Growing Demand in the Optical Transport Market

According to a recent forecast published by Dell'Oro Group, the Optical Transport Equipment market is poised for significant growth, with an expected increase of 16% in 2026. This boost is anticipated due to a burgeoning demand for network infrastructure, largely driven by advancements in AI data centers.

In a detailed analysis, Dell'Oro Group's Vice President, Jimmy Yu, noted, "We raised our full year 2026 forecast from 10% to 16% following standout results in the first quarter of 2026." The report underscores that the first quarter of 2026 saw the Optical Transport market witnessing a remarkable 20% year-over-year growth, fueled by heightened demand for data center interconnectivity.

Despite this impressive expansion, there's concern regarding supply chain constraints, as many leading suppliers in the optical transport sector are experiencing a growing backlog of orders. This situation raises the possibility that supply issues may restrict the market’s growth rate from climbing even higher in 2026. Yu explains, "We think supply may be the biggest factor keeping the Optical Transport market's growth rate from being even higher this year due to all the AI data center build-outs."

Highlights from 1Q 2026

Dell'Oro Group's Optical Transport Quarterly Report provided several key highlights:

• - The growth of 20% year-over-year in 1Q 2026 was largely attributed to significant revenue increases in Wavelength Division Multiplexing (WDM) Systems and Integrated Passive Optical Devices (IPoDWDM) ZR/ZR+ optical pluggable modules.
• - Revenue related to direct purchasing for Data Center Interconnect (DCI) is estimated to have surged 40% year-over-year.
• - Notably, regions such as North America, Europe, and the Middle East Africa (MEA) showed year-over-year growth, while Asia Pacific and Latin America faced declines.
• - When analyzing the revenue from the top Optical Transport Systems vendors, Huawei, Ciena, Nokia, and ZTE collectively accounted for over 80% of the market share. For IPoDWDM ZR/ZR+, prominent players included Marvell and Cisco Acacia.
