Nokia reiterated its commitment to 25G PON in its two-day briefing with industry researchers this week. It also shared some interesting commentary about is progress with Fixed Wireless Access (FWA) and its consumer Wi-Fi devices. But, what makes Nokia’s 25G announcement so interesting is that there is significant controversy associated with the 25G standardization process; 50G PON is also in the race for standardization, too. It seems that the world will split into two purchasing groups: Chinese and Western. We think the fact that two purchasing groups will emerge is a material negative for the telecommunications industry and is a sign of things to come. Nokia has decided to chart its own path, find partners, and make the best of this controversy. Our view is that Nokia’s 25G PON offerings will see more demand than 50G PON in the upcoming years, and when 50G finally becomes necessary, Nokia can move to support it.
For background, in May 2020, Huawei announced to analysts that it is backing a 50G standards process, in cooperation with the ETSI. Huawei calls its 50G development “F5G,” which stands for Fixed 5G. It demonstrated over a video presentation an FPGA-based prototype, and it and explained that it expects this technology to be adopted first by the mobile infrastructure market for connecting RAN radio systems to baseband systems and for backhaul. Then Huawei expects the market will develop for residential PON, and later for enterprise campus connectivity (to replace Ethernet switches). Huawei explained that in February 2020, it has the support of Chinese operators, ETSI members in Switzerland, a European operator, Altice Portugal, and Chinese operators.
On the other hand, Nokia had developed a chipset that specifically supports both GPON and next generation PON technologies; it is called Quillion and has been available for nine months. Nokia had consistently explained on several occasions in the past several months that during a February 2020 ITU meeting relating to 25G PON, 18 members of the ITU were in favor of initiating the 25G standardization project (including ATT, BT, Korea Telecom, nbn Co, Telecom Italy, SK Telecom, Telus etc). However, there was a minority coalition led by operators and vendors from China that objected to the proposal on the grounds that 25G PON would pre-empt their futuristic vision of 50G PON. This in turn resulted in no consensus being met.
In response, Nokia has worked with operators and suppliers interested in pursuing 25G PON in the near-term, which we interpret as the next 1-2 years. This MSA (multi-source agreement) strategy is used by various groups in the technology industry when there is sufficient buying power to move ahead of (or in this case, without) standards ratification; we see if used frequently by hyperscalers when building their bleeding-edge data center infrastructures. We understand that there are a handful of operators, including Chorus (New Zealand), Chungwa Telecom (Taiwan), and NBN (Australia) and several technology suppliers including AOI, MACOM, MaxLinear, Ciena, Tibit and others. The MSA has a website with more information.
Nokia explains that 25G PON shares the same optical technologies as those used in Ethernet Switches that are common and used by data centers and campus switching environments. Sharing common optical technologies with high volume data center deployments will reduce costs . Our view is that in a few years, data center switching demand for 25G optics will continue to rise, and this is perfect timing for Nokia and others who are going to use 25G for PON because the supply will be there and this technology will be mature and lower cost.
There’s one other thing to consider that pits Nokia against others. It decided to develop its own semiconductors to power its infrastructure PON systems (OLTs). Nokia’s chip system is called Quillion, and its introduction means it won’t be dependent upon OLT chip vendors.
What’s even more interesting about this whole debate is just how future-looking it is. PON has moved through two main generations, GPON (2.5 Gbps), 10 GPON (XGS and XGPON), and now we are talking about two different generations, 25G and 50G. Huawei’s 50G “F5G” approach is a “if you can’t join ‘em, beat em” strategy, where Huawei will leverage its home market telecom operators’ volume and a few others to work outside its home territory. Huawei will leverage this technology to three markets over time: 5G backhaul, residential PON and enterprise networking. On the other hand, Nokia is taking matters into its own hands in that it has developed its own chips. What’s happening now is not uncharted waters, but it is rare for the telecommunications industry to splinter into multiple buying groups – usually standards are developed and followed for the benefit of the industry. This time, in the absence of standards, Nokia has forged on ahead on its own and its headstrong ways are likely to benefit it because many Western operators and now actively seeking to diversify away from Huawei in their procurement of fixed network equipment.
Yesterday, Ericsson and Juniper announced plans to partner to tackle 5G transport challenges together. Additionally, Ericsson announced a partnership with optical transport company, ECI. The companies said that Ericsson's Router 6000 product family will focus on fronthaul and backhaul and edge compute and will be complemented by Juniper MX, PTX and SRX Series portfolios providing edge, core and security capabilities. Additionally, in today's presentation to analysts, Ericsson showed that the overall transport capability from Ericsson will also include Optical Transport from both ECI Telecom and Ciena. The Ericsson Network Manager will be capable of managing not only Ericsson products, but also the three families of products from Juniper.
ECI will be used for Metro, and will be completely integrated with the Ericsson OSS platform. The company conceded that it is de-emphasizing its in-house metro optical product line and focusing on ECI. Ciena will be used for long-haul transport predominantly, mainly the Ciena 6500 product. Ericsson concedes that both ECI and Ciena products can move to other domains.
To enable automation for 5G, Ericsson can only guarantee that networks working with Ericsson and its partners can successfully be automated. This automation / partnership topic illustrates just how complex it will be to make 5G networks work properly.
Recall that Ericsson and Juniper had a close partnership that goes back many years. In fact, the Juniper router predecessor to the MX was used as the underlying hardware for Ericsson's very important GGSN/SGSN and later EPC capabilities. Ericsson eventually replaced the Juniper product for EPC with its own Router 6000. Subsequently, Ericsson announced a partnership with Cisco, which was more general in nature. That relationship did not result in much tangible progress, from what we have learned; and the relationship was done under previous management teams for both Cisco and Ericsson. Ericsson explained today in its analyst briefing that Cisco and Ericsson compete in several areas. So, this new Juniper relationship is important in that it re-kindles an old relationship and plays to both companies' strengths.
