Extreme (WL5e) and WaveLogic 5 Nano (WL5n). In WL5e, tunable bandwidth up to 800G provides what the company calls significant efficiency advantages over 600G solutions, allowing customers to take advantage of the pending introduction of 400G interfaces in the data centre. A range of form factors allows customers to choose the best option in meeting network architecture requirements for certain applications based on space, power and operational requirements. WL5e provides programmable


capacity in 50G increments over a single-wavelength 800G solution, which means, according to Ciena, that it delivers 50 per cent more capacity per wavelength and up to 20 per cent higher spectral efficiency. It also enables an evolution to emerging 400GbE- interface routers, with the ability to efficiently transport 400GbE client rates at any distance, from across the metro to across the ocean.


27 WL5n addresses the market


of footprint-optimised coherent solutions for 100G-400G applications. It supports a range of solutions that meet specific space, power and operational requirements, from standalone pluggables for 400ZR single-span


president of global products and services at Ciena, said: ‘WaveLogic 5 is another example of our leadership ability at work, underpinned by the financial strength, global scale and superior engineering expertise that affords us the confidence in continuing to deliver as promised on our forward roadmap commitments.’
