Huawei, Ciena, ZTE, and Nokia stand as the top four vendors in optical transport equipment market for 1Q 2021, according to Dell’Oro Group.
Among the top four, Nokia gained the most revenue share over the year ago quarter.
The growth was nearly flat mainly due to the decline in North American market (15 percent) that offset the Y-o-Y growth in other regions, the report said.
Carribean and Latin America showcased 15 percent whereas EMEA region demonstrated 10 percent growth. The APAC market remained flat with no growth over the year ago quarter.
“Although the North American region was down this quarter compared to last year, it did improve from last quarter,” said Jimmy Yu, vice president at Dell’Oro Group. “In fact, the growth quarter-over-quarter was really strong. It grew just a little over 15 percent, and we think this strength will carry forward through the remainder of the year,” added Yu.
Ciena, Huawei, and Infinera are actively shipping 800 Gbps-capable coherent line cards. However, due to the company’s early entry, Ciena holds the lion share of shipment volume.
Communication service providers comprised 71 percent of WDM market revenue in the quarter, the report said.
