ROADMAP 2022 MOVERS AND SHAKERS


Optics and DSP designed to reach 800Gb/s, coherent pluggable technology, next generation transceivers, along with tools designed with the installer in mind are just some of the big trends for the next 12 months, according to key spokespeople from some of the industry’s best known vendors


Coherent technology continued to be big news in 2021, and for Acacia Communications (now part of Cisco) this shows no signs of slowing down. Te company believes that coherent has evolved in response to growing bandwidth demands. Different baud-rate classes are


grouped based on technological capabilities, industry standardisation (such as OIF, IEEE, Open ROADM, OpenZR+ MSA, CableLabs, ITU) and common industry investments. Te next class of coherent optical products, Class 3, enables a doubling of baud rates from the current Class 2 technology. According to Acacia, throughout this evolution, it has been critical that each successive class provide network architecture compatibility to the previous class, primarily reach and channel width. Acacia’s Class 3 product is


a 1.2T faceplate pluggable coherent module, which highlights what the company refers to as an eighth generation coherent interconnect module family, powered by the company’s Jannu 5nm CMOS digital signal processor (DSP) ASIC. Te Jannu DSP is designed


to offer network operators the ability to maximise transmission data rate across a wide range of multi-haul network applications including DCI, metro, long-haul and subsea. Te architecture of the new


Coherent Interconnect Module 8 (CIM 8) solution builds upon the success of the Acacia


AC1200 product family and aligns closely with the latest client data rates and coherent industry standardization efforts. It is designed to enable network operators to double their transmission capacity over even greater reaches. For links requiring maximum capacity, the new module can provide 1.2T capacity over a single wavelength. Te company’s Class 3 offering


was described by Mehrdad Givehchi, senior director of engineering for hardware and soſtware and founder at Acacia as ‘an exciting new milestone in Acacia’s history as we once again introduce an exciting new product that delivers the type of disruption needed to cost-effectively scale network capacity in the future. With every generation of product, we have been able to deliver higher transmission data rates, lower power consumption and higher performance and I am proud to see this new product carry on that legacy.’ www.acacia-inc.com


Viavi Solutions is of the view that we are accelerating into the age of automation. Dr. Sameh Yamany, CTO, at the firm told Fibre Yearbook: ‘As we look to the future of next-generation fibre networks in 2022 and beyond, it’s increasingly apparent that the need for automation and faster, more reliable testing is not slowing down. Test process automation is being used to speed network buildouts and minimise downtime by transforming field technicians’ workflow to enable replicable testing for faster, more reliable test measurements. Tis is particularly important as more

automated alerts. Tis not only increases workforce productivity, it also helps reduce mean time to repair (MTTR) by pinpointing the root cause of typical field issues such as outages or service degradations related to compromised cable, connectors or hardware. ‘While some network


network operators are relying on contractors to keep up with the explosion in data demand. ‘Similarly, centralised and


remote fibre test and monitoring is quickly becoming an industry best practice. ‘Remote fibre test solutions


simplify the task of network management by enabling remote, hands-free monitoring with


Both 400 and 800G have also been hot topics for II‐VI Incorporated as the company demonstrated a range of 100Gb/s indium phosphide (InP) directly modulated lasers (DMLs) for high-speed transceivers deployed in data centres at the 2021 virtual OFC event. Te growing demand for 400


and 800 gigabit Ethernet (GbE) transceivers is driving investments in technology advancements of DMLs due to their lower cost and lower power consumption compared to electro-absorption modulated lasers (EMLs) currently used in these high-speed transceivers. II-VI’s 100 Gb/s DMLs have the ability to achieve state- of-the-art modulation speed and signal quality at high output power and low power consumption. Tey are built on the company’s


InP technology platorm. Te low power consumption of II-VI’s DMLs and their design for non-hermetic


operations teams perform fibre monitoring as a periodic check, there is a growing trend toward active fibre monitoring that leverages predictive analytics to continually identify service issues or detect network intrusions throughout the entire network lifecycle, resulting in improved total cost of ownership (TCO) and proactive issue resolution. www.viavisolutions.com


packaging are ideal features for today’s pluggable form factors and tomorrow’s co-packaged solutions. Speaking to Fibre Systems


at this year’s virtual OFC event, Sanjai Parthsarathi, II-VI chief marketing officer explained that an overarching theme for II-VI is speed. ‘When we talk about speed we’re really talking about lasers,’ he said. ‘So, the 100Gb/s DML product is for high-speed transceivers. In the transceiver, there are many people in our industry that are skilled in integrating components, but very few people have the technology platorms that enable these advanced lasers, and the laser is at the heart of the transceiver. You cannot generate light with silicon alone, you need laser platorms. We have three or four different major platorms, but this particular one is essentially enabling the next generation of transceivers.’ www.ii-vi.com
