ZTE tests co-routing detection in an existing optical network

ZTE completed a commercial trial of co-routing detection in China Mobile’s existing optical network in Yunnan Province, China. 

The trial with the Yunnan branch of China Mobile, involved two scenarios: co-cable routing detection and co-ditch routing detection. The trial result shows that there will be an early warning of active/standby paths in the same optical fiber or route so that it can be avoided in time based on fiber sensing.

According to the verification, ZTE's optical network co-routing detection function can exactly detect co-cable routing of 14 optical cables and 54 fiber cores by dynamic parameter optimization, AI algorithm and experience threshold adjustment. Also, ZTE takes analysis, contrast and on-site specialist inspection to exactly detect co-ditch routing of 12 optical cables and about 20 ditches in 4 core equipment rooms. The verification proves that ZTE can provide the operator with flexible optical network co-routing detection methods, along with real-time, accurate and reliable intelligent O&M measures, which well guarantees service survivability and alleviates the difficulty in dumb fiber resource management.

"The function can effectively solve actual problems in production and operation. Before this, active/standby routes are planned on the resource management map, and routing is determined manually, which leads to high error rate. Additionally, the accuracy of resource management information is hardly under control, thereby increasing routing risks,” said the leader of Network Management Center of China Mobile Yunnan.

“In the original routing detection, people pulled or pushed the cable underground manually, which resulted in low efficiency and service interruption. However, the co-routing detection now leverages dumb fiber resources without service switching. The innovative function remarkably reduces manpower and ensures service survivability while allowing resource management information modifications and route re-planning to avoid service interruption losses," he added.

SpaceX completes 57th Starlink launch

On Friday, August 19, SpaceX launched 53 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida.

This was the ninth flight for the Falcon 9 first stage booster supporting this mission, which previously launched GPS III Space Vehicle 04, GPS III Space Vehicle 05, Inspiration4, Ax-1, Nilesat 301, and now four Starlink missions.

The mission was SpaceX’s 57th Starlink mission to date. 

It was SpaceX's third Starlink mission in August and 23rd Starlink mission this year.

Dell'Oro: RAN Disappoints in 2Q 2022

The positive momentum that has characterized the Radio Access Network (RAN) market over the past four years is losing some steam, according to a new report from Dell'Oro Group. The overall 2G-5G RAN infrastructure equipment market – including hardware and software – declined in the second quarter, recording the first year-over-year contraction in more than two years and the third consecutive quarter of RAN coming in below expectations. Although the RAN market is not immune to external risks, initial readings suggest that the RAN impact from deteriorating macro conditions, high levels of inflation, and supply chain disruptions were limited in the quarter.

"The shift in the pendulum is not a surprise, but admittedly it has swung a bit faster toward the negative than initially expected", said Stefan Pongratz, Vice President at Dell'Oro Group. "Slower momentum is not a sign that the 5G deployment phase is over. The message we have communicated for some time now, namely that the 5G cycle will be longer than previous technology cycles, still holds. At the same time, market conditions in the quarter were impacted by APAC, excluding China, Russia, and foreign exchange," continued Pongratz.

Additional highlights from the 2Q 2022 RAN report:

  • Top 5 global suppliers in the quarter include Huawei, Ericsson, Nokia, ZTE, and Samsung.
  • Top 4 suppliers outside of China in the quarter include Ericsson, Nokia, Huawei, and Samsung.
  • Huawei and ZTE continued to dominate in China, together accounting for 90 to 95 percent of 1H 2022 revenues.
  • Ericsson maintained its grip on the RAN market outside of China, accounting for 39 percent of the revenues for the 1H 2022.
  • Nokia's RAN position outside of China improved between 1Q and 2Q 2022.
  • Samsung's 1H 2022 RAN share improved both in North America and globally.
  • Even though RAN results disappointed in the quarter and first half revenues are tracking below expectations, RAN is still projected to record a fifth consecutive year of growth in 2022.
