50G ConsortiumHuawei has delivered a testable 50G unit to China Mobile and passed testing at the European Advanced Networking Test Center.

They also offer a 100 gigabit unit with four 25 gigabit devices. A 2 x 50G unit is planned that will be air-cooled.

Verizon has chosen 40 gigabit NG-PON2 for small cell backhaul, but most other carriers are choosing ten gigabits. Verizon has been testing NGPON2 from Calix and Adtran for a year and is now deploying hundreds of 5G small cells.

[50G] would make sense for two reasons. The datacenter consortium is already planning to define a 50G rate, and 56G serial serdes and optical interconnects are in the works that would likely become the next big building blocks in communications.

The three Chinese carriers, backed by their suppliers, earlier this year brought a proposal to the IEEE, Reconsiderations on 50G and 100G EPON

PON evolution in China Market 

• Next generation PON after 10Gb/s is expected to satisfy the service requirements around 2025 From massive deployment point of view, most probably to evolve from 10G platform (OLT) directly to 50G/100G

• From massive deployment point of view, most probably to evolve from 10G platform (OLT) directly to 50G/100G

• From massive deployment point of view, most probably to evolve from 10G platform (OLT) directly to 50G/100G

• TDM PON (EPON and GPON) has been successfully deployed and operated in China for many years mainly for residential broadband access, showing great advantages. Hence we suggest to consider and evaluate the possibility of a single wavelength system with enhanced line rate such as 50Gb/s, when developing next generation PON system


The new units are part of Huawei's 5G bearing-oriented X-Haul system. They use the term "bearing" to describe backhaul and fronthaul systems.

Huawei's 5G Bearer Oriented 50GE FlexE-based Slicing Router Passes EANTC Testing


[Shenzhen, China, October 13, 2017] Huawei recently announced that its 5G bearer oriented 50GE FlexE-based slicing router has successfully passed the stringent testing of the European Advanced Networking Test Center (EANTC) — internationally recognized as one of the world's leading independent test centers for telecommunication technologies, making Huawei the first vendor to complete independent third-party testing of 50GE FlexE. This testing indicates that 50GE FlexE is ready for commercial use.

EANTC conducted a range of networking tests on Huawei's 50GE FlexE-based ATN series slicing routers, covering 50GE operation modes and FlexE-based network slicing, bandwidth expansion, and protection switching. According to the test results, 50GE interfaces met commercial use requirements for all evaluated indicators. It was found that FlexE-based network slicing could ensure strict isolation between network slices to guarantee service quality.

In the case of congestion, the bandwidths and latency measurements of each network slice met the expectations for inter-slice service isolation and intra-slice statistical multiplexing, meeting the isolation and ultra-low latency requirements of 5G services. FlexE-based network slicing also allows the on-demand addition, deletion, and modification of network slices.

The test results showed that a 50GE interface could be expanded to 100 Gbit/s through FlexE bonding. In terms of reliability, slice protection switching could be completed within 36 ms — far less than 50 ms, the protection switching time required for carrier-class reliability.

Co-founder and Managing Director of EANTC, Carsten Rossenhoevel said: "Huawei's 50GE/100GE FlexE network card performed well across all of our tests. The EANTC team was able to verify its usability for future 5G mobile network deployments."

Since 5G is approaching, bearer networks should get ready in advance. This testing is an important milestone for Huawei's 5G bearing-oriented X-Haul solution, which provides flexible bearing for long-term evolution, on the path toward commercial deployment.

“My three biggest customers are marching to 7 and 5 nanometers.” Lip-Bu Tan. Moore’s Law ain’t dead yet.

Eric Xu, current Huawei Chairman, said consumers would find no “material difference between 4G & 5G.” Dozens of top engineers agree the "5G Revolution" is hokum, including  DT CTO Bruno Jacobfeuerborn, FT/Orange SVP Arnaud Vamparys, and BT CEO Gavin Patterson.
     Politicians and marketers pushed b_______. What’s coming for 5-10 years is good for telco capacity but otherwise disappointing. Unfortunately. 
     On the other hand, mmWave & Massive MIMO are improving at a ferocious rate, advancing telco capacity enormously. Massive MIMO has made it practical to use 3.5 GHz frequencies, a second remarkable booster. The "5G Revolution" is dead; Long Live the real 5G and advanced wireless!
U.S. attacks on Huawei and ZTE look to be an historic disaster.

China’s logical response is to invest to become independent of the U.S. They already have $100B on the table for memory chips and are rumored to add another $100B. Huawei/HiSilicon already holds their own against Qualcomm and everyone else in the world. 
    Zeng Xuezhong of Spreadtrum, world #3 mobile chipmaker, confirms: China will “speed up the chip R&D investment that is self-controlled and self-researched. We must never forget to make it bigger and stronger.”
     U.S. warships patrolling China’s seas inspire security fears. So does Trump’s threat to a country on China’s border."Military solutions are now fully in place, locked and loaded, [for] fire, fury and frankly power, the likes of which the world has never seen before.”
     China would be stupid not to have domestic capacity just in case. The Chinese leadership is not stupid.
